Using A Microscope 101: Important Microscope Parts & Functions

Can you name all the different parts of a microscope? Knowing how to properly label microscope parts is important so you can communicate clearly and provide detailed instructions when teaching a class of young students. Here is everything you need to know about naming the parts of a microscope.

Using A Microscope 101: Parts Of A Microscope

A microscope is used to magnify small objects. Microscopes are often used in scientific or educational settings to observe objects and living organisms that wouldn’t be visible to the naked eye. It is important to learn about the different parts of a microscope to understand how these devices work.

Why Is Knowing About Microscope Parts Important?

Learning about microscope parts provides you with a frame of references. You can use the correct terms to communicate with other scientists or students.

This is crucial when giving instructions. If you are an instructor, you should take the time to teach students about the different parts of a microscope so you can give detailed instructions on how to prepare a microscope and use it safely.

Knowing the correct terms for the different parts of a microscope will also help you troubleshoot problems. You will be able to look up information on a specific part you are encountering issues and figure out how to rectify the issue.

The Basic Components Of A Microscope

microscope diagram

Three microscope parts make up the frame of the device.

Base

The base is the large piece that supports the microscope. You need to keep your microscope steady to get a clear image of what you want to magnify. This is why the base is an important part.

The size of the base depends on how heavy the microscope is. If you need to carry a microscope, make sure you place one hand under the base to support the weight of the device.

Arm

This is the C-shaped section that connects the base of the microscope to the controls and tube. You can typically adjust the angle of the arm to use the microscope more comfortably.

The arm is the first part that young students should learn about. This is the part you would use to safely pick up and transport the microscope. Teach students that they should always grab the arm of the microscope if they need to change the position of the device.

When carrying a microscope, you should hold the device by the arm and have one hand under the base to support its weight.

If you are using a compound microscope, the base, arm, and stage of the device won’t be separate elements. However, these different parts are easily identifiable on most small microscopes with low magnification settings.

Tube

This is a large part at the top of the microscope. The tube is connected to the arm of the microscope.

You will find the turret or nosepiece with the magnifying lenses at the bottom of the tube. However, you don’t directly look down the tube since an eyepiece is mounted on top of the tube.

The tube of a microscope can’t be adjusted. Make sure you teach the name of this part to young students, so they know not to grab a microscope by its tube.

Some microscopes have two tubes and two eyepieces. Most models only have one tube and eyepiece.

How To Magnify An Object

Eight different microscope parts come into play when you use a microscope to magnify an object.

Stage

The stage is the small surface located under the turret or nosepiece of the microscope. This is where you need to place the object you want to magnify.

The stage is equipped with a couple of metal clips that will secure the object you need to magnify to the microscope. You would typically prepare the object or living organism you want to magnify by placing it on a microscope slide and use the stage clips to secure the slide to the stage.

There is a hole called the aperture in the center of the stage. Light comes through the aperture and illuminates the object. You need to make sure the object you want to magnify is aligned with the aperture when attaching it to the stage.

Mirror Or Illuminator

You can’t use a microscope without a light source. The mirror or illuminator is located under the stage and illuminates the object or living organism you want to magnify.

If your microscope is equipped with a mirror, you will need to adjust the mirror to reflect sunlight. Most microscopes are equipped with an illuminator that you simply switch on and off.

You will find a 110v bulb inside of the illuminator. Some microscopes have an iris diaphragm attached to the illuminator that can be used to control how much light comes out.

Turret Or Nosepiece

This is a rotating circle attached under the tube of the microscope. There are different objective lenses attached to the turret of the nosepiece.

The purpose of the turret or nosepiece is to support the different objective lenses and let you select the right one. Microscopes have at least two lenses attached to the turret or nosepiece but can have a lot more.

Eyepiece

The eyepiece is the part mounted on top of the tube. This is where you look into the microscope. The eyepiece usually has a lens with a 10x or 15x magnification power. You can calculate the magnification of a microscope by multiplying the eyepiece lens magnification power by the magnification power of the objective lens you are using.

Stereo microscopes have two eyepieces to create a three-dimensional image of the object. If you are an instructor, you probably won’t be working with stereo microscopes but showing images of these devices to your students could be an interesting way to introduce three-dimensional images and to show them there are different types of microscopes with more features.

Controls

You will find the controls on one side of the arm. Most microscopes use dials or knobs to let you adjust the magnification.

The controls work by bringing the stage closer or further away from the objective lens you have selected. You will usually have a coarse control to make broad adjustments and a fine control for more precise adjustments.

Some microscopes have an additional control mounted on the eyepiece. This is a diopter control to adjust the magnification of the lens you look into.

Some microscopes have an additional control attached to the base so that you can adjust the brightness of the illuminator.

Rack stop

The rack stop is a safety feature that prevents you from bringing the stage too close to the objective lens and accidentally damaging it. The rack stop is a small screw that is mounted next to the stage.

You shouldn’t have to adjust the rack stop of your microscope. The default setting will prevent you from getting the stage too close to the objective lenses.

If you are teaching young students how to use a microscope, make sure they know what the rack stop is and understand why they shouldn’t touch it. It is possible to loosen this screw and get the stage closer to the objective lenses, which could result in some damages to the lenses.

Objective Lenses

These lenses are attached to the turret or nosepiece and hang directly above the stage. Microscopes can have two, three, four, or five lenses depending on their magnifying power.

The magnification power of a lens typically ranges from 4x to 100x depending on how performing the microscope is.

The objective lenses are the most important and most fragile microscope parts. They are protected by small tubes, but students should be aware of how fragile the lenses are.

Condenser lens

Not all microscopes have a condenser lens. The purpose of the condenser lens is to focus the light on the object you want to magnify.

A condenser lens is often used with high magnifications since it gives a sharper image of the object. You can upgrade your microscope by adding a condenser lens, but this is something you might not need if your microscope only has low magnification settings.

The condenser lens is mounted on the stage and will concentrate light on the object.

How To Teach Students About Microscope Parts

children using a microscope

There are different ways to help students remember the different parts of a microscope. Here are a few ideas:

  • Bring a microscope to class and point to the different parts.
  • Have the students label a diagram of a microscope.
  • During activities that involve microscopes, make sure you ask each student to name a few parts.
  • Ask students to explain how they would prepare a slide or transport a microscope. Make sure they use the correct names for the different parts they mention.
  • Ask students to name the parts that come into play when magnifying an object.
  • Ask students what the purpose of a specific part is.
  • Have students try out different lenses and calculate the magnification power for each one.

Knowing the names of the different parts of a microscope is important because it helps you communicate clearly with students or colleagues. Remembering the different parts is easy if you keep a labeled diagram with you and make sure you always use the proper terms when referring to the different parts of a microscope.

Amino Acids: Definition, Charts, and Study Guides

Finding an excellent amino acid chart that is also a good reference and well suited for your needs can be a challenge. However, there are great charts and study guides available that use diagrams, videos, and text to quickly deliver information in a succinct and organized manner.

Amino Acids

Learning about amino acids and finding good charts and study guides can be a challenge, but there are reliable resources available. Our list includes some of the best reference charts and most diverse study guides to fit a variety of learning styles and other preferences.

Whether you are a beginner or a more advanced user, these charts and guides can be helpful in accelerating learning and testing the knowledge that you already possess. For those studying for the MCAT, having these tools at your disposal can help supplement your other materials and verify your knowledge by presenting content in alternative forms.

What Are Amino Acids? What Do They Do?

Amino acids are a class of organic compounds that include at least one carboxyl group, and one amino group. Amino acids are one of 20 different components that go into assembling proteins and are frequently referred to as “building blocks.”

There are a total of seven amino acids which are called “essential” because they must be obtained from the diet and the human body is unable to manufacture them. They include:

7 Amino Acids

  • Isoleucine
  • Leucine
  • Lysine
  • Valine
  • Tryptophan
  • Threonine
  • Phenylalanine

Amino acids are also procured from a healthy diet, and many can be taken as an oral supplement as needed. The proteins that amino acids create are an essential part of just about every biological process in your body.

Amino acids are responsible for carrying out bodily functions and making cells such as muscles and other tissues in the body. They also help give those cells structure and play vital roles in the transference and storage of nutrients to different parts of the body.

How your organs, tendons, arteries, and glands function also depend on different amino acids. Wound healing, tissue repair, and skin and hair growth are also related to how amino acids perform in the body.

Amino acids are responsible for building and transporting many substances within the body, but they also work to remove waste and other deposits that are produced as part of the body’s functions and metabolism.

Having an appropriate quantity of the needed amino acids also helps to regulate the body’s metabolism in different ways and can prevent disease, tissue damage, organ damage, and other health issues.

Helpful Reference: Amino Acid Chart

Amino acid charts

There are many different amino acids, and the way that they can combine leads to an even more significant number of potential compounds. In addition to that, each amino acid has a 3-letter symbol, 1-letter symbol, formula, molecular weight, and structure.

Different charts present information about amino acids in different ways, and our list of amino acid charts offers a variety of different formats to suit different needs. Having an amino acid chart on hand may help save time and prevent mistakes.

DTU Bioinformatics

The amino acid chart provided on the DTU Bioinformatics website is straightforward and offers up the 1-letter symbol, and the DNA codons. It lists 20 amino acids found in proteins, along with the 64 available 3-letter symbols that correspond to each respectively.

Although this table is somewhat bare-bones, it’s easily printed and hung up where it is convenient for reference. If all you need is some basic information about amino acids, then this chart is ideal for you.

This chart may not have all of the information necessary for an introduction to the subject, but it succinctly provides essential information without frills, distracting colors, icons, or logos, and comfortably fits on one page.

Oregon State

The amino acid chart provided by Oregon State is a color-coded table that makes it possible to translate different parts of mRNA code into a sequence of amino acids. The simple 3 step directions indicate that you first need to select the nitrogenous base, and then match it to the first letter on the table.

After that, you follow the row until it leads you to the second and third letter required for the sequence, and each letter is color coded in black, blue, red, or green.

Although the table looks complicated at first, once you go through the steps a few times it becomes a rather quick way to look up an amino acid sequence without needing to do an online search each time.

The table also does a great job of narrowing down the available options, so if you are unsure of one of the bases, you can at least get an idea of what the possible options are which may be all you need to figure it out.

This table is also relatively compact, and provided you have access to a color printer it could be beneficial to have printed out and on hand for when you need it.

Sigma- Aldrich

The amino acid charts provided by Sigma-Aldrich are much more extensive and present the information in both chart and structure format. You can quickly look up the drawn structure of an amino acid complete with different side chains, or you can scroll down to the tables that have more information about the amino acid properties.

This page has a wealth of information about the amino acids and lists them in different groupings and categories for convenience. You can peruse the chart that talks explicitly about properties such as symbols, weights, molecular formula, or residue formula, and you can also view them based on how hydrophobic they are.

The bottom of the page also lists some relevant technical articles that relate to amino acids, and there is a link that allows you to read the abstracts from those papers. This website also features a wealth of other information and charts related to medical science, biology, genetic research, and life science.

What Does New Research Say About Slowing the Aging Process?

As we age, our bodies change significantly. Some of the effects of aging are quite apparent. For many, the skin loses its elasticity, the hair begins to turn gray, and mobility becomes much more challenging. It comes as no surprise that many people are looking for ways to slow and reverse the process of getting older.

But what does new research say about slowing the aging process? Is it possible? And to what degree does slowing the aging process affect the typical quality of life? In this article, we’ll look at what scientists have discovered so far in hopes of shining some light on the inevitable process of getting older.

Slowing the Aging Process

Over the past few years, there have been more than a few studies on slowing down and even reversing the aging process.  With age often comes disease and scientists are eager to cut down on the painful and expensive plights of old age. Recently a few different methods have shown promising success regarding the pace of aging.

Why We Age

To understand how researchers suggest we can slow the process of aging, one must first understand why we age, to begin with. Over the last thirty years or so, technological advances have allowed scientists to take a closer look at why we age.

In general, scientists now know that aging is controlled by genetic factors and biological process that occur naturally in the human body. More specifically, aging occurs because of the following reasons:

  • Telomere Shortening
  • Genome Damage
  • Mitochondrial Dysfunction
  • Non-Genetic Factors
  • Unfolded Protein Build-Up
  • Stem Cell Exhaustion
  • Cellular Deterioration

Slowing Down the Aging Process

But what does new research say about slowing the aging process? A continuously growing body of research has revealed that a few different techniques can be used to slow down or reverse the process of getting older. These techniques include but are not necessarily limited to the following:

  • Intermittent Fasting
  • Stress Management
  • Meditation
  • Regular Exercise
  • Positive Mental Attitude
  • Eating Healthy

What Does the Research Say?

Delving further into what scientists have to say about slowing the aging process, below we will discuss each of the age-slowing methods mentioned above. To keep things well-organized, we’ll start off with the most recent research and go from there.

Regular Exercise

Regular Exercise Slowing Down the Aging Process

Multiple recent studies have been conducted to establish any potential connection between regular exercise and longevity. In 2018, researchers confirmed that regular activity continued through the entire lifespan can decrease the chance of muscle decline in old age. Compared to their sedentary counterparts, active seniors were shown to have less age-related muscle deterioration.

Besides, regular exercise has been shown to promote the body’s immune system. A typical side effect of aging is reduced thymus size and an inability to stave off disease. Researchers found that regular cycling can cause the immune system to behave in a more “youthful” manner regarding white blood cell activity.

As a final note on regular exercise, researchers in 2017 found that vigorous activity can both promote mitochondrial capacity and increased telomere length. These two factors are essential when considering the process of aging, and both indicate that regular exercise is an excellent way to decrease the speed of getting older.

Intermittent Fasting

Intermittent Fasting

Intermittent fasting has become somewhat trendy in the diet world lately, and for a good reason. In addition to stunning weight-loss related results, a study published in late 2017 suggests that the same technique could be a critical component to extending lifespan and slowing the aging process.

This study, published by Harvard researchers in October 2017 provides useful insight into the way that cells process energy over time. Researchers in this study used nematode worms to investigate the state of mitochondrial networks across the lifespan of the organisms.

Researchers used two techniques to mimic the process of intermittent fasting in their test subjects. The first involved merely restricting diet, while the second method used manipulation of a specific “energy-sensing” protein (AMPK). Both processes showed that intermittent diet restriction has a significant impact on mitochondrial networks.

In both types of dietary restriction, researchers noted that mitochondrial networks maintained a certain “youthfulness” in that they retained their fused state. This fused state promoted communications between the mitochondria and other organelles that modulate fat metabolism.

While this is indeed not the first study to show that intermittent fasting can accommodate graceful aging, it is a pivotal step in understanding why this technique can reduce the pace of getting older.

Stress Management

7 Stress Management Tips

Stress has long been known to contribute to certain diseases such as increased blood pressure and depression. Recent research has revealed even more evidence that chronic stress is unhealthy. In particular, researchers at the University of California, San Francisco have discovered a link in constant pressure and decreased levels of klotho.

Klotho has been recognized as a link in the mysteries of aging for quite some time. Previous studies have indicated that increased levels of klotho subsequently increase lifespan in different types of animals. However, this study from 2015 is the first to present a potential link between chronic stress and significantly decreased levels of klotho.

Dipping in a little further, it becomes apparent that proper stress management is crucial to increasing overall lifespan. By mitigating stress, it is possible that klotho levels will rise and subsequently lead to a slower aging process and a longer life.

Positive Mindset

It’s always a good idea to maintain a positive mindset, but as it turns out this concept is even more crucial when considering the process of aging. This study, published in 2016, shows a critical connection between how we think about aging compared to how we age.

Researchers showed that keeping a positive mindset about aging compared favorably against mindsets that embraced the difficulties of old age. In other words, people who believed that aging would bring with it poor memory and high blood pressure would develop these ailments more readily than those who did not believe in the inevitability of a shortened old age.

This study speaks volumes to the power of a positive mindset and the ability to slow the aging process by reducing stress. Because the mind is our most powerful tool for reducing our stress, and subsequently increasing telomere longevity, it is entirely crucial to engage in activities that will promote healthy cognitive function.

Meditation

In this 2013 study of yogic meditation, researchers identified a definite link between brief daily meditation practice and an increase of telomerase activity. Also, those participating in a regular meditation practice saw a significant decrease in depressive symptoms and an increase in cognitive function.

The combined cognitive benefits and increased telomerase activity suggest that including a regular meditation practice can have incredible benefits on lifespan. As mentioned above, high-stress levels can contribute to premature aging in numerous ways. By increasing telomerase activity with meditation, cellular aging is slowed down.

By improving the daily lives of those who practice regular meditation, it can be presumed that reflection will positively contribute to the slowing of the aging process. Decreased depressive symptoms eliminate unnecessary stress and subsequently promote healthy and slow going aging.

Eating Healthy

It may come as no surprise that in addition to reducing stress and exercising regularly, eating healthy can promote a decrease in the pace of aging. Studies as recent as 2015 have continued to support healthy diet as a critical component to a long and healthy life.

Most recently, researchers have turned their focus to specific bioactive compounds that can slow down the aging of cells in the body. These compounds are typically found in fruits and vegetables and certain other foods like cacao and tea.

In previous research, scientists noted the benefits of consuming bioactive compounds for compromised populations. Recently it has been discovered that the same benefits are available to healthy adults as well. If you fuel your body with nutrient-dense foods, your cells will function well and resist the typical strains of old age.

So, what does new research say about slowing the aging process? Further research concerning the aging process mirrors what scientists have known for years. A healthy lifestyle is crucial for a long life.

While today’s studies are increasingly sophisticated in design, researchers are merely opening doors to understanding why health and longevity are so closely intertwined. In addition to the methods of promoting cellular survival mentioned above, it is important to note that genetics and social factors also impact how long we live.

In areas of the world that have the most substantial numbers of nonagenarians and centenarians, communities are thriving. These cultures enjoy all of the benefits listed above as a community and as such residents tend to live longer.

As technology continues to develop, we will undoubtedly discover more in-depth explanations regarding the process of aging. Accordingly, it is likely that we will reveal new methods to extend the lifespan of cells and further slow the aging process.

How the Human Brain Creates Memories and Processes Thoughts

It can be fascinating to wonder about the marvels of the human brain. Unlike most other animals, humans are self-aware. We can think, plan, and recall events that have happened in and around our lives. Despite our incredible capacity for thought, how the human brain creates memories and processes thoughts can still be quite a mystery.

How The Brain is Structured

 

It’s crucial, to begin with, the basic structure of the brain to start to understand how the human mind creates memories and processes thoughts. For the most part, animals all have relatively similar brain form. In this essential form, the innermost parts of the brain are the oldest in and have not changed much over years of evolution.

These inner parts of the brain control our most basic survival instincts such as breathing, resting, moving, and feeding. As you move away from the spinal cord, additional layers provide the capacity for higher thinking and better memory. In humans, our outermost layer of the brain is called the cerebral cortex, and it is incredibly sophisticated.

With such a highly developed outer brain layer we are capable of much more than the most basic survival functions. For example, humans frequently develop intricate social networks,  can retain memories for long periods of time and can experience emotions.

How We Form Thoughts

Moving forward from the underlying structure that allows for the formation of higher thinking patterns, we delve further into how thoughts are processed. The brain is composed of specialized cells known as neurons and support cells called glia.

As you probably know, neurons are the cells most commonly associated with the nervous system. However, it is important to note that without glial cells, the neurons in the brain would not be able to function at all. Many different types of glial cells exist in the brain and provide numerous benefits to the neurons.

More specifically, glial cells provide the following benefits to neurons:

  • Guide Developing Neurons to Their Destinations
  • Protect Neurons from Harmful Ions and Chemicals
  • Provide Myelin Sheaths Around Axons
  • Modulate Communication Between Nerve Cells

As you can see, these lesser-known cells are incredibly crucial to a fully functioning human brain. In fact, without these essential support cells, humans would not be capable of processing thoughts or forming memories.

Neurons are the specialized cells that receive all forms of sensory input from the external world and communicate that information to the body and brain. Compared to other types of cells, neurons have a unique tree-like shape that fosters the work of delivering information throughout the body.

While much is unknown about the inner workings of the brain, scientists have discovered that neurons behave in a pretty specific manner. There are three main parts to each neuron; the cell body, the dendrites, and the axon. When exposed to an electrical impulse, information moves from the dendrites to the cell body and then to the axon.

Once the electrical impulse moves to the end of the axon, it reaches the synapse. Here the signal moves from one neuron to the next by way of a neurotransmitter. The neurotransmitter stimulates the next neuron, and the process begins again.

When neurons absorb information from the wide variety of stimuli we come in contact with every day, billions of connections can occur through the neural pathways described above. These connections are what lead to our perceptions about the world around us. Furthermore, these connections work together to create our thoughts.

But what happens after the brain has “processed”  thought in this manner? Does it all just end there?

How We Store Thoughts

Now that we have outlined a basic understanding of how thoughts come to be, we can continue to work out how the human brain creates memories and processes thoughts. It’s important to understand that neuroscience is a very complicated discipline and is not entirely understood by researchers as of yet.

Most people understand that the process of storing thoughts is what we refer to as memory. However, a much smaller number of people have any real understanding of how our brains take seemingly “simple” thoughts and turn them into memories.

To start our discussion, we will begin by saying that memory, unlike other attributes of the body, is not a defined part of the body. Instead, the word memory refers to the elaborate means of remembering.

A wide array of models have been used to describe the way that memory works in the human brain. However, current researchers are quickly finding that these simplistic notions regarding memory are nowhere near as sophisticated or elusive as the human memory. Today, scientists are finding that it is made up of a complex web of cells placed explicitly around the brain.

Short-Term Memory

Most people have heard the term “short-term memory” at one point in their life or another. However, only a handful of people can give an accurate description of what short-term memory is.

To begin our discussion, we’ll note that short-term memory is also known as active or primary memory. As these names imply, short-term memory is something that we use in our present state of being. Furthermore, it is worth noting that short-term memory is limited in both duration and number of items held.

For most functioning brains, the short-term memory lasts between twenty and thirty seconds. Sometimes this time frame fluctuates in either direction depending upon the circumstances under which information is received. Typically the average human brain can hold between four and nine items in short-term memory.

Long-Term Memory

In contrast to the fading short-term memories that we dispose of quickly, the long-term memory seems to be unlimited regarding the number of items stored. Additionally, long-term memories are typically stored for much more extended periods of time, usually many years. But how exactly does the human brain move items from short-term memory to long-term memory?

Most people are vaguely aware that there are a variety of techniques for committing specific information to memory. For example, people tend to “chunk” information into smaller parts of a larger whole to memorize it. Also, it is common to use rehearsal as a means of committing short-term memory to long-term storage.

Despite the knowledge of these memorization methods, the specific science behind “converting” short-term memories into long-term memories is not well understood. Several working theories try to explain the precise mechanisms of memory. Each potential philosophy is unique, and this particular subject is a matter of much scientific controversy.

Memory Loss and Difficulty

It’s no secret that just as our brains have an incredible capacity to process information and develop memories, they also can “lose” memories. Injury, trauma, and certain illnesses can all affect the way we remember things and even make it seem that certain memories are gone for good. But what exactly happens when we “lose” a memory?

Because the mechanisms regarding thoughts and the way we store memories are not very well understood, it is difficult to say what precisely happens when we forget something. In some cases, memory loss seems to be temporary while in others it looks more permanent. By examining the different causes of memory loss, we can gain some useful insights.

Retrograde vs. Anterograde Amnesia

In movies that feature patients with amnesia, it’s often the case that these characters cannot remember their past. This type of amnesia is medically known as retrograde amnesia. Retrograde amnesia can be caused by disease or injury and deals explicitly with memories stored before illness or injury. The ability to learn new concepts is generally not affected.

In contrast, anterograde amnesia preserves old memories and prevents the development of new memories. Because of the mystery surrounding how the brain stores memories, anterograde amnesia is very difficult to understand. Additionally, this type of amnesia provides a wide array of questions regarding how memories are formed and stored.

Dementia and Alzheimer’s Disease

The term dementia refers to a group of diseases that cause a slow decline in the ability to think and recall past knowledge. Alzheimer’s disease is the most common disorder associated with dementia and also the most common cause of it.

Despite Alzheimer’s disease causing the majority of dementia cases, there are several other causes of dementia. Some of these causes are reversible, suggesting a high degree of plasticity in the brain. However, there is no defined cure for Alzheimer’s disease or dementia in general which highlights our general lack of understanding of the human mind.

Overall, the mechanism that dictates how the human brain creates memories and processes thoughts are complicated. Neuroscientists are continually researching new theories and challenging previous notions regarding the human mind.

As new technologies develop, scientists have high hopes of gaining a better understanding of the brain and all of its intricacies. However, until we can understand the subtle processes that create our ability to think and store information, it is unlikely that we will gain a better understanding of diseases that affect our ability to create and access our memories.
