Microscopy

Summary

The entire exercise was all about caring for and using the microscope. We performed various activities that enabled us to familiarize ourselves with the parts and uses of the microscope. Using the microscope, we observed different objects such as cotton, silk, hair, and even a letter "e." We viewed it using both the low power objective and the high power objective. We did these activities in order to better understand how the compound light microscope works and also to learn about the different procedures in setting up a slide. The results of the activity made us learn how to operate the microscope efficiently. I found out that the iris diaphragm controls the light and the uses of the LPO and HPO. I also noticed that the view of the object being illuminated is inverted.

Abbreviations

LPO- Low power objective

HPO- High power objective

Introduction

There are a lot of things not visible to the naked eye. What most of us don't realize is that there is a world full of wonders out there; A world full of diversity and "magic." A world called microscopy. It's amazing how one single device called the microscope can let us view things that are too small for the human eye. A microscope has the power to magnify object from 100x to as much as 1000x or higher. In fact, there are many microscopes, each with their own unique capability. Examples of these are the atomic force microscope, scanning probe microscope, and electron microscope. Microscopy is the technique in which a person is able to view images of structures that are too small for the naked eye. In light microscopy, light is reflected through a series of lenses that eventually illuminate the object being seen.

...th the different parts and uses of the microscope. I conclude that compound light microscopes give inverted images of the object because of the reflected light; and that the passage of this light is controlled by the iris diaphragm. I also conclude that each part of the microscope is significant for it to function properly and effectively.

    .... 'It is a moment when the visible escapes from the timeless incorporeal order of the camera obscura and becomes lodged in another apparatus, within the unstable physiology and temporality of the human body'. Crary further demonstrates the shift in vision's location from camera to body by examining the way in which it was reproduced in various optical devices invented during this same period, specifically the stereoscope, the kaleidoscope, the phenakistiscope, and the diorama. His examination is based on a provocative premise: 'There is a tendency to conflate all optical devices in the nineteenth century as equally implicated in a vague collective drive to higher and higher standards of verisimilitude' (110). According to Crary, such an approach tends to neglect entirely how some of these devices were expressions of what he calls 'nonveridical' models of perception.

    Then, when she was finished reading, she stopped at a particular line and I wrote down her results. I also tested her other eye, which is her right eye, which had different results. After, she finished and I wrote her results down, I tested her vision field by sitting in front of her and placing my finger near her ear and she then told me when she saw my finger first. Next, I tested Jazmine Cooley’s oculomotor, trochlear, and abducens nerves by looking at the pupil of her eye and briefly shining a flashlight into her eyes asking her to look up, down, left, right, and side to side. Then, I repeated the same test, however, I did not use a flashlight this time, but I had her follow along to my clenched fist with my thumb held up.

    Prior to the invention of the daguerreotype, the Camera Obscura was the main optical instrument that was used to project images onto paper. The Camera Obscura was a device in the shape of a box that allowed light, which was being reflected from the images that the user was intending to capture, to enter through an opening at one end of the box to form an image on a surface and an artist would then trace the image to form the most accurate impression of an image at that peri...

    The microscope is an advancement in technology in Chemistry since it was invented since 1959. The technology that involves Chemistry has evolved as the Chemistry that involves technology. From looking at cells 500 times greater to the naked human eye, and from looking at cells to bacteria in an animal to what goes on in a plant and how it absorbs light, the microscope can change the world in just a second when a new discovery is made. People has come very close to discovering a cure from cancer but all the times it has failed time and time again A cure for someone who needs a cure for cancer can happen in a moment with the help of the microscope and the necessary resources. Once people look at life through a microscope, there is no stopping or telling on how many discoveries and cures we can find.

  • Eye Movement Research

    1418 Words  | 3 Pages

    Psychologist Raymond Dodge and his student T.S. Cline developed the first camera-based technique for registering eye movement in 1901 [3]. They used a falling plate camera (also referred to as a photo-chronograph) to measure light reflected from the cornea. However, their method required the subject’s head to be motionless and was only capable of recording horizontal eye movement. Only a few years later, motion picture photography was applied to record eye movement. This technique was useful because it allowed for a frame-by-frame analysis of the eye’s movement allowing for quantitative research on a solid basis**.

    The iris acts to control the size of the pupil. In bright light, the iris is dilated in such a way as to reduce the size of the pupil and limit the amount of entering light. In dim light, the iris adjusts its size as to maximize the size of the pupil and increase the amount of incoming light.

  • Cataracts And Surgery Essay

    1037 Words  | 3 Pages

    The human eye is one of the most complex organisms in the human body and the lens is one of the most impressive structures within it! Despite being slightly over two centimeters in diameter, the human eye has over two million moving parts. Sight is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. The lens is a key component of the eye which, coupled with the cornea, focuses images onto the retina. This is easily achieved by the lenses biconvex shape, refractive index, clarity, and youth. In our younger years we have the ability to bring near objects into focus by the act of accommodation. Ciliary muscle shortening allows the lens to take on a more curved shape. Human vision can be limited by the optical quality of the eye, especially by the presence of a cataract. Cataracts are a very common age-related visual problem and the number of cataract operations performed is continuously on the rise; approximately 20 million surgeries were performed in 2010.

  • Eye Evolution Essay

    2260 Words  | 5 Pages

    An inspection of the modern animal phyla will reveal that eyes are just as diverse as they are complex. Some organisms like the rag worm have pigmented cup eyes while other like he box jellyfish have two lens eyes and two pairs of pigment pit eyes. To account for the diversity in eye structure, we must first examine the eye ‘prototype’, the original structure that was acted upon by evolution. The simplest organ that can be considered an eye is composed of a single photoreceptor cell and a single pigment cell, without any lens or other refractive body (Arendt, 2003). Such organs are know as eyespots, and...

  • How Can Images Improve Medical Workflow?

    Before the discovery of X-rays in 1895, it was impossible to look inside human body, without causing harmful side effects. The famous quote of Anna Bertha Ludwig - “I have seen my death” is a testimony to this. In ancient times, the only way to study internal human organs was the dissection of dead bodies. Additionally, this was also subject to availability or religious beliefs. Leonardo da Vinci made 240 detailed sketches between 1510 and 1511, which were way ahead of their time. Unfortunately, it could not be published, except for a small amount in 1632. Images aide in visualization of illnesses (e.g. a malignant tumor), which are impossible to observe from outside of the body. A surgeon must know the various attributes of the tumor like location and size, before she can operate on it. Similarly an oncologist needs this information to decide the course of treatment e.g. tumor size and metabolic activity may be needed to determine the number of chemotherapy sessions. With images, all this information can be obtained without cutting open the patient. And what’s remarkable is that u...

  • Essay On The Blind Spot

    770 Words  | 2 Pages

    In the late 1660’s a scientist, Edme Mariotte, discovered the “blind spot’ in the eye. Edme noticed a hole in the eye , the optic disc, with a nerve going through it and found that it was the blind spot. Edme is the first remembers scientist to discover the blind spot. He is often remembered for his study of optics and color perception. Edme made many more discoveries in the science fields. Although Edme did not believe the blind spot was in the retina, he was the first scientist to recognize there was something weird in the eye, at which at some point you could not see an entire image, also known as the blind spot. In the vision field the blind spot is call “Mariotte’s Spot” (Edme Meriotte (1620-1684): Pioneer of Neurophysiology, n.d.).
