Magnification

Then, the sections were dehydrated in xylene before being mounted with Neutral Balsam. Five transverse sections from each animal were picked out and 3 vision fields randomly selected per section. They were then photographed under 20X magnification using the Nikon TE-300 microscope. The number of neuronal cells per field was counted on the anterior horns as well as the neurons with a well defined nuclear and cell body rich in endoplasmic…

This lab was very helpful because it taught several important procedures needed in many fields. Basically, this lab taught us the proper general protocol to use to obtain and grow the microorganisms we took from the inside of the human mouth. It taught us how to properly stain and mount the samples we grew. Of course it taught us how to view our stained specimen under a light microscope. Grow the microorganisms we obtained was the first part of the lab. What we used to culture our…

This 69 year old man lives alone, this can lead to feelings of isolation but this is common with 25% of those 65-75 living alone rising to 49% of all people aged over 75 living alone. He has been treated for diabetes for 15 years and takes insulin and metformin and has had two heart bypass operations, 20.8% of men 65-74 have ischemic heart disease in the UK (ONS, 2015). The patient's mobility is poor and a mobility scooter/electric chair is used for most trips, there are estimated to be 300,000…

force on Kimaui, once he reached him he flipped him over and launched him to the air and turned to human form, he started creating a long spear made of water that was so sharp to where the point of the spear couldn't be seen even by the strongest magnification known to humans. He launched the spear at Kimaui that started descending from the air, the spear hit Kimaui with so much speed and power that he started to go with the direction of the spear and not to the ground, the water barrier made…

We then added 1 drop of our yeast culture to the groove of the hemacytometer. We focused the grid under 100X total magnification, Using the 25 large boxes that I observed, each one consisted of 16 smaller boxes in 4x4 pattern. In order to view an individual box, we had to focus at 400X total magnification. We then counted a 5 large box and recorded the observed number of cells in each box by using the counter. We will show you how how we used the direct count…

A light microscope works like a telescope using glass lenses to reflect light, which magnifies images which are naked to the human eye such as cells and dust. The lens closest to your eye is called the eyepiece lens. This usually has a magnification of x10. Objective lenses are lenses of several different strengths which magnify the image. The stage is the place where the microscopic slide sits. This is held in place by the clips. The light source (can be a mirror or a bulb) projects light onto…

different slides and coverslips. Using the surface pipet, take a small sample of pond water form the surface and place one drop on the slide. Place a coverslip on it and then examine under the microscope. Using the objectives, switch to higher magnifications to observe details. Record the observations and using the dichotomous key, identify each type of organism. Repeat the same steps for the middle and…

‘Dental implantology is the field of dentistry that is concerned with the replacement of missing teeth and their supporting structures with artificial prostheses anchored to the jawbone (Association of Dental Implantology, 2012).’ It is an excellent way of replacing missing teeth without damaging the neighbouring teeth as done in the case of fixed bridgework. The success of dental implants largely depends on appropriate case selection. To formulate an appropriate treatment plan, the following…

Electron microscope (Manning, n.d.) is the instrument used to magnify different scientific artifacts with the used of electron beams to create the illustration of the sample, and has the capacity to magnify two million times of the original specimen. The development of the electron microscope was first known in the year 1931 because Ernst Ruska and Maximoll Knoll magnified electron image successfully, but the equipment was actually constructed in 1933 (Innes, n.d.). The concept of the electron…

Galileo Galilei was born on February 15, 1564, in Pisa, Italy. He was the first of six children born to Vincenzo Galilei, a well-known musician and music theorist, and Giulia Ammannati. In 1574, his family moved to Florence, where Galileo began his formal education at the Camaldolese monastery in Vallombrosa. Galileo Galilei is remembered for several things but one in particular was making observations that essentially set the foundation for modern physics and astronomy. Galileo was never…
