Book: Zooming in

This chapter within the book features parts of the human anatomy that has been been looked at under various microscopes at magnifications of 100x and above. This gives me a rough scope as to what human cells and tissues can look like under microscopes at various magnifications.

Below is an image of the largest nerve in the human body, the Sciatic nerve. This nerve goes down the thigh and leg from the hip. The gray parts are nerve fibers which are separated by curving strands of connective tissue (black parts). 700x

The outer layer of the tongue can be put under the microscope also. Taste buds are the dark parts and muscle tissue is the light areas. The tongue is made up of many small bumps called Papillae, which contain the never to help us to taste food. 375x

The human lip is also a good are to focus on since it contains a vast supply of blood muscles and vessels. Black areas are the muscles and the gray areas are the blood vessels and connective tissue.

Although some of these areas are highly risky to reach and would mean cutting my open and digging around to then take samples of cells and tissues, blood is more easily obtainable, and has the least risk factor. Among this chapter is a sample of blood under the microscope at 1,200x. Among this sample is all the red cells accompanied by a few white blood cells.
