Histology
Purpose: What is the purpose of this exercise? The purpose of this exercise is to become more familiar with microscope and slides through observations of tissues. By looking at so many slides I am now much more comfortable at identifying some basic structures. The tissue slides were very important to my understanding of the tissue's function. By looking at the dense regular tendon I can see how supportive it is because of all of the fibers present. It connected what I had read and studied to an actual picture and that helps with memorization and understanding.
Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken. There are no safety concerns with this exercise.
Exercise 1: Epithelial Tissue Data Table 1- Epithelial Tissue Observations
TISSUE TYPE
OBSERVATIONS
Simple Squamous Can see round nuclei, epithelial cells don't appear squamous, very close together
Simple Cuboidal SImilar in size, encircle white spaces, spaces are different sizes
Simple Columnar (stomach) Different sizes, taller than wide, can see basal and apical surface but no featuers
Simple Columnar (duodenum) Columnar cells, brush border, basement membrane, goblet cells, connective tissue,
Stratified Squamous (keratinized) Cells different sizes, dark keratinized layer at surface, lighter layer of living cells with basement membrane separating it from connective tissue. Basement membrane is wavy.
Stratified Squamous (non-keratinized) cells look flat, could see nucleus in a few, seemed to be layered
Pseudostratified Ciliated Columnar can see cilia, cells rounder near basement, and look longer and stretched near surface
Transitional Roundish cells, could see some binucleat cells, can't view slide as closely as book/web so cells look more spread out
Stratified Cuboidal (online) 2 distinct layers, round cells above a layer of more oval cells. Round cells about the same size and oval
