Features to label in your illustration |
 |
1. (slide 2) Simple squamous epithelium, (VE:11):
top view of peritoneum, a serous membrane (an example of mesothelium,
derived from mesoderm). It functions where a slick friction-free surface
is required, or ready exchange across membranes is essential: lung alveoli,
capillary endothelium, kidney glomerulus |
cell borders
nucleus
nucleolus
tiled appearance (its heterogeneity is due to variations in sample
preparation) |
 |
2. (slide 3) Simple cuboid epithelium, (VE:257)
section of kidney. In the cortex (outer portion) of the section, view the
proximal convoluted tubules with brush borders. |
proximal convoluted tubule
basement membrane
nuclei
lumen
brush border (only on proximal convoluted tubules) |
 |
3. (slide 4) Simple columnar epithelium, (VE:13)
c.s. of the intestine of a Nectarus (a newt).
Note the classic
four functional layers of a GI wall, inside to outside: mucosa, submucosa,
muscularis, and serosa. |
basement membrane
brush border
nuclei
goblet cells
lamina propria (connective tissue which underlies mucous membrane)
capillaries in lamina propria (lacking in epithelium) |
 |
4. (slide 5) Stratified squamous epithelium,(VE:17)
dog esophagus. This tissue is especially resistant to friction. Note the
mucous alveoli of the esophageal glands. |
basement membrane
basal cells (brownish cells along basement membrane where mitosis occurs)
squamous cells being shed (superficially, include nucleated surface
cells)
lamina propria |
 |
5. (slide 6) Pseudostratified ciliated columnarepithelium,
c.s. of trachea , (try slide 11 if the detail is poor) (VE:15) This tissue
is especially prominent in the respiratory tree. |
basement membrane
numerous nuclei in deeper half of the tissue
goblet cells
cilia (contrast with brush border for appearance & function)
lamina propria |
