Question 10

What are the general features of epithelial tissue?

Answer 10

1.closely packed cells.
2. Arranged in sheets. (Layers) that may be 1 cell thick or many cells thick.
3. Has an apical surface(upper) and a basal surface(bottom)
4. Has lots of cell junctions to hold cells together.
5. Avascular-no blood vessels in epithelial tissue.
6. Attached to connective tissue by basement membrane has two parts
A. Basil lamina made by epithelial cells.
B. Reticular lamina- made by connective tissue
7. Has a nerve supply, nerve endings can get in between cells of basal surface.
8. Can do lots of cell division, allows tissue to renew.
