Describe five general characteristics of epithelial tissue.
1. Polarity - an apical surface that is distinct from the basal surface.
2. Specialized contacts so cells fit closely together.
3. Supported by connective tissue (basement membrane).
4. Avascular but innervated.
5. Easily regenerated.
How are epithelial tissues classified?
cell shape, arrangement, and relative number of layers.
