Epithelium Cells Flashcards
List different defining features of epithelium cells.
1) usually covers organ surface
2) One or more layers of contagious cells
3) sparse extracellular material
4) avascular
5) anchored to the basement membrane
6) basal, apical, and lateral membrane
7) Adjacent to loose connective tissue
Which epithelium cell shape is flat, scaley, and looks like a fried egg?
squamous
Which epithelium cell shape has an approximately equal height and width?
cuboidal
Which epithelium cell shape consists of tall, narrow cells?
columnar
Which kind of epithelia has a single layer of cells where all cells touch the basement membrane?
simple epithelia
Which kind of epithelia has two or more cell layers (with some resting atop others) and there is no basement membrane?

- usually ciliated
- looks more disorderly
- few/no nuclei to register
- looks like many layers
