Lab 1-Endothelial Cells

what is the function of epithelium

cover body surfaces

simple squamous epithelium is

single layer of flat cells

on the apical surface, there may be

cilia, microvilli, and sterocilia

epithelium function is to

cover surface, line cavities, and form glands

t/f epithelium has a basement membrane

true

cilia

motile process

microvilli

short finger like projections

stereocilia

long microvilli

simple epithelium

single layer of cells

stratified epithelium

two or more layers of cells

squamous

flat

cuboidal

short and square (cube)

columnar

rectangle (column)

What is the structure of pseudostratified columnar epithelium?

It is a simple epithelium that appears multilayered but is not, with nuclei at different levels but all cells attached to the basement membrane.

What is the defining characteristic of pseudostratified columnar epithelium?

The nuclei of its cells are at different levels, giving the appearance of multiple layers, but all cells are attached to the basement membrane.

transitional epithelium

only in urinary system, stratified

cells change based on fluid pressure

empty bladder transitional cells become

domed

full bladder transitional cells become

flat
