Cards

Term
What do epithelial tissues do?
Definition

cover body surfaces and line body cavities

 

-form most glands

-retain mitotic ability (reproduce)

Term
apical surface
Definition

surface of epithelial cell that is exposed to the body exterior or to the cavity of an internal organ

 

-"free surface"

-has microvilli

-can also have cilia (hair)

Term

microvilli

function?

Definition

projections from the plasma membrane to help increase surface area in epithelial tissue

 

-located on apical surface

Term
basal surface
Definition

surface of epithelial tissue in contact with the structure that the epithelial tissue is covering or lining

 

-within basal surface is basement membrane

 

Term

basement membrane

functions?

Definition

extracellular material secreted by epithelial cells

 

-on basal surface

-attach the epithelial cells to underlying tissue

-support and guide cell migration during tissue repair

Term
what are the specific functions of epithelial cells?
Definition

-protection (skin)

-secretion (sweat glands)

-absorption (intestinal mucosa)
