Epithilium

epithelium /ep·i·the·li·um/ (-the´le-um) pl. epithe´lia [Gr.] the cellular covering of internal and external body surfaces

1

Tissues

an aggregation of similarly specialized cells which together perform certain special functions

2

Basement membrane

a thin layer of tissue that covers a surface, lines a cavity, or divides a space or organ

3

Apical surface

the layer of plasma membrane on the apical side (the side toward the lumen) of the epithelial cells in a body tube or cavity

4

Goblet cells

any of the protoplasmic masses making up organized tissue, consisting of a nucleus surrounded by cytoplasm enclosed in a cell or plasma membrane.

5

Secretion

the cellular process of elaborating and releasing a specific product; this activity may range from separating a specific substance of the blood to the elaboration of a new chemical substance.
