A

Allows materials to pass by diffusion and filtration in sites where protections is not important. secretes lubricating substances.

Q

What is the function of simple columnar epithelium?

A

Absorption, secretions of mucus + enzymes, etc. ciliated type propels mucus or reproductive cells by ciliary action.

Pseudostratified columnar epithelium

24
Q

Single layer of cells of differing heights, some not reaching the free surface, nuclei seen at different levels, may contain mucus secreting goblet cells or bear cilia

A

Pseudostratified columnar epithelium

25
Stratified squamous epithelium
26
Thick membrane composed of several cell layers, basal cells are cuboidal or columnar and metabolically acive, surface cells are flattened. keratinized: surface cells are dead and full of keratin. basal cells produce the cells of the superficial layers via mitosis.
Stratified squamous epithelium
27
Stratified cuboidal epithelium
28
Generally two layers of cubelike cells
Stratified cuboidal epithelium
29
Stratified columnar epithelium
30
Several cell layers, basal cells usually cuboidal superifical cells elongated and columnar.

Transitional epithelium
32
Resembles both stratified squamous and stratified cuboidal depending on degree of organ stretch
