Q

What are the general features of epithelial tissue?

A

1.closely packed cells.
2. Arranged in sheets. (Layers) that may be 1 cell thick or many cells thick.
3. Has an apical surface(upper) and a basal surface(bottom)
4. Has lots of cell junctions to hold cells together.
5. Avascular-no blood vessels in epithelial tissue.
6. Attached to connective tissue by basement membrane has two parts
A. Basil lamina made by epithelial cells.
B. Reticular lamina- made by connective tissue
7. Has a nerve supply, nerve endings can get in between cells of basal surface.
8. Can do lots of cell division, allows tissue to renew.

A

Simple columnar epithelium

17
Q

Which type of epithelial tissue is used for secretion and absorption? Ex- kidney tubules.

A

Simple cubodial epithelium

18
Q

Which type of epithelial tissue is simple columnar epithelium with some cells shorter than others, looks like multiple layers but isn’t. Lines some of the respiratory tract, often ciliated.

A

Pseudostratified epithelium

19
Q

Which type of epithelial tissue is more flat at the apical surface less flat at the basal surface. Forms thick barriers for protection. Ex- epidermis in skin.

A

Stratified squamous epithelium

20
Q

which type of epithelial tissue is for protection in the urethra?

A

stratified columnar epithelium

21
Q

which type of epithelial tissue is in the salivary glands for secretion?

A

stratified cubodial epithelium

22
Q

which type of epithelial tissue is in bladder? cells can change shape and rearrange layers to stretch.

A

transition epithelium

23
Q

which type of epithelium is modified to secrete fluid?

A

glandular epithelium

24
Q

what is multicellular glands?

A

glands that are made of many cells, the gland grows into connective tissue

25
Q

which type of gland is only one cell that secretes fluid? ex. goblet cells secrete mucus.

A

single cell gland

26
Q

which type of gland secretes fluid into duct?

A

exocrine glands

27
Q

which type of gland secretes hormones into blood (no duct)

A

endocrine glands
