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.

16
Q

Which type of epithelial tissue is absorption of nutrients and secretion(mucus). Ex- small intestine

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
what is multicellular glands?
glands that are made of many cells, the gland grows into connective tissue
25
which type of gland is only one cell that secretes fluid? ex. goblet cells secrete mucus.
single cell gland
26
which type of gland secretes fluid into duct?
exocrine glands
27
which type of gland secretes hormones into blood (no duct)
endocrine glands
