2 kinds of mesothlium

A
  1. peritoneum
  2. pericardium
31
Q

simple cuboidal epithelium

A

single layer of cells that are as tall as they are wide with a centered located nucleus

32

where is simple cuboidal epithelium found

A

ovary, capscule of the lense of eyes, kidney tubules, smaller ducts of glands, secreting portion of some glands like the thyroid

34
Q

Noncilliated simple columnar epithelium

A

cells are taller then they are wider, single layer, nucleus is near the base of the cell

35

2 types of Noncilliated simple columnar epithelium

A
  1. goblet cells
  2. absorptive cells
36
Q

Goblet

trachea, epidermis (found in male), urethra

46
Q

function Pseduostratisfied columnar epithelium

A

secrets and movement of mucas by ciliary action

47
Q

Stratified epithelium

A

stratified names depend on the shape of the cell in the apickle layer only

48

A

urinary bladder, uritter, urethra, uterus

62
Q

what is the function of transitional

A

distension (promits organs to stretch rupturing)

Endocrine gladualr (ductless glands)

A

hormones= secretory product

65
Q

The function of endocrine glandular

A

the products diffuse into blood after passing through interstitial fluid without going through a duct

66
Q

Where is endocrine glandular found

A

thyroid, adrenal, pituitary
