Flashcards in lab 8- epithelial cells (test 1) Deck (8):
1

stratified cuboidal epithelium

2-3 layers, cube shaped cells
function: protection, secretion
location: mammary glands, sweat glands, salivary glands and pancreas

2

stratified columnar epithelium

superficial layer of elongated cells, basal layer of cube shaped cells
function: protection, secretion
location: male urethra and parts of pharynx

3

transitional epithelium

many layers, cube shaped and elongated cells, thinner layers when stretched
function: distensibility, protection
location: urinary bladder and ureters and parts of the urethra

4

simple squamous epithelium

single thin layer, flattened cells
function: filtration, diffusion, osmosis, secretion
location: air sacs, walls of capillaries, linings of blood vessels, and ventral body cavities

5

simple cuboidal epithelium

single layer, cube shaped cells
function: secretion, absorption
location: surface of ovaries, linings of kidney tubules, linings of ducts of some glands

6

simple columnar epithelium

single layer, elongated narrow cells, some ciliated
function: protection, secretion, absorption
location: linings of uterus, stomach, gallbladder, and intestines

7

pseudostratified columnar epithelium

single layer, elongated cells, some cells do not reach free surface, often ciliated
function: protection, secretion, movement of mucus and substances
location: lining of respiratory tract

8

stratified squamous epithelium

many layers, top cells flattened, keratinized surface cells of epidermis
function: protection, resists abrasion
location: epidermis of skin, linings of oral cavity, esophagus, vagina and anal canal
