Epithelial Flashcards
Simple Cuboidal
Kidney tubules and ducts of some glands (salivary, thyroid, pancreas, liver)
Simple Columnar
Lines uterus/fallopian tubes, stomach and intestines
Psudostratified Columnar
Upper respiratory tract (trachea, bronchi, bronchioles)
Stratified Squamous
Outer layer of skin, mouth, throat, vagina, anal canal
Stratified Cuboidal
Mammary glands, sweat glands, salivary glands, and pancreas
Stratified Columnar
Vas deferens, pharynx, junction of distal esophagus and cardiac sphincter
Transitional
Urinary bladder
Elongated cells, nuclei on basement of membrane, microvilli, cilia
Absorber and cilia moves things
Simple columnar
Single, thin, flat, permeable
Good for diffusion
Simple squamous
Single, cube-shaped, central nuclei, single ring
Secretion & absorption
Simple cuboidal
Looks like more than one layer but it’s not, nuclei not all on bottom, cilia, goblet cells
Sweep debris, goblet cells produce mucin
Psudostratified columnar
Flattened layerS of cells
Wear and tear, friction, exposure, protect from fluid loss and invasion
Stratified squamous
2-3 layers of cuboidal
Great protection, secretors
Stratified cuboidal
Several layers of columnar
Very rare in the body
Stratified columnar
Designed to return to normal size
Transitional
