What are the functions of Epithelium?
- -protection
- -secretion
- -absorption
- -exchange/filtering
- -transport
- -sensory reception
- -contractility
- -reproduction
-
What type of cell shapes?
- Squamous: flat, width > height
- Cudodial: appear square
- Columnar: height > width
- Transitional: alter shape
-
What types of cell layers?
- -simple epithelium: one layer, blood vessels
- -stratified epithelium: two or more layers, skin
- -pseudostratified: one layer, but nuclei are at different heights, trachea
-
What are the specializations?
- -Cilia - long, motile projections, longer than microvilli, found in RESPIRATORY TRACT
- -Goblet Cells - secretion purposes
- -Microvilli - increase surface area, intestines
-
Simple Squamous
- single layer, found in heart, blood vessels and lymph vessels
- function is secretion protection and absorption
-
Simple Cuboidal
- occurs in excretory ducts of many glands, thyroid gland, tubules of kidney
- function is seretion absorption and reproduction
-
simple columnar
- found in uterus, stomach, intestines
- function is secretion, absorption, protection
-
stratified squamous
- outer layer of skin, mouth, throat, vagina, anal canal
- function is protection
-
stratified cuboidal
- found in mammary glands sweat glands, salivary glands
- function is protection
