epithelial tissues Flashcards
epithelial tissue
covers and protects, function varies, little matrix
lumen
free surface
epithelia
reproduce quickly
simple squamous (structure)
single layer of flat cells
simple squamous (function)
allows materials to diffuse through quickly
simple squamous (location)
found in alveoli and capillary walls
simple cuboidal (structure)
single layer of cube shaped cells
simple cuboidal (function)
offers some protection, more relevant when substances are secreted and absorbed
simple cuboidal (location)
found in covering of ovaries
simple columnar (structure)
single layer of tall cells
simple columnar (function)
offers some protection of underlying tissue where secretion occurs
simple columnar (location)
lining of stomach
goblet cells
make mucus
cilia
microhairs
pseudostratified columnar (structure)
appears to be stratified but is not
pseudostratified columnar (function)
offers protection in places where mucus is secreted
pseudostratified columnar (location)
found in trachea and sperm ducts
stratified squamous (structure)
thick and multilayered with flat surface, cuboidal and columnar at basement
stratified squamous (function)
protects against friction
stratified squamous (location)
found in outer layer of skin and esophagus
transitional epithelium (structure)
several specialized layers
transitional epithelium (function)
can be stretched in response to tension
transitional epithelium (location)
found in urinary bladder and uterus
