Histology quiz Flashcards
simple squamous epithelial function
-passive diffusion and filtration (gas exchange in lungs)
-secretes lube (pericardial cavity)
simple squamous location
-alveoli of lungs
-lining of heart
simple cuboidal epithelium function
-secretion (sweat glands, secreting oil in face, saliva)
-absorption (water and salt in kidneys)
simple cuboidal epithelium location
-sweat or saliva gland lining
simple columnar function
-absorption (if no cilia)
-secretion of mucus (if goblet cells)
-CILIATED: propels mucus upward
simple columnar function IMPORTANT
have cilia at apical surface.
if has goblet cells, has cilia.
non ciliated simple columnar location
digestive tract
ciliated simple columnar location
lines small bronchi
pseudostratified columnar epithelium function
secretion and propulsion of mucus
non ciliated pseudostratified columnar epithelium location
ducts of male reproductive tubes
ciliated pseudostratified columnar epithelium
lining of trachea and most of upper respiratory tract
stratified epithelia…
regenerate from BELOW
are named according to cells at top
stratified squamous epithelium function
thickest epithelial tissue- adapted from abrasion
keratinized and non keratinized
protection from abrasion
stratified squamous epithelium location
keratinized- anywhere on epidermis
non keratinized- inside lining of mouth
transitional epithelium function
stretches and allows stretching (of urinary bladder)
