4 primary types of tissues
|
epithelial, connective, muscular, neural
|
|
|
Functions of epithelial tissue
|
Provides physical protection
Control organ permeability Provide sensation Produce secreation |
|
|
2 classifications of covering epithelia
|
Simple- only one layer of cells
Stratified- several layers of cells |
|
|
3 classifications of epithelia cells based on apical surface
|
Squamous- thin flat cells
Cubodial- Height equal to width Coulumnar- height several times width |
|
|
Simple squamous Epithelium
|
1 layer thick, shaped like plates
Function- friction reduction, passive transport location: lung aveoli |
|
|
Simple Squamous Epithelium
|
Location- lining serous membrane, lining of heart & blood vessels, lung aveoli, thin part of kidney
|
|
|
Stratified Squamous Epithelium
|
several layers thick, thin flat cell
Functions; protection from abrasion, protection from chemical & biological agents |
|
|
Stratified Squamous Epithelium
|
Location- epidermis, mouth, throat, esophagus, rectum anus and vagina
|
|
|
Simple Cubodial Epithelium
|
1 layer thick, cube shaped in cross section; functions- absorption & secretion, limited protection
|
|
|
Simple Cubodial Epithelium
|
Locations- glands(salivary, pancreas, thyroid), small ducts of glands, kidney tubules
|
|
|
Stratified Cubodial Epithelium
|
Several layers thick, cube shaped
Functions- provides a robust lining, limited secreation/absorption |
|
|
Stratified Cubodial Epithelium
|
Location- this is pretty rare, large ducts of exocrine glands, mammary glands, sweat glands, salivary
|
|
|
Simple Columnar Epithelium
|
single layer, column shaped
Functions- absorption/secretion, some protection |
|
|
Simple Columnar Epithelium
|
Location- lining of middle part of digestive tract, stomach & intestines (to rectum), collecting ducts of kidneys, gallbladder, uterine tubes
|
|
|
Stratified Columnar Epithelium
|
Functions- protection (robust lining)
|
|
|
Stratified Columnar Epithelium
|
Locations- This is also pretty rare
same places as stratified cubodial, large ducts of glands, male urethra |
|
|
Pseudostratified Ciliated Columnar Epithelium
|
Functions-absorptions/secretion, some protection, movement of mucous, etc.
|
|
|
Pseudostratified Ciliated Columnar Epithelium
|
Location- lining of respritory tract (nasal cavity, trachea, bronchi) male reproductive tract
|
|
|
Transitional Epithelium
|
Function-Stretching
Location- urinary tract, bladder, renal pelvis ureter |
|
|
Merocrine
|
Secretory vessicles only
|
|
|
Apocrine
|
Secretory vessicles and apical part of cell
|
|
|
Holocrine
|
Entire cell rupture
|
