Epithelium cells
|
form the body's surfaces and cavities; covers things
|
|
|
Simple Squamous Epithelium
|
look like flattened floor tiles; only one cell thick
line the heart cavities and internal surfaces of blood and lymph vessels, the air cells of the lungs, filtration capsules and thin tubules in the kidney, and body cavities (mesothelia) |
|
|
Simple Epithelium
|
barries that are only one cell thick
|
|
|
Simple Cuboidal Epithelium
|
look like square barriers; only one cell thick
generally secretory cells make up glands, tubules of the kidney, terminal broncholes of the lungs,and ducts of the reproductive tract |
|
|
Simple Pseudostratified columnar epithelium
|
"fake layers"
looks like a multi-cell barrier, but is only one cell thick lines the tissue lined ducts of the reproductive tracts and air conduction pathways of the respiratory tracts sometimes have cilia on free surfaces and contain unicellular goblet-shaped secretory cells. |
|
|
mesothelia
|
the major body cavities
|
|
|
apical
|
free surfaces of simple columnar epithelium cells
|
|
|
basement membrane
|
a dense mat of extracellular matrix to which cells at the base of the barrier are attached
|
|
|
goblet
|
secretory cells
|
|
|
pseudostratified
|
"fake layers"
|
|
|
keratin
|
a scleroprotein that is found in the surface cells of the skin
|
|
|
transitional cells of stratified epithelium
|
cells that retract or expand depending on contense and pressure; empty retract, filled expand
|
|
|
myoepithelia
|
specialized contractile epithelial cells that encourage discharge of the glandual material
|
|
|
exocrine
|
glands that arise as outpocketings; they put out their materials through tubes
|
|
|
endocrine
|
directly inject their secretions through and into the bloodstream
|
|
|
fibroblasts
|
secrete the fibers and ground substance of the loose, areolar conncective tissue
|
|
|
macrophages
|
engulf cell debris, foreign matter, and microorganisms
|
|
|
fat cells
|
store lipids
|
|
|
adipose tissue
|
large numbers of fat cells
|
|
|
plasma cells
|
secrete antibodies in reponse to infection
|
