|
Epithelial
|
Covers all body surfaces, lines organs, forms glands
closely packed with tight junctions Avascular but has nerve supply |
|
|
Connective
|
protects, binds, and supports organs, stores fats
have nervous and blood supply ( except cartilage) |
|
|
Muscles
|
skeletal, smooth, cardiac
|
|
|
Nervous
|
central & peripheral
|
|
|
Simple Squamous
|
minimal barrier to diffusion of gases or electrolytes
alveoli, endothelium of capillaries and kidneys |
|
|
Simple Cuboidal
|
thicker than squamous, less diffusion
usually for secreting substances in glands and absorption |
|
|
Simple Columnar
|
May contain microvilli- increase surface area
(GI tract) May contain cilia- tiny hairs (upper respiratory tract, falopian tubes) thicker for less passive diffusion |
|
|
Connective Tissue Matrix
|
fibers- collagen, elastin
ground substance- chemicals that lubricate, support and connect cells |
|
|
fibroblasts
|
secrete matrix
|
|
|
macrophages
|
destroy bacteria
|
|
|
plasma cells
|
secrete antibodies
|
|
|
mast cells
|
alongside blood vessels, secrete histamine
|
|
|
where is collagen found?
|
cartilage, tendons, ligaments, and bones
|
|
|
Loose CT
|
fibers are loosely woven, contain all the types of cells, Fills intracellular spaces
|
|
|
Reticular CT
|
provides support for capillaries, nerves, muscle cells
|
|
|
Dense Irregular CT
|
same as loose CT, but more collagen and fewer cells, elastic
|
|
|
Dense Regular CT
|
lots of collagen, forms tendons and ligaments, strong in only one direction
|
|
|
Cartilage
|
very strong but flexible, gel like. No blood vessels
|
|
|
Bone
|
compact and dense. Matrix contains inorganic calcium salts. Can absorb heavy metals
|
|
|
Blood
|
Plasma serves as a liquid matrix
|
|
|
Adipose Tissue
|
energy storage , cushioning, insulation
|
|
|
Skeletal
|
striated and voluntary
- attached to bones - aids in movement |
|
|
Cardiac
|
striated and involuntary
contracts the heart connected by intercalated discs |
|
|
Smooth
|
non striated and voluntary
GI , Bladder, Blood Vessels For propulsion |
|
|
Nervous Tissue
|
Transmits electrical impulses
Neurons : cell body, dendrites, axon |
