Properties
|
component of skeletal system.
arises from embryonic mesenchyme. specialized CT for rigidity and enduring stress avascular |
|
|
composition
|
cells
ground substance fibers |
|
|
cellular components
|
fibroblasts
chondroblasts chondrocytes |
|
|
fibroblasts
|
outer layer collagen secreting cells
dense CT capsule around developing cartilage - perichondrium |
|
|
chondroblasts
|
cartilage forming cells. differentiated from chondrogenic cells
secrete ground substance called chondroitin sulphate become chondrocytes when they become trapped by own secretion |
|
|
chondrocytes
|
occupies lacuna within ground substance
mitotic but form cell nests. cartilage therefore has to grow by interstitial growth |
|
|
ground substance
|
contains cartilage primary but varies depending on type. appears amorphous
|
|
|
fibers
|
forms meshwork embedded in ground substance. vaires depending on cartilage type
|
|
|
cartilage growth methods
|
appositional growth
interstitial growth |
|
|
appositional growth
|
growth at surface caused by proliferation of chondrogenic cells into chondroblasts. grow at the surface, enlarges layer by layer because of deposition of new cartilage
|
|
|
interstitial growth
|
growth from within (swells)
|
|
|
Cartilage types
|
hyaline
elastic fibrocartilage |
|
|
hyaline
|
found on end of bones in synovial joints
|
|
|
elastic
|
numberous elastic fibers
found in earlobes and larynx. won't calcify, very resilient |
|
|
fibrocartilage
|
many fibers, few cells. Areas under great pressure
