E.g. intervertebral discs, symphyes
Wha type of collagen does white fibrocartilage contain
Type 1 and type 2 collagen
Where is elastic cartilage found
Found in pinnacle of ear -keeps tubes permanently open
How is the structure of elastic cartilage different to hyaline cartilage
Contains elastic bundles scattered throughout the matrix
Where is hyaline cartilage found
On joint surfaces
Synovial joints
Sternum
What happens when pressure is applied to hyaline cartilage
When pressure is placed on the cartilage- water leaves then returns to original shape
