elastic and collagen
describe fibrocartilage
alternating layers of hyaline cartilage matrix and dense bundles of collagen fibres
where is fibrocartilage found
in joint capsules, ligaments, tendons, insertions and intervertebral discs
fibrocartilage strenght
strongest type of cartilage
what happens to cartilage with age
water content decreases
shock absorption decreases
decreased protection of articular surfaces
