Ossification the the process that occurs when cartilage is replaced by bones!
Elastic or Yellow Cartilage is the typical cartilage present in external or outer ear. It contains elastic and collagen fibres with elastin as major protein.
Collagen is a protein that provides strength and flexibility in the bone, cartilage, and skin.
The thin band of cartilage where bone growth occurs is called the epiphysis plate. The plate's chondrocytes are under constant division by mitosis.
Protein manufacture occurs on the ribosomes.
The protein collagen is very important in cartilage integrity and function
poliphods
Ribosomes are the site of protein synthesis
Gelatin is a protein extracted from bone and cartilage by boiling.
Bone spirs, arthritis, fluid build up
