200
Organic components-40% dry weight of bone, collagen, proteoglycan, glycoproteins and phospholipids
What is bone matrix?
200
Absorption of water by cartilage causes cracks to develop in the the surface of the cartilage
What is fibrillation?
300
Responsible for the property of cartilage that allows it to absorb and expel water
What are proteoglycans?
300
Connective tissue rich in blood vessels, nerve endings, and lymph vessels
What is the periosteum?

300
Ossify sometime after puberty
What are ephphysial plates (growth plates)?

What is eburnation?
400
Fills the joint space, providing lubrication and nutrition for the bone ends
