Composition and Anatomy

Cartilage is a smooth tissue without vessel and nerves which covers joints and bone. The embryonic skeleton still exists completely of cartilage which is later transformed by calcification to bone. According to requirements cartilage is composed in different ways. Cartilage receives their nutrients from the surrounding tissue, the Perichondrium.

What does cartilage exist of?

The cells of cartilage (chondrocytes) form collagen fibers which are linked up with each other. Between the fibers a lot of water can be bound to allow elasticity and to protect against pressure load. Chemically cartilage consists of proteins and mucopolysaccharides. The growth occurs from the outside through the perichondrium.
