==Joint Formation==

*Joints begin to form as the mesenchyme is condensing.

Joints begin to form as the mesenchyme is condensing. Joint - forming cells develop different characteristics to cartilage precursors; they are flat and densely packed. The region where these joint - forming cells exist is called the "interzone". There are three layers in the interzone; a middle layer of low density with regions of high density either side. The high density regions form [[Bones and Cartilage - Anatomy & Physiology#Cartilage Structure and Function|cartilage]]. The middle layer is eliminated by cell death, forming the joint space.
