==Joint Formation==
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 cartilage. The middle layer is eliminated by cell death, forming the joint space.
