==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.
