From Wikipedia, the free encyclopedia
A synarthrosis is a type of joint which permits little or no mobility. Most synarthrosis joints are fibrous.
Suture joints and synchondroses are synarthroses.[1]
They can be categorised by how the two bones are joined together:
- Synchondroses are joints where the two bones are connected by a piece of cartilage.
- Synostoses are where two bones that are initially separted eventually fuse together, essentially becoming one bone. In humans the plates of the cranium fuse together as a child approaches adulthood. Children whose craniums fuse too early may suffer deformities and brain damage as the skull does not expand properly to accommodate the growing brain, a condition known as craniostenosis.
