A synarthrosis is a type of joint which permits little or no mobility. Most synarthrosis joints are fibrous.

Suture joints and synchondroses are synarthroses.cite web |url=http://anatomy.med.umich.edu/modules/joints_module/joints_02.html |title=Module - Introduction to Joints |accessdate=2008-01-29 |format= |work=]

Types

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 separated 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.
