Synarthrosis
Gray's	subject #70 284

A synarthrosis is a type of joint which permits very little or no movement under normal conditions. Most synarthrosis joints are fibrous.

Suture joints and synchondroses are synarthroses.^[1]

[edit] 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.
