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

Suture joints and Gomphosis joints are synarthroses.[1]

Types

They can be categorised by how the two bones are joined together:

  • Gomphoses are found in the sockets of the teeth. The socket of a tooth is often referred to as a gomphosis (type of a joint in which a conical peg fits into a socket). Normally, there should be an absolutely minimal amount of movement of the teeth in the mandible or maxilla.
  • 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 cranial plates 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.
  • Synchondroses are cartilaginous joint connected by hyaline cartilage, as seen in the epiphyseal plate.
  • Sutures are fibrous joints made of a thin layer of dense fibrous connective tissue that unites skull bones.[2]
