Anatomical terminology

A symphysis is a fibrocartilaginous fusion between two bones. It is a type of cartilaginous joint, specifically a secondary cartilaginous joint.

1. A symphysis is an amphiarthrosis, a slightly movable joint.
2. A growing together of parts or structures

Unlike synchondroses, symphyses are permanent.

Examples

The more prominent symphyses are:

• the pubic symphysis
• the symphyses between the bones of the skull, a common misperception about the mandible is that the (symphysis menti) (chin) is a symphyseal joint. This is a misnomer as the two halves of the mandible formed from the mandibular arch mesoderm are fused early in life and ossify to form one single bone
• sacrococcygeal symphysis
• intervertebral disc between two vertebrae
• in the sternum, between the manubrium and body, and between the body and xiphoid process
