Is a symphysis a joint in which the bones are joined by a disc of fibrocartilage?
A symphysis is a joint in which the bones are joined by a disc of fibrocartilage.
It is really a fusion between two bones in which the fibrous bundles of collagen allow only limited movement.
Two examples of symphyses are:
The pubic symphysis
The pubic symphysis is the midline cartilaginous joint uniting the left and right pubic bones.
It widens slightly whenever the legs are stretched far apart and can become dislocated.
The intervertebral disks
The intervertebral discs lie between adjacent vertebrae in the spine.
Each disc forms a cartilaginous joint to allow slight movement of the vertebrae and acts as a ligament to hold the vertebrae together.
