Synchondrosis

Overview
Where the connecting medium is cartilage, a joint is termed a synchondrosis.

This is a temporary form of joint, for the cartilage is converted into bone before adult life.

Such joints are found between the epiphyses and bodies of long bones, between the occipital and the sphenoid at, and for some years after, birth, and between the petrous portion of the temporal and the jugular process of the occipital.
