Mandibular symphysis

Other Terms: Symphysis mandibulae, Symphyse mentonnière

Description

This is the fusion surface between the two halves of the mandible. It is not evident in the adult bone except sometimes as a faint ridge on the upper, external, midline surface of the bone.

Etymology

Mandible originally arose from the Latin verb mandere meaning to chew. Symphysis comes from the Greek word sumphusis denoting to grow together. This arises from the Greek sun meaning together and phuo meaning to grow. The term appeared in the writings of both Hippocrates and Galen. During the 16th Century English anatomists used this to describe joints that had no motion.
