mandibular symphysis

A cartilaginous joint that connects left and right mandibles/dentary bones. Mandibular symphysis is unpaired[TAO,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the mandibular symphysis is

Where the mandibular symphysis is

What the mandibular symphysis connects to

The atlas records 4 typed relationships for it, across 3 kinds of connection. part of lower jaw region.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the mandibular symphysis. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Questions

Where is the mandibular symphysis?

It sits within the skeletal and digestive systems. Positioned deliberately as part of this species body plan.

What does the mandibular symphysis connect to?

Part of: lower jaw region.

Is the mandibular symphysis the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
