mandibular symphysis in dogs

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

A cartilaginous joint that connects left and right mandibles/dentary bones. Mandibular symphysis is unpaired[TAO,modified]. The atlas records it as a joint at the organ scale in the dog.

Where the mandibular symphysis is

It sits within the skeletal and digestive systems. Only the system is known. The position shown carries almost no spatial information.

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.
