mandible

A dentary bone that is the only bone in one of the lateral halves of the lower jaw skeleton. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the mandible is

A dentary bone that is the only bone in one of the lateral halves of the lower jaw skeleton. The atlas records it as a bone at the organ scale in the human body.

Where the mandible is

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

What the mandible connects to

The atlas records 55 typed relationships for it, across 8 kinds of connection. part of axial skeletal system, craniocervical region and digestive system, and 10 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the mandible. 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.

Also called

Also recorded as lower jaw, lower jaw bone, inferior maxillary bone, mammaliam mandible, mandibulla and lower mandibula, and 2 more. Searching any of those names reaches this page.

Questions

Where is the mandible?

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

What does the mandible connect to?

Part of: axial skeletal system, craniocervical region, digestive system, facial skeleton, head and jaw skeleton, and 7 more.

Is the mandible 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.
