maxilla
The bone which normally forms the lateral upper jaw in osteichthyans, including tetrapods. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the maxilla is
The bone which normally forms the lateral upper jaw in osteichthyans, including tetrapods. The atlas records it as a bone at the organ scale in the human body.
Where the maxilla is
It sits in the head, within the skeletal and digestive systems. Positioned deliberately as part of this species body plan.
What the maxilla connects to
The atlas records 51 typed relationships for it, across 9 kinds of connection. part of anatomical structure, axial skeletal system and craniocervical region, and 10 more.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the maxilla. 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 upper jaw bone, maxillae and maxillary bone. Searching any of those names reaches this page.

Questions
Where is the maxilla?
It sits in the head, within the skeletal and digestive systems. Positioned deliberately as part of this species body plan.
What does the maxilla connect to?
Part of: anatomical structure, axial skeletal system, craniocervical region, digestive system, facial skeleton and head, and 7 more.
Is the maxilla 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.
