lacrimal bone

The irregularly thin plate that forms part of the medial wall of the orbit behind the frontal process of the maxilla. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the lacrimal bone is

The irregularly thin plate that forms part of the medial wall of the orbit behind the frontal process of the maxilla. The atlas records it as a bone at the organ scale in the human body.

Where the lacrimal bone is

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

What the lacrimal bone connects to

The atlas records 19 typed relationships for it, across 7 kinds of connection. part of axial skeletal system, craniocervical region and facial skeleton, and 5 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the lacrimal bone. 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 lacrimal, lachrymal bone, lacrymal bone, ectethmoid, infraorbital 1 and lachrymal bone - infraorbital 1, and 3 more. Searching any of those names reaches this page.

Questions

Where is the lacrimal bone?

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

What does the lacrimal bone connect to?

Part of: axial skeletal system, craniocervical region, facial skeleton, head, material anatomical entity and orbit of skull, and 2 more.

Is the lacrimal bone 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.
