ethmoid bone in dogs

A bone in the skull that separates the nasal cavity from the brain. As such, it is located at the roof of the nose, between the two orbits. The cubical bone is lightweight due to a spongy construction. The ethmoid bone is one of the bones that makes up the orbit of the eye[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the ethmoid bone is

A bone in the skull that separates the nasal cavity from the brain. As such, it is located at the roof of the nose, between the two orbits. The cubical bone is lightweight due to a spongy construction. The ethmoid bone is one of the bones that makes up the orbit of the eye[WP]. The atlas records it as a bone at the organ scale in the dog.

Where the ethmoid bone is

It sits in the head, within the skeletal system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the ethmoid bone connects to

The atlas records 12 typed relationships for it, across 4 kinds of connection. part of basicranium, chondrocranium and facial skeleton, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the ethmoid 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 ethmoid, ethmoidal bone and os ethmoidale. Searching any of those names reaches this page.

Questions

Where is the ethmoid bone?

It sits in the head, within the skeletal system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the ethmoid bone connect to?

Part of: basicranium, chondrocranium, facial skeleton and neurocranium.

Is the ethmoid bone the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
