basioccipital bone in dogs

One of the bones of the occiput, the part of the skull which articulates with the spine. The basioccipital is located (if present) ventral to the foramen magnum. It often rests on or articulates with the basisphenoid, as well as meeting the exoccipitals. The basioccipital usually forms most (sometimes all) of the occipital condyle(s) and the ventral margin of the foramen magnum. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the basioccipital bone is

One of the bones of the occiput, the part of the skull which articulates with the spine. The basioccipital is located (if present) ventral to the foramen magnum. It often rests on or articulates with the basisphenoid, as well as meeting the exoccipitals. The basioccipital usually forms most (sometimes all) of the occipital condyle(s) and the ventral margin of the foramen magnum. The atlas records it as a bone at the organ scale in the dog.

Where the basioccipital 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 basioccipital bone connects to

The atlas records 10 typed relationships for it, across 4 kinds of connection. part of anatomical structure, basicranium and chondrocranium, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the basioccipital 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 basi-occipital, basilar part of occipital bone, basioccipital, basioccipital bone and pars basilaris ossis occipitalis. Searching any of those names reaches this page.

Questions

Where is the basioccipital 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 basioccipital bone connect to?

Part of: anatomical structure, basicranium, chondrocranium and cranium.

Is the basioccipital 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.
