sphenoid bone in dogs
An unpaired bone situated at the base of the skull in front of the temporal bone and basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the sphenoid bone is
An unpaired bone situated at the base of the skull in front of the temporal bone and basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended. The atlas records it as a bone at the organ scale in the dog.
Where the sphenoid 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 sphenoid bone connects to
The atlas records 21 typed relationships for it, across 8 kinds of connection. part of facial skeleton.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the sphenoid 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 os sphenoidale, sphenoid, sphenoidal bone, butterfly bone, os sphenoidum and sphenoid complex. Searching any of those names reaches this page.
