ethmoid bone

^ http://purl.obolibrary.org/obo/UBERON_0001679

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]. [ http://en.wikipedia.org/wiki/Ethmoid_bone ]

Note the WP states the Neurocranium contains the ethmoid bone, both MA and FMA place the ethmoid as part of the viscerocranium. FMA also has it in neurocranium (via basicranium). Ideally we would have non-overlapping divisions of the skull, but for now we follow FMA
