Article
The ethmoid bone (/ˈɛθmɔɪd/; from Ancient Greek: ἡθμός, romanized: hēthmós, lit. 'sieve') is an unpaired bone in the skull that separates the nasal cavity from the brain. It is located at the roof of the nose, between the two orbits. The cubical (cube-shaped) bone is lightweight due to a spongy construction. The ethmoid bone is one of the bones that make up the orbit of the eye.
