The ethmoid bone (/ˈɛθmɔɪd/; from Greek ethmos, "sieve") is a 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 bone is lightweight due to a spongy construction. The ethmoid bone is one of the bones that makes up the orbit of the eye. The ethmoid has three parts: the cribriform plate, the ethmoidal labyrinth, and the perpendicular plate.

Famous quotes containing the word bone:
“Here lies the body of William Jones
Who all his life collected bones,
Till Death, that grim and boney spectre,
That universal bone collector,
Boned old Jones, so neat and tidy,
And here he lies, all bona fide.”
—Anonymous. “Epitaph on William Jones,” from Eleanor Broughton’s Varia (1925)
