Bone, ethmoid


Bone, ethmoid
An irregularly shaped bone that provides the floor of the front part of the skull and the roof of the nose. The ethmoid bone consists of two masses of thin plates enclosing air cells and looks like a sieve. The word "ethmoid" comes from two Greek words: "ethmos" meaning sieve + "eidos" meaning resemblance = resembling a sieve.
