Description:
Ethnoid bone: superior view. The ethmoid bone is localized between the orbits and is a significant part of the nasal cavity. It is an unpaired bone, made almost entirely by thin bony lamellae. Note that multiple ethmoid cells open on top of the etmoidal labyrinth. The most ventral ethmoid cells communicate with the frontal sinus, and the dorsal ones are covered by the pars orbitalis ossis frontalis. The foramen ethmoidale anterius localized on the medial wall of the orbit connects the orbit with the fossa cranii anterior via a channel bordered by the ethmoid bone (channel's floor) and the frontal bone (the channel's roof). This channel is known as canalis ethmoidalis anterior, is about 6 mm long, and contains clinically important a. ethmoidalis anterior. Latin labels.
