Ethmoid bone (superior and lateral views) (Latin)

The superior view allows the appreciation of one of the most unique landmarks of the ethmoid bone: the lamina cribrosa. The lamina cribrosa is split into left and right halves by the crista galli. The plate presents multiple openings through which the fibers of the n. olfactorius pass. The fibers converge into the bulbi olfactorii, each resting on the respective surfaces of the lamina cribrosa.The lateral view provides a better visualization of the lamina perpendicularis. It forms a part of the septum nasi and articulates with the vomer.
