Crista etmoidal - Crista galli
Projecting upward from the middle line of the cribriform plate is a thick, smooth, triangular process, the crista galli, so called from its resemblance to a cock’s comb. The long thin posterior border of the crista galli serves for the attachment of the falx cerebri. Its anterior border, short and thick, articulates with the frontal bone, and presents two small projecting alæ,which are received into corresponding depressions in the frontal bone and complete the foramen cecum. Its sides are smooth, and sometimes bulging from the presence of a small air sinus in the interior.
