The anterior cranial fossa is a depression in the floor of the cranial vault which houses the projecting frontal lobes of the brain. It is formed by the orbital plates of the frontal the cribriform plate of the ethmoid and the small wings and front part of the body of the sphenoid; it is limited behind by the posterior borders of the small wings of the sphenoid and by the anterior margin of the chiasmatic groove. The lesser wings of the sphenoid separate the anterior and middle fossae.
