Anterior cranial fossa

Other Terms: Fossa cranii anterior, Fosse crânienne antérieure


The anterior cranial fossa houses the projecting frontal lobes of the brain. This is the most superior region of the cranial floor. The floor of the anterior fossa is formed by the orbital plates of the frontal bone, the cribriform plate of the ethmoid bone, and the small wings and front part of the body of the sphenoid bone. It is limited behind by the posterior borders of the small wings of the sphenoid and by the anterior margin of the chiasmatic groove.
