Anterior Cranial Fossa
The Anterior Cranial Fossa (pronounced: an-TEER-ee-or KRAY-nee-al FOSS-uh) is a depression in the floor of the cranium that houses the projecting frontal lobes of the brain.
Etymology
The term "Anterior Cranial Fossa" is derived from Latin and Greek roots. "Anterior" comes from the Latin word 'anterior' meaning 'before' or 'in front of'. "Cranial" is derived from the Greek word 'kranion' which means 'skull'. "Fossa" is a Latin term meaning 'ditch' or 'trench'.
Anatomy
The Anterior Cranial Fossa is the most forward of the three depressions in the base of the skull. It is formed by parts of the frontal bone, the lesser wings of the sphenoid bone, and the ethmoid bone. It accommodates the frontal lobes of the cerebrum and contains several foramina (openings) through which nerves and blood vessels pass.
