The foramen lacerum is variably sized gap with three borders. Its anterior border is the sphenoidal body at the junction of the greater wing and pterygoid process. The posterior border is the medial end of the petrous temporal bone. The medial border is the basioccipital bone. It is filled by connective tissue in life and transmits the small meningeal branches of the ascending pharyngeal artery and emissary veins from the cavernous sinus.
