Recommended video: Inferior view of the base of the skull [23:24]
Structures seen on the inferior view of the base of the skull.

The carotid canal is a passageway in the petrous part of the temporal bone of the skull. Its large, circular external (inferior) opening is known as the carotid foramen, which lies immediately anterior to the jugular foramen. From a superior view of the base of the skull, the internal (superior) opening of the carotid canal lies immediately posterolateral to the foramen lacerum. The carotid canal is approximately 2cm long and opens into the middle cranial fossa

The carotid canal transmits the internal carotid artery, as well as the internal carotid venous plexus and the internal carotid plexus.
