It transmits into the cranium the internal carotid artery, and the carotid plexus of nerves.
Sympathetics to the head also pass through the carotid canal. They have several motor functions: raise the eyelid (superior tarsal muscle), dilate pupil, innervate sweat glands of face and scalp and constricts blood vessels in head.
