On the interior surface of the [[temporal bone]], behind the rough surface of the apex, is the large circular aperture of the '''carotid canal''', which ascends at first vertically, and then, making a bend, runs horizontally forward and medialward.
==Contents==
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.
