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; it transmits into the cranium the internal carotid artery, and the carotid plexus of nerves.

This portion of the internal carotid begins at the bifurcation of the common carotid, opposite the upper border of the thyroid cartilage, and runs perpendicularly upward, in front of the transverse processes of the upper three cervical vertebræ, to the carotidcanal in the petrous portion of the temporal bone.
It is in relation, behind, with the Longus capitis, the superior cervical ganglion of the sympathetic trunk, and the superior laryngeal nerve; laterally, with the internal jugular vein and vagus nerve, the nerve lying on a plane posterior to the artery; medially, with the pharynx, superior laryngeal nerve, and ascending pharyngeal artery.
The artery is separated from the bony wall of the carotidcanal by a prolongation of dura mater, and is surrounded by a number of small veins and by filaments of the carotid plexus, derived from the ascending branch of the superior cervical ganglion of the sympathetic trunk.
In all known members the canalis caroticus internus (internal carotidcanal) is partially formed by the pterygoid.
In generalized amniotes, the foramen by which the internal carotid artery enters the skull is formed entirely within the basisphenoid.
In pleurosternids and baenids, both the pterygoid and the basisphenoid form the actual entry foramen of the carotid (supporting monophyly of the Paracryptodira), while in other cryptodires the canals are buried within the pterygoid (Gaffney, 1979; Gaffney and Meylan, 1988).
