Internal Carotid Artery

The inherent carotid arterial blood vessel supplies the anterior part of the brain, the obtain mall and its appendages, and sends branches to the forehead and nose. Its size, in the adult, is equal to that of the foreign carotid, though, in the child, it is big than that vessel. It is remarkable for the number of curvatures that it presents in different split of its course. It from time to time has one or two flexures get along the base of the skull, man in its passage through the carotid canal and on the side of the body of the sphenoid uprise it describes a copy curvature and resembles the italic letter S. This artery may be divided into four shell outs: cervical, petrous, cavernous, and cerebral. The cervical Portion of the internal carotid begins at the bifurcation of the common carotid, reverse the upper b arrange of the thyroid cartilage, and runs perpendicularly upward, in anterior of the transverse military operationes of the upper leash cervical verteb rae, to the carotid canal in the petrous portion of the temporal bone.

It is relatively superficial at its commencement, where it is contained in the carotid triangle, and lies behind and askant to the external carotid, overlapped by the Sternocleidomastoideus, and covered by the deep fascia, Platysma, and integument, it consequently passes beneath the parotid gland, being cross by the hypoglossal heart nerve, the Digastricus and Stylohyoideus, and the occipital and posterior auricular arteries. high up, it is separated from the external carotid by the Styloglossus and Stylopharyngeus, the tip of the styloid process and the stylohyoid ligament, the glosso pharyngeal nerve and the phar yngeal branch of the vagus. It is in relatio! n, behind, with the Longus capitis, the fantabulous cervical ganglion of the likable trunk, and the superior laryngeal nerve; laterally, with the internal jugular venous blood vessel and vagus nerve, the nerve lying on a rag posterior to the artery; medially, with the pharynx, superior laryngeal nerve, and ascending pharyngeal artery.
