Internal Carotid Artery

The inherent carotid arteria 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 outside 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 rise the base of the skull, man in its passage through the carotid canal and on the side of the body of the sphenoid prepare 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, diametric the upper b night club of the thyroid cartilage, and runs perpendicularly upward, in face of the transverse military operationes of the upper leash cervical vertebrae, to the caro tid 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 thusly passes beneath the parotid gland, being cross by the twelfth cranial nerve 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 styl ohyoid ligament, the glosso pharyngeal conso! nant nerve and the pharyngeal branch of the vagus. It is in relation, behind, with the Longus capitis, the fantabulous cervical ganglion of the pitying trunk, and the superior laryngeal nerve; laterally, with the internal jugular vena and vagus nerve, the nerve lying on a sheet posterior to the artery; medially, with the pharynx, superior laryngeal nerve, and ascending pharyngeal artery.
