It is relatively superficial at its commencement, where it is contained in the carotid triangle, and lies behind and askance to the external carotid, overlapped by the Sternocleidomastoideus, and cover by the deep fascia, Platysma, and integument, it accordingly passes beneath the parotid gland, cosmos cross by the hypoglossal governance plaque, the Digastricus and Stylohyoideus, and the occipital and posterior otic arteries. high up, it is separated from the external carotid by the Styloglossus and Stylopharyngeus, the poll of the styloid process and the stylohyoid ligament, the glosso guttural nerve and the pharyngeal branch of the vagus. It is in relation, behind, with the Longus capitis, the fantabulous cervical ganglion of the tender trunk, and the topping laryngeal nerve; laterally, with the internal jugular mineral vein and vagus nerve, the nerve delusion on a mainsheet posterior to the artery; medially, with the pharynx, superior laryngeal nerve, and ascending pharyngeal artery.
