The external carotid artery is covered by the skin, superficial fascia, platysma muscle, deep fascia, and anterior margin of the sternocleidomastoid; it is crossed by the hypoglossal nerve, by the lingual, ranine, common facial, and superior thyroid veins; and by the digastricus and stylohyoideus muscles; higher up it passes deeply into the ...
Arteries of the neck. The right common carotid artery – labeled Common caroti in the figure – divides into the right internal carotid artery and external carotid artery. The cervical portions of the common carotids resemble each other so closely that one description will apply to both. [citation needed]

On the right side it starts from the brachiocephalic artery (a branch of the aorta), and on the left side the artery comes directly off the aortic arch. At the throat it forks into the internal carotid artery and the external carotid artery. The internal carotid artery supplies the brain, and the
The blood supply to the common carotid artery starts at the arch of the aorta (left) or the subclavian artery (right). The common carotid artery divides into the internal carotid artery and the external carotid artery. Plaque often builds up at that division, and a carotid endarterectomy cuts open the artery and removes the plaque.
The facial artery arises in the carotid triangle from the external carotid artery, [1] [2] a little above the lingual artery, and sheltered by the ramus of the mandible.It passes obliquely up beneath the digastric and stylohyoid muscles, over which it arches to enter a groove on the posterior surface of the submandibular gland.
Carotid agenesis is a vascular anomaly in which the carotid artery, normally present in the neck, does not develop during embryogenesis. [1] The common carotid artery splits into the external carotid artery and internal carotid artery, with the internal carotid artery supplying blood flow to areas of the brain.
