Carotid artery may refer to: Common carotid artery, often "carotids" or "carotid", an artery on each side of the neck which divides into the external carotid artery and internal carotid artery; External carotid artery, an artery on each side of the head and neck supplying blood to the face, scalp, skull, neck and meninges
The common carotid artery is contained in a sheath known as the carotid sheath, which is derived from the deep cervical fascia and encloses also the internal jugular vein and vagus nerve, the vein lying lateral to the artery, and the nerve between the artery and vein, on a plane posterior to both. On opening the sheath, each of these three ...
The carotid body is a small cluster of peripheral chemoreceptor cells and supporting sustentacular cells situated at the bifurcation of each common carotid artery in its tunica externa. [ 1 ] [ 2 ] The carotid body detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of arterial oxygen , but also ...
In human anatomy, the internal and external carotid arise from the common carotid artery, where it bifurcates at cervical vertebrae C3 or C4. The internal carotid artery supplies the brain , including the eyes, [ 2 ] while the external carotid nourishes other portions of the head, such as the face , scalp , skull , and meninges .
Carotid artery, common – In anatomy, the left and right common carotid arteries (carotids) [102] [103]) are arteries that supply the head and neck with oxygenated blood; they divide in the neck to form the external and internal carotid arteries. [104] [105] Carotid artery, external – The external carotid artery is a major artery of

The external carotid artery arises from the common carotid artery just inferior to the upper border of the thyroid cartilage. [1] At its origin, this artery is closer to the skin and more medial than the internal carotid, and is situated within the carotid triangle.
Also present is the inferior tympanic branch, which ascends towards the middle ear cavity; it is involved in internal carotid artery reconstitution via the "aberrant carotid artery" variant. The muscular branch of the ascending pharyngeal artery is in equilibrium with the odontoid arcade from the vertebral artery.
