In anatomy, the left and right common carotid arteries (carotids) (English: / k ə ˈ r ɒ t ɪ d / [1] [2]) are arteries that supply the head and neck with oxygenated blood; they divide in the neck to form the external and internal carotid arteries.
The internal carotid artery is an artery in the neck which supplies the anterior and middle cerebral circulation. [1]In human anatomy, the internal and external carotid arise from the common carotid artery, where it bifurcates at cervical vertebrae C3 or C4.
The external carotid artery is the major artery of the head and upper neck. It arises from the common carotid artery . It terminates by splitting into the superficial temporal and maxillary artery within the parotid gland .

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 ...
The circle of Willis is a part of the cerebral circulation and is composed of the following arteries: [3] Anterior cerebral artery (left and right) at their A1 segments; Anterior communicating artery; Internal carotid artery (left and right) at its distal tip (carotid terminus) Posterior cerebral artery (left and right) at their P1 segments
In human anatomy, the left and right posterior communicating arteries are small [1]: 471 arteries at the base of the brain that form part of the circle of Willis. Anteriorly, it unites with the internal carotid artery (ICA) (prior to the terminal bifurcation of the ICA into the anterior cerebral artery and middle cerebral artery ); posteriorly ...
