The common carotid arteries are present on the left and right sides of the body. These arteries originate from different arteries but follow symmetrical courses. The right common carotid originates in the neck from the brachiocephalic trunk; the left from the aortic arch in the thorax.
The common carotid artery is the large artery whose pulse can be felt on both sides of the neck under the jaw. 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.
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
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.

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 ...
Left external carotid artery with normal spectral doppler ultrasound. The condition and health of the external carotid arteries is usually evaluated using Doppler ultrasound, CT angiogram or phase contrast magnetic resonance imaging (PC-MRI). Typically, blood flow velocities in the external carotid artery are measured as peak systolic velocity ...
The brachiocephalic artery, brachiocephalic trunk, or innominate artery is an artery of the mediastinum that supplies blood to the right arm, head, and neck. [1] [2] It is the first branch of the aortic arch. [3] Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. [4]
