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 internal carotid artery supplies the brain, and the external carotid artery supplies the face. This fork is a common site for atherosclerosis , an inflammatory build-up of atheromatous plaque inside the common carotid artery, or the internal carotid arteries that causes them to narrow.
Carotid artery dissection is a serious condition in which a tear forms in one of the two main carotid arteries in the neck, allowing blood to enter the artery wall and separate its layers (*dissection*). This separation can lead to the formation of a blood clot, narrowing of the artery, and restricted blood flow to the brain, potentially ...

Carotidynia is a syndrome characterized by unilateral (one-sided) tenderness of the carotid artery, near the bifurcation. It was first described in 1927 by Temple Fay. [1] The most common cause of carotidynia may be migraine, and then it is usually self-correcting. Common migraine treatments may help alleviate the carotidynia symptoms.
Cervical artery dissection has been noted to be a common cause of young adult strokes, with some sources indicating a prevalence of up to 20% in this young adult population with annual incidence rates between 2.6 and 2.9 per 100,000, although these incidences may be misleading with true incidences being higher because clinical presentations can vary, many being minor or self-limited, and thus ...
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 internal carotid plexus is a nerve plexus situated upon the lateral side of the internal carotid artery. It is composed of post-ganglionic sympathetic fibres which have synapsed at (i.e. have their nerve cell bodies at) the superior cervical ganglion. The plexus gives rise to the deep petrosal nerve.
