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 of ...
The carotid sinus is at the origin of the internal carotid artery. In human anatomy, the carotid sinus is a dilated area at the base of the internal carotid artery just superior to the bifurcation of the internal carotid and external carotid at the level of the superior border of thyroid cartilage. The carotid sinus extends from the bifurcation ...
The common carotid artery arises directly from the aorta on the left and as a branch of the brachiocephalic trunk on the right. In anatomy, the left and right common carotid arteries (carotids) (English: / kəˈrɒtɪd / [1][2]) are arteries that supply the head and neck with oxygenated blood; they divide in the neck to form the external and ...
The external carotid artery arises from the common carotid artery and supplies structures in the face and neck. 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.
3947. Anatomical terminology. [edit on Wikidata] 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 artery supplies the brain. Plaque often builds up at that division and causes a narrowing (stenosis). Pieces of plaque can break off and block the small arteries above in the brain, which causes a stroke. Plaque can also build up at the origin of the carotid artery at the aorta. [citation needed]
The carotid canal is a passage in the petrous part of the temporal bone of the skull through which the internal carotid artery and its internal carotid (nervous) plexus pass from the neck into (the middle cranial fossa of) the cranial cavity. Observing the trajectory of the canal from exterior to interior, the canal is initially directed ...
Carotid ultrasonography is an ultrasound -based diagnostic imaging technique to evaluate structural details of the carotid arteries. Carotid ultrasound is used to diagnose carotid artery stenosis (CAS) and can assess atherosclerotic plaque morphology and characteristics. [1] Carotid duplex and contrast-enhanced ultrasound are two of the most ...
