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 ...
TA2. 6327. FMA. 53488. Anatomical terms of neuroanatomy. [ edit on Wikidata] The carotid branch of the glossopharyngeal nerve (carotid sinus nerve or Hering's nerve) is a small branch of the glossopharyngeal nerve (cranial nerve IX) that innervates the carotid sinus, and carotid body.
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]
Baroreflex activation therapy. Baroreflex activation therapy is an approach to treating high blood pressure and the symptoms of heart failure. It uses an implanted device to electrically stimulate baroreceptors in the carotid sinus region. This elicits a reflex response through the sympathetic and vagal nervous systems that reduces blood pressure.
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 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.
