The external carotid artery is covered by the skin, superficial fascia, platysma muscle, deep fascia, and anterior margin of the sternocleidomastoid; it is crossed by the hypoglossal nerve, by the lingual, ranine, common facial, and superior thyroid veins; and by the digastricus and stylohyoideus muscles; higher up it passes deeply into the ...
The occipital artery is a branch of the external carotid artery that provides arterial supply to the back of the scalp, sternocleidomastoid muscles, and deep muscles of the back and neck. Structure [ edit ]
The blood supply of the scalp is via five pairs of arteries, three from the external carotid and two from the internal carotid: internal carotid the supratrochlear artery to the midline forehead. The supratrochlear artery is a branch of the ophthalmic branch of the internal carotid artery.
Carotid artery, common – In anatomy, the left and right common carotid arteries (carotids) [102] [103]) are arteries that supply the head and neck with oxygenated blood; they divide in the neck to form the external and internal carotid arteries. [104] [105] Carotid artery, external – The external carotid artery is a major artery of
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, including the eyes, [2] while the external carotid nourishes other portions of the head, such as the face, scalp, skull, and meninges.
The facial artery arises in the carotid triangle from the external carotid artery, [1] [2] a little above the lingual artery, and sheltered by the ramus of the mandible.It passes obliquely up beneath the digastric and stylohyoid muscles, over which it arches to enter a groove on the posterior surface of the submandibular gland.
Carotid artery may refer to: Common carotid artery , often "carotids" or "carotid", an artery on each side of the neck which divides into the external carotid artery and internal carotid artery External carotid artery , an artery on each side of the head and neck supplying blood to the face, scalp, skull, neck and meninges
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 ...
