Blood vessels of the neck,artwork. Arteries are red,veins blue and nerves yellow. The larynx is white. At bottom is the aortic arch,part of the aorta,the body's main artery. At centre the 2 common carotid arteries branch from the aortic arch and go either side of the thyroid gland. Above the thyroid gland is the carotid sinus,a dilated area in the carotid artery. It contains receptors that control blood pressure by mediating changes in heart rate. The carotid artery then splits into the external (left) and internal (right) carotid arteries. At right is the internal jugular vein which returns blood from the skull to the subclavian vein at bottom | |
