Common carotid arteries picture
The arteries that provide the major portion of blood supply
to the head and neck are the left and right common carotid, each of which divides into two
branches: the external carotid, supplying the neck, the face, and the exterior of the
head; and the internal carotid artery, supplying the anterior brain, eye, orbit, and
sinuses. You can feel your pulse by placing your fingertips along the common carotid
artery in the neck.
