common carotid arteries
are the main source of blood supply to the head, face, and neck. They are located on either side of the neck, and each one is divided into an internal external branch.
internal carotid artery
supplies blood to the brain, eyes, eyelids, forehead, nose, and internal ear.
external carotid artery
supplies blood to the anterior (front) parts of the scalp, ear, face, neck, and side of the head. The external carotid artery subdivides into several branches.
facial artery or external maxillary artery
supplies blood to the lower region of the face, mouth, and nose.
superficial temporal artery
is a continuation of the external carotid artery and supplies blood to the muscles of the front, side and top of the head.
supplies blood to the skin and muscles of the scalp and back of the head up to the crown.
posterior auricular artery
supplies the scalp, the area behind and above the ear, and the skin behind the ear.
internal and external jugular (veins)
These are the most important veins of the face and neck and are parallel to the carotid arteries. These veins transport the blood returning to the heart from the head, face, and neck.
The ulnar artery and its many branches supply the little-finger side of the arm and palm of the hand.
