Cardiovascular System of the Head and Neck From there the basilar artery provides blood to the posterior structures of the brain, including the brain stem, cerebellum, and cerebrum. The left and right carotid arteries each divide in the neck to form the left and right internal carotid as well as the left and right external carotid arteries.

Internal Carotid Artery Internal Carotid Artery. The internal carotid artery is one of the two arterial branches that stems from the common carotid artery. The carotid artery arises both directly and indirectly from the arch of the aorta, depending on which side of the body it belongs to.tenosis of the carotid arteries, which include both the common carotid as well as the internal and external branches, is most commonly caused by a pathological disorder known as arteriosclerosis.

artery Maxillary Artery Branches. The Buccal artery is a small artery of the head and a branch of the second part of the maxillary artery (the 7th branch of the external carotid) and supplies both the buccinator muscle and cheek. The maxillary artery (the 7th branch of the external carotid) gives off an infraorbital artery.

External carotid artery The external carotid arteries supply oxygenated blood to the head region. There is one external carotid artery on the right side of the neck and one on the left side of the neck. Each begins at the common carotid artery and moves up the neck until it divides into the superficial temporal artery and the maxillary artery.

Brachiocephalic Trunk The brachiocephalic trunk is another word for the brachiocephalic artery. The brachiocephalic artery supplies blood to the tissues of the brain and the head. It is the first branch of the aortic arch and rises up to a point near the junction of the sternum (breast bone) and the right clavicle (collarbone).

3. The Arteries of the Head and Neck. a. The Common Carotid Artery Behind the angle of bifurcation of the common carotid artery is a reddish-brown oval body, known as the glomus caroticum (carotid body). It is similar in structure to the glomus coccygeum (coccygeal body) which is situated on the middle sacral artery.

Arterial Supply Anatomy Internal carotid artery. The internal carotid artery supplies the anterior part of the brain, as well as the eye and its appendages, and sends branches to the forehead and nose. In view of its course and relations, this vessel may be divided into 4 portions: cervical, petrous, cavernous, and cerebral.

Cardiovascular System of the Head and Neck In the neck and head exterior to the skull, the external carotid artery provides blood flow to the skin, muscles, and organs. Several major arteries-including the facial, superficial temporal, and occipital arteries-branch off from the external carotid to provide blood to the many superficial structures of the head. Three pairs of major veins return deoxygenated blood from the tissues of the head and neck to the heart.
