Aortic arch, is part of aorta between the ascending and descending aorta. The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.
Innominate artery, sometimes referred as brachiocephalic trunk begins at aortic arch (second branch) and ends at the carotid bifurcation. Innominate artery travels upward and give rise to the right subclavian artery and the right common carotid artery. It supplies blood to the right arm, head, and neck.
Right Subclavian artery and Left subclavian artery,
On the left side of the body the subclavian comes directly from the aortic arch and ends at the thoracic outlet. whereas on the right side it arises from the brachiocephalic trunk. It enters the axilla between …show more content…
It which provides the main blood supply to the head and neck region.
Internal carotid artery, internal carotid arteries begins at the common carotid bifurcation, pass into the skull inferior to the brain through the left and right carotid foramina and ends at the circle of Willis. ICA supplies most of the anterior circulation of the cerebrum.
External carotid artery, begins at the common carotid artery and moves up the neck and it divides into the superficial temporal artery and the maxillary artery. The ECA branches supply the face, neck, and skull. The occipital artery, posterior auricular artery, facial artery, superior thyroid artery, and maxillary artery all branch off from the external carotid artery.
Vertebral, basilar, circle of Willis
Vertebral artery the vertebral arteries originate from the subclavian arteries. Each vessel courses superiorly along each side of the neck, merging within the skull it forms the single basilar artery. The vertebral arteries provide supply blood to the upper spinal cord, brainstem, cerebellum, and posterior part of …show more content…
The basilar artery carries oxygenated blood to the cerebellum, brainstem, and occipital lobes. There are many arteries branch from the basilar artery at the upper portion of the brainstem, delivering blood to various regions of the brain.
Circle of Willis is located at the base of the brain and the big clinical significance of circle of Willis is to provides potential for collateral flow between the right and left cerebral hemispheres and anterior (internal carotid) and posterior circulation (vertebrobasilar) to the brain. The anterior portion of the circle of Willis includes the internal carotid arteries, middle cerebral arteries, and anterior communicating artery. The posterior portion of the circle of Willis includes the vertebral arteries, basilar arteries, and the posterior communicating
