 Arteries - LoveToKnow 1911
The vertebral and internal carotid arteries, which are the arteries of supply for the brain, are distinguished by lying at some depth from the surface in their course to the organ, by having curves or twists in their course, and by the absence of large collateral branches.
The single arteries are the coeliac axis, the superior mesenteric, and the inferior mesenteric, which arise from the front of the aorta; the pairs are the capsular, the two renal, and the two spermatic or ovarian, which arise from its sides.
The arteries which supply the coats of the alimentary tube from the oesophagus to the rectum anastomose freely with each other in the wall of the tube, or in its mesenteric attachment, and the anastomoses are usually by the formation of arches or loops between adjacent branches.

The artery may arise as a separate trunk from the arch of the aorta, and in such cases it may be either the first, second, third, or even the last branch derived from that vessel; in the majority, however, it is the first or last, rarely the second or third.
It anastomoses with the ascending pharyngeal and occipital arteries.
The ascending branch (ramus ascendens; superficial cervical artery) ascends beneath the anterior margin of the Trapezius, distributing branches to it, and to the neighboring muscles and lymph glands in the neck, and anastomosing with the superficial branch of the descending ramus of the occipital artery.

 Subclavian artery - Wikipedia, the free encyclopedia
The left subclavian artery is the fifth branch of the aorta and the third branch from the arch of the aorta.
The usual branches of the subclavian on both sides of the body are the internal thoracic artery, the vertebral artery, the thyrocervical trunk, and the costocervical trunk.
From its origin, the subclavian artery travels laterally, passing between anterior and middle scalene muscles, with the anterior scalene (scalenus anterior) on its anterior side and the middle scalene (scalenus medius) on its posterior.

 eMedicine - Subclavian Steal Syndrome : Article by Kenneth E McIntyre, MD
The internal mammary artery arises from the inferior aspect of the proximal subclavian artery, opposing the origin of the vertebral artery.
However, if the cause of subclavian steal syndrome is atherosclerotic stenosis or occlusion of the proximal subclavian artery, treat patients with lifelong antiplatelet therapy to reduce the risk of associated myocardial infarction, stroke, and other vascular causes of death.
Subclavian transposition requires more proximal dissection of the subclavian artery to ensure that enough length of artery is available to perform the anastomosis without undue tension.

 Central Vasculature
The main artery of the heart is the aorta, which originates from the left ventricle of the heart and then gives rise to branches that course upward and downward to supply all body tissues with oxygen and nutrients.
Arteries are thus well adapted to their function of carrying blood under pressure and veins to their function of serving as a reservoir to maintain a steady return of blood to the heart.
The second and third branches of the aortic arch are the left common carotid artery which transports blood to the left side of the head and the neck, and the left subclavian artery, which transports blood to the left upper limb.

 The Arteries
The right subclavian artery is a continuation of the brachiocephallic trunk, while the left subclavian arises directly from the aortic arch.
The axillary artery begins at the outer border of the first rib and ends at the lower border of the teres major muscle where it becomes the brachial artery.
The subscapular artery lies on the anterior surface of subscapularis and is accompanied on its course to the latissimus dorsi muscle by the thoracodorsal nerve.

The left subclavian passes behind the esophagus and then gives rise to the ligamentum arteriosum, which passes anteriorly to connect to the left pulmonary artery, thereby completing the vascular ring.
There is a right aortic arch that gives off, in sequence, the left innominate artery (left common carotid with left subclavian), the right common carotid, and the right subclavian artery.

 Vertebral artery - Wikipedia, the free encyclopedia
The vertebral arteries are branches of the subclavian arteries.
The basilar artery is the main blood supply to the brainstem and connects to the Circle of Willis to potentially supply the rest of the brain if there is compromise to one of the carotids.
This part of the artery is covered by the Semispinalis capitis and is contained in the suboccipital triangle—a triangular space bounded by the Rectus capitis posterior major, the Obliquus superior, and the Obliquus inferior.
