Arterial Supply Anatomy The brachial artery commences at the lower margin of the tendon of the Teres major, and, passing down the arm, ends about 1 cm. below the bend of the elbow, where it divides into the radial and ulnar arteries.

Branches of the Aorta Trace the aorta from the point at which it leaves the left ventricle. The first branch of the aorta is the brachiocephalic trunk. It branches into the right subclavian artery and the right and left common carotid arteries.he common carotid arteries supply the head region with oxygenated blood. The left subclavian artery is the next branch (the second) from the aorta. Its branches are similar to the right subclavian.

Arteries of the Upper Limb Arteries of the Upper Limb. The arterial supply to the upper limb begins in the chest as the subclavian artery. The right subclavian artery arises from the brachiocephalic trunk, while the left subclavian branches directly off the arch of aorta. When the subclavian arteries cross the lateral edge of the 1st rib, they enter the axilla, and are called axillary arteries.

Axillary artery In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb.Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.he axillary artery is often referred to as having three parts, with these divisions based on its location relative to the Pectoralis minor muscle, which is superficial to the artery. 1  First part-the part of the artery medial to pectoralis minor.

Vascular and Cerebrospinal Supply of the Spinal Cord The vertebral artery is a major artery of the neck that passes through the cervical vertebrae. There are two vertebral arteries, one on each side, and each branches off from the subclavian artery. They merge to form the single basilar artery at the base of the brain.

It then divides into the radial and ulnar arteries which run down the forearm.t is the continuation of the axillary artery beyond the lower margin of teres major muscle.

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).

Chapter 8: The shoulder and axilla Brachial plexus (figs. 8-1, 8-7, 8-8 and 8-9) The nerves to the upper limb arise from the brachial plexus, which is situated partly in the neck and partly in the axilla. It is formed by the union of the ventral rami of the lower four cervical and first thoracic nerves (C5,6,7,8; T1). Frequently it receives a contribution from one nerve higher or one nerve lower.

Axillary Artery The other branch of the second part of the axillary artery is the lateral thoracic artery. It travels inferomedially along the inferior margin of pectoralis minor. It carries oxygenated blood for the serratus anterior, the pectorales muscles, the subscapularis muscle as well as for the mammaries.

Upper Body Arteries & Veins Three major arteries branch off the aortic arch: brachiocephalic artery, left common carotid artery and left subclavian artery. The first branch off the aortic arch that provides blood to the head, neck and right upper limb. The left is the second brand of the aortic arch. The right arises from the brachiocephalic artery. Arises from the left common carotid arteries and supply blood to most tissues of the head, except for the brain and orbit.

Veins of the Upper Limb Like in the forearm, the arm is drained by the brachial veins (deep veins that accompany the brachial artery) and all its branches. In addition, the basilic and cephalic veins course upwards through the subcutaneous tissue and drain the superficial regions of the arm.

Circulatory Pathways In the region of the elbow, the brachial a. divides into the arteries that supply the forearm, the radial a. that follows the radius, and the ulnar a. that follows the ulna. Both the radial and ulnar aa. extend to the wrist.

Brachial artery The brachial artery is the major blood vessel of the arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle. It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow. It then divides into the radial and ulnar arteries which run down the forearm. In some individuals, the bifurcation occurs much earlier and the ulnar and radial arteries extend through the upper arm. The pulse of the brachial artery is palpable on the anterior aspect of the elbow, medial to the tendon of the biceps, and, with the use of a stethoscope and sphygmomanometer (blood pressure cuff) often used to measure the blood pressure.

6b. The Anterior Divisions 19. The ulnar artery is the branch of the brachial artery that passes down the little finger (medial) side of the forearm to the wrist. Both the radial and ulnar arteries supply blood to the forearm, and they unite to form the deep and superficial palmar arches in the hand. 20. The palmar arches are arterial loops, formed by the union of the radial and ulnar arteries. They are located at different levels within the hand (palm); the digital (finger) arteries arise from these arches.

Subclavian Artery in Gross Anatomy. The right and left subclavian arteries have separate origins. The right subclavian artery is one of the two terminal branches of the brachiocephalic artery, the other being the right common carotid artery. It arises at the level of the right sternoclavicular joint.It moves as a gentle curve behind the scalenus anterior muscle passing upwards and laterally.he right subclavian artery is one of the two terminal branches of the brachiocephalic artery, the other being the right common carotid artery. It arises at the level of the right sternoclavicular joint.

- The right axillary artery supplies vital oxygenated blood and nutrients to the armpit and upper arm area and the right side of the thorax. Blood flows from the left ventricle of the heart into the aorta then into the brachiocephalic artery and right subclavian artery, which turns into the right axillary artery.

vertebral artery The first branch of the subclavian artery; it runs up the back of the neck via foramina in the transverse processes of the cervical vertebrae and enters the cranial cavity through the foramen magnum. The right and left vertebral arteries merge along the ventral surface of the hindbrain to become the basilar artery. Branches of the vertebral artery include the anterior and posterior spinal arteries and the posterior inferior cerebellar artery. The vertebral arteries carry about 20% of the brain's blood supply, feeding the brainstem, cerebellum, and most of the posterior cerebral hemispheres.

Brachial artery The brachial artery's pulse can be felt on the elbow's front side. This is why blood pressure is measured in this area using either a sphygmomanometer (a blood pressure meter) or a stethoscope.

- Locate the brachial artery in the cubital fossa (between the biceps brachii tendon and the median nerve) and follow it down into the forearm. 1  Follow the ulnar artery distal to the point at which it crosses under the median nerve. 2  Locate here the common interosseous branch of the brachial artery.

Brachial veins The brachial veins are located in the arm proper, the area between the shoulder and the elbow, and run alongside the brachial artery. The brachial veins work in reverse from the brachial artery. The ulnar and radial veins form a junction at the location where the brachial veins begin. The teres major muscle has an inferior border where the brachial veins end. At this point, they join to form the axillary vein.

Blood Vessels Of The Upper Limb Arteries of the upper limb. Aorta. arch of aorta gives off three branches. a) brachiocephalic artery-divides into: 1) right common carotid artery-passes superiorly into neck. 2) right subclavian artery-arches laterally, deep to clavicle; to right upper limb. b) left common carotid artery-directly off arch of aorta. c) left subclavian artery-directly off arch f aorta; to left upper limb.
