Figure 3. Later this semester (Lab 10), you will learn that the axillary artery is a continuation of the subclavian artery. In the axilla, the axillary nerve is located posterior to the axillary artery and anterior to the subscapularis muscle. Blood Supply of the Brachial Plexus The blood supply of the brachial plexus is based largely on the subclavian (which becomes the axillary) artery and its branches, and variations exist. It consists of three heads: lateral, medial and long head and serves primarily to extend the forearm. In human anatomy, the axillary vein is a large blood vessel that conveys blood from the lateral aspect of the thorax, axilla (armpit) and upper limb toward the heart. Blood supply of the upper limb. The blood supply to the upper limb (shoulder, arm and hand) starts as the subclavian arteries in the shoulders. Axillary artery (and branches) – the main artery supplying the upper limb. This space transmits the subscapular artery and the axillary nerve. It is commonly referred as having three parts; one medial to the pectoralis minor, one posterior to pectoralis minor, and one lateral to pectoralis minor. The brachial artery gives off a deep brachial artery high in the arm, which courses in the posterior compartment. (1993) describe a so-called coracobrachial artery as being responsible for blood supply to the LHBT. Major arterial anastomoses of the upper extremity. Illustration of chest, section. It is a direct continuation of the posterior cord from the brachial plexus – and therefore contains fibres from the C5 and C6 nerve roots. Its origin is at the lower margin of the teres major muscle and a continuation of the brachial vein. “The second part of the axillary artery gets occluded by the overlying pectoralis minor muscle when the arm was hyperabducted and brought overhead.” This was described by Wright in 1945.
