Inferior ulnar collateral artery the anterior ulnar recurrent. Behind the medial epicondyle a branch anastomoses with the superior ulnar collateral and posterior ulnar recurrent arteries. Inferior ulnar collateral artery The inferior ulnar collateral artery (anastomotica magna artery) is a artery in the arm. It arises about 5 cm. above the elbow from the brachial artery. It passes medialward upon the Brachialis, and piercing the medial intermuscular septum, winds around the back of the humerus between the Triceps brachii and the bone, forming, by its junction with the profunda brachii, an arch above the olecranon fossa. As the vessel lies on the brachialis, it gives
Suprascapular artery Suprascapular artery The suprascapular artery is a branch of the thyrocervical trunk. At first, it passes downward and laterally across the scalenus anterior and phrenic nerve, being covered by the sternocleidomastoid muscle; it then crosses the subclavian artery and the brachial plexus, running behind and parallel with the clavicle and subclavius muscle and beneath the inferior belly of the omohyoid to the superior border of the scapula. It passes over the superior transverse scapular ligament (unlike the suprascapular nerve, which passes below the ligament). The artery then enters the supraspinatous fossa of the scapula. It travels close to the bone,
