Radial collateral artery
The radial collateral artery is an artery that is part of the deep brachial artery. It is the anterior terminal branch that reconnects with the radial recurrent artery via anastomosis. Upon anastomosing, the artery makes up a section of the elbow's articular vascular plexus. The lateral branch emerges straight out of the arm. The artery is situated within the profunda brachii, also known as the deep brachial artery. The profunda brachii is a term for a vast vessel that comes out from both the posterior and lateral segments of the brachial artery, right below the lower edge of the upper limb's teres major muscle. The profunda brachii runs alongside the radial nerve and then after runs within its groove, which is called the radial sulcus. It also provides the deltoid muscles with several branches. The radial collateral artery is also closely associated with the inferior ulnar collateral artery, the medial ulnar collateral artery, and the superior ulnar collateral artery.
