Like other flexion surfaces of large joints (groin, popliteal fossa, armpit and essentially the anterior part of the neck), it is an area where blood vessels and nerves pass relatively superficially, and with an increased amount of lymph nodes. In humans the fibers of the radial nerve originate in the lower cervical and upper thoracic spinal cord (usually C5 to T1), travel via the posterior cord of the brachial plexus, and supply motor innervation to extensor muscles of the arm and cutaneous sensory fibers to extensor regions of the arm and hand. Remember TAN - in the cubital fossa, the biceps Tendon lies lateral, the brachial Artery is intermediate, and the median Nerve is most medial. It is located anterior to the elbow joint. The ulnar nerve is found in the forearms medial side, the palms ulnar side, the little finger, and the ulnar half of the ring finger. The median nerve on the medial side of the brachial artery.
