“…29 An aberrant accessory phrenic nerve of good size was described, in a cadaveric study, to originate from the supraclavicular nerves forming a neural loop that anastomosed with the phrenic nerve. 30 In the upper extremity, median and ulnar nerve anastomoses are commonly found in the brachial plexus, forearm, and hand. Based on their location, type of fibers (sensory, motor, or mixed), and direction (median to ulnar or ulnar to median), four main patterns of anastomoses have been reported as two anastomoses in the forearm and two in the hand.…”
