The Median Nerve.
—The median nerve lies in front of the brachial artery and is exposed through an incision as if the artery were to be tied in its course. It may also be found on the inner side of the tendon of the palmaris longus, where it lies beneath the deep fascia.
The Ulnar Nerve.
—The ulnar nerve is reached through practically the same incision as the median, when it is sought in the middle of the arm, but is farther back. It lies near the surface, just behind the inner condyle, between it and the olecranon, and at the wrist it is on the radial side of the tendon of the flexor carpi ulnaris.
