The posterior branch of the axillary nerve pierces the deep fascia and is continued as the superior lateral cutaneous nerve of arm (or superior lateral brachial cutaneous nerve), which sweeps around the posterior border of the Deltoideus and supplies the skin over the lower two-thirds of the posterior part of this muscle, as well as that covering the long head of the Triceps brachii.
