-Brachial fascia surrounding anterior arm muscles and posterior arm muscles

Name the muscles of the posterior arm and the anterior arm.

Posterior- triceps brachii long head, lateral head, medial head and brachioradialis


Anterior- biceps brachii long head, short head, Coracobrachialis and brachialis
