Brachial fascia the epicondyles of the humerus: it is strengthened by fibrous aponeuroses, derived from the pectoralis major and latissimus dorsi medially, and from the deltoideus laterally. On either side it gives off a strong intermuscular septum, which is attached to the corresponding supracondylar ridge and epicondyle of the humerus.
