The brachial fascia (deep fascia of the arm) is continuous with that covering the deltoideus and the pectoralis major muscle by means of which it is attached above to the clavicle acromion and spine of the scapula; it forms a thin loose membranous sheath for the muscles of the arm and sends septa between them; it is composed of fibers disposed in a circular or spiral direction and connected together by vertical and oblique fibers.
