Fascial planes anterior to left shoulder joint
A layer of fascia (6)extends laterally from the short head of the biceps across the shoulder joint. This layer blends with a fascia, aponeurotic in character, which continues upward from the insertion of the pectoralis major (18). The tendon of insertion of the subscapular muscle (4) is covered by a combination of the subscapular fascia. This layer has been reflected superiorly (3).
