a to d The anterior view of the humerus after the deltopectoral approach and resection of the pectoralis major tendon. The insertion site of the tendons on the humerus in four different specimens (a, c, and d: left side; b: right side) with the presence of the distal teres major slip. Note the separate (distal) but continuous (mediolateral) insertion of the distal teres major slip within a common epimyseal sheet around the TM. LBT, long biceps tendon; LD, latissimus dorsi; PM, pectoralis major; TM, teres major; dTMs, distal teres major slip
