Connective Tissue of Pectoralis Major Muscle: Anatomical Study

Through systematic ultrasound visualization of the pectoralis major muscle, we seek to directly visualize and characterize the different intra- and extra-muscular connective structures of the muscle - Delto Pectoral Tendon (DPT) , Distal Pectoralis Major Tendon (PMT), Anterior Deltoid Tendon (ADT), Anterior Pretendinous Lamina of the Pectoralis Major (ALPM), Posterior Pretendinous Lamina of the Pectoralis Major (PLPM) and Deep Fascia of the Pectoral Major (DFPM) - constituting its connective skeleton, with particular attention to its distal portion near the humerus and on the search for this DPT tendon.
