The three clusters of the pectoral muscles (pecs) are the pectoralis major, pectoralis minor, and the subclavius. The pectoralis major is the larger muscle responsible for arm movements, while the pectoralis minor lies beneath it and assists in stabilizing the scapula. The subclavius helps to stabilize the clavicle. Together, these muscles play crucial roles in upper body movement and stability.
