Your chest is composed of two muscle groups: the large pectoralis major, and the smaller pectoralis minor underneath. The flat, thick pec major originates in a broad sweep along the anterior surface of the clavicle, down the sternum, and from the cartilage of the ribs. It inserts into a much smaller area, the intertubular groove at the top of the humerus (upper arm).
The narrow, triangular pec minor originates from the upper and outer surfaces of three ribs and inserts into the coracoid process, a bony protrusion next to the shoulder joint.
The pec major is responsible for a number of actions involving the humerus, such as lifting the arm from the side (adduction), from the front (flexion), or turning it in an arm-wrestling motion (internal rotation). The pec minor has one major function, which is to stabilize the scapula.
