Pectoral muscles (colloquially referred to as ” pecs “) are the muscles that connect the front of the human chest with the bones of the upper arm and shoulder. Deep muscles of the chest, including pectoralis minor, serratus anterior, and subclavius (Gray 1918)
Pectoralis major muscle (Musculus pectoralis major) The pectoralis major is a paired, superficial muscle located on the anterior surface of the thoracic cage.If you’re a gym lover, you’ll hear these muscles also being referred to as the pecs muscles.The pectoralis major has a broad origin, based on which it is divided into three parts: clavicular part, sternocostal part and abdominal part.
The pectoralis major (from Latin pectus ‘ breast ‘) is a thick, fan-shaped muscle, situated at the chest of the human body. It makes up the bulk of the chest muscles and lies under the breast. Beneath the pectoralis major is the pectoralis minor, a thin, triangular muscle.
Chest Structure And Function 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.
The pectoralis major is the most superficial muscle in the pectoral region. It is large and fan shaped, and is composed of a sternal head and a clavicular head. The pectoralis major is active in deep or forced inspiration, but not expiration. Origin.

Looking at the diagram you can see that if the pec minor is too tight and short, it will pull on the top of the …
Pectoralis Major Muscle lies in front of chest wall. The inner or medial tendon of the muscle originates from surface of breastbone (sternum) and collarbone (clavicle). The lateral or outer end of the muscle continues as lateral (outer) tendon and attaches to humerus. The inflammation of the Pectoralis Major Muscle and its Tendon is quite rare.
The pectoral tendon attaches the pec major muscle to your humerus or arm bone. The pec major is a very powerful muscle. Pectoral tendons are usually ruptured or torn in weight lifters during bench pressing. Traumatic injuries in sports can also result in a pec tendon tear. Surgery is often needed to repair complete pec tears. The recovery after surgery often means that this is a season-ending …
