Pectori

Pectori is a term that appears to be a misspelling or a less common variation of "pectorals," referring to muscles of the chest. The most prominent pectoral muscles are the pectoralis major and pectoralis minor, located in the upper chest. The pectoralis major is a large, fan-shaped muscle that originates from the clavicle, sternum, and upper ribs and inserts onto the humerus (upper arm bone). Its primary functions include adducting, medially rotating, and flexing the arm. The pectoralis minor is a smaller muscle situated beneath the pectoralis major. It originates from the ribs and inserts onto the coracoid process of the scapula (shoulder blade). The pectoralis minor acts to depress, protract, and downwardly rotate the scapula. Together, these muscles play a crucial role in various upper body movements, including pushing, throwing, and stabilizing the shoulder joint. They are often targeted in strength training exercises such as bench presses, push-ups, and dumbbell flyes. Injury to these muscles can occur during strenuous activity and may result in pain, weakness, or limited range of motion.
