소흉근
소흉근, or the pectoralis minor, is a thin, triangular muscle located beneath the larger pectoralis major in the chest. It plays a crucial role in stabilizing the shoulder blade, or scapula, and assists in movements such as lifting the arm and pushing.
This muscle originates from the third to fifth ribs and attaches to the coracoid process of the scapula. Strengthening the 소흉근 can improve overall shoulder function and posture, making it important for athletes and individuals engaged in physical activities.
