PECTORALIS MINOR Meaning and
Definition
-
The pectoralis minor is a skeletal muscle located in the upper chest region of the body. It is situated beneath the pectoralis major muscle, and together they form the pectoral muscles of the chest. The pectoralis minor is a flat, triangular-shaped muscle that connects the third, fourth, and fifth ribs near their coastal cartilages to the coracoid process of the scapula, which is a bony projection on the shoulder blade.
The primary function of the pectoralis minor is to aid in the movement and stability of the scapula. It assists in several movements of the shoulder joint, including protraction (forward movement), downward rotation, and stabilization of the scapula. This muscle also plays a role in the elevation of the rib cage during forced inhalation, assisting in the expansion of the thoracic cavity to increase lung capacity.
In addition to its functional role, the pectoralis minor is important in maintaining good posture. When it is overly tight or shortened, it can cause an imbalance in the shoulder girdle, leading to rounded shoulders and a forward head posture. It is therefore important to maintain the flexibility and strength of the pectoralis minor through stretching and strengthening exercises to promote proper alignment and prevent postural issues.
