Smaller Pectoral Muscle (Noun)
Meaning
A skeletal muscle that draws down the scapula or raises the ribs.
Classification
Nouns denoting body parts.
Examples
- The smaller pectoral muscle, also known as the serratus anterior, enables strong downward movements of the scapula, as would occur in rowing motions.
- Movement of the smaller pectoral muscle, specifically the serratus anterior, helps stabilize the scapula against the chest wall as the arm lifts.
- Strengthening the smaller pectoral muscle through exercise is important for shoulder function and movement.
- Proper function of the smaller pectoral muscle allows for optimal scapular rotation, particularly in the upward phase of the throwing motion.
- Identifying the exact direction a weightlifter's shoulders are rotating often depends in part on observing the tension on the smaller pectoral muscle.
