Serratus Magnus (Noun)
Meaning
Muscles that rotate the scapula and elevate the rib cage.
Classification
Nouns denoting body parts.
Examples
- The serratus magnus muscle originates from the surface of the upper borders of the outer margins of the first to eighth or ninth ribs and the intercostal fascia.
- The primary actions of the serratus magnus include rotating the scapula, elevating the rib cage, and assisting in movements such as throwing and pushing.
- During a push-up exercise, the serratus magnus muscle helps stabilize the scapula and rotate it upward, thereby elevating the rib cage and extending the arm.
- The serratus magnus muscle also contracts and relaxes in a coordinated manner to assist in activities that require forward arm movements, such as rowing or throwing.
- Strengthening the serratus magnus through exercises such as push-ups, dumbbell pullovers, and wall slides can improve athletic performance by increasing the range of motion and stability of the scapula and rib cage.
