Which muscles are involved in moving the scapula?

• A. Rhomboids, serratus anterior, and trapezius
• B. Rectus abdominus and iliopsoas
• C. Deltoids and triceps
• D. Adductors and gluteus maximus

Answer: (A)

The muscles involved in moving the scapula include the rhomboids, serratus anterior, and trapezius because they play key roles in shoulder movements and stabilizing the scapula. The rhomboids, located between the spine and the scapula, are responsible for retracting and elevating the shoulder blade, pulling it closer to the spine. The serratus anterior, which is positioned along the side of the chest, aids in protracting the scapula, allowing for upward rotation, which is particularly important for raising the arms above the head. The trapezius is a large muscle covering the upper back and neck; it extends from the base of the skull to the mid-back and is critical for various scapular movements, such as elevation, retraction, and rotation. Together, these three muscles enable a full range of motion around the scapula, facilitating various arm movements needed for daily activities and sports. This coordinated action is vital for maintaining proper shoulder function and biomechanics.
