Which of the following muscles moves the scapula?

The rhomboid muscle plays a crucial role in the movement of the scapula. Specifically, it is responsible for retracting the scapula, which means it pulls the shoulder blades together towards the spine. This action is essential for maintaining proper posture as well as facilitating various upper body movements, such as pulling or lifting.

In contrast, while the latissimus dorsi and deltoid muscles are important for various upper body movements, their primary functions are not focused specifically on the movement of the scapula. The latissimus dorsi is primarily involved in extending, adducting, and internally rotating the shoulder. The deltoid, on the other hand, is primarily responsible for shoulder abduction and flexion.

As for the triceps, its main function is to extend the elbow joint and it does not contribute directly to the movements of the scapula. Therefore, the rhomboid stands out as the correct answer due to its specific role in scapular motion.
