What movement occurs during upward rotation of the scapula?

During upward rotation of the scapula, the movement of the scapula is characterized by it moving upward and laterally. This specific motion occurs as the shoulder girdle facilitates arm elevation, such as during overhead activities. When the scapula rotates upward, the inferior angle moves away from the spine while the superior border tilts upwards, resulting in the lateral movement.

This upward rotation is crucial for the proper biomechanics of the shoulder joint, allowing the glenohumeral joint to achieve a greater range of motion. It enables arms to be raised overhead effectively, maintaining alignment and stability throughout shoulder movements. Scapulohumeral rhythm incorporates this upward rotation to ensure that the shoulder functions optimally in various activities requiring arm elevation.
