What are the actions associated with the rhomboid minor?

The rhomboid minor plays a significant role in the movement of the scapula. Its primary actions include retraction, which is the movement of the scapula toward the spine, and downward rotation, which involves rotating the scapula so that the glenoid cavity faces downward. These actions help stabilize the shoulder girdle and contribute to the overall movement and positioning of the scapula during various arm activities.

Understanding these functions highlights the importance of the rhomboid minor in maintaining proper posture and assisting in upper limb movements. By effectively retracting the scapula, the rhomboid minor helps ensure that the shoulder remains in a balanced position, allowing for efficient use of the upper extremities while engaging in activities such as lifting, pulling, or reaching.
