What are the primary actions of the rhomboids in relation to the scapula?

The primary actions of the rhomboids in relation to the scapula are retraction and elevation. The rhomboid muscles, which consist of the rhomboid major and rhomboid minor, play an essential role in stabilizing the scapula against the thoracic wall.

When the rhomboids contract, they pull the scapulae towards the spine, which is the action of retraction. This retraction helps to keep the shoulder girdle stable during various movements of the upper limb. Additionally, the rhomboids assist in elevating the scapula, particularly when a person raises their arms or performs any actions that lift the shoulders.

A clear understanding of the rhomboids' function emphasizes their importance in maintaining proper posture and shoulder mechanics, especially during activities that involve pulling or lifting.
