Action of Rhomboid Minor
Adducts and downwardly rotates scapula
The rhomboid minor is a small, triangular-shaped muscle located in the upper back region between the shoulder blades. It is one of two rhomboid muscles, the other being the rhomboid major. The rhomboid minor is responsible for retracting or pulling the scapula (shoulder blade) medially towards the spine, and also helps to elevate the scapula towards the ear.
When the rhomboid minor contracts, it helps to stabilize the scapula and keep it in a proper position during movement of the arm. This is important for activities such as reaching, pulling, or lifting objects. It also helps to maintain good posture by keeping the shoulders back and down, and preventing rounding or hunching of the upper back.
Overall, the action of the rhomboid minor is closely related to the movement and stability of the scapula, which is an important component of proper shoulder function and posture.
