It is located deep to the trapezius, and superior to the rhomboid major. Attachments: Originates from the spinous processes of C7-T1 vertebrae. Attaches to the medial border of the scapula, at the level of the spine of scapula. Actions: Retraction and rotation of the scapula. Innervation: Dorsal scapular nerve.

Learn More Frequent questions What is the rhomboid minor muscle? The rhomboid minor is an extrinsic muscle of the shoulder that plays a key role in scapular movement. It is situated beneath the trapezius and above the rhomboid major. Where does the rhomboid minor originate from? The rhomboid minor originates from the spinous processes of the C7 and T1 vertebrae. This anatomical position contributes to its function in scapular movement. What are the primary actions of the rhomboid minor? The main actions of the rhomboid minor include retraction and rotation of the scapula. These movements are essential for proper shoulder mechanics and stability. Which nerve innervates the rhomboid minor muscle? The rhomboid minor is innervated by the dorsal scapular nerve. This nerve is crucial for the muscle's motor function and overall shoulder movement. What is the blood supply to the rhomboid minor? The rhomboid minor receives its blood supply from the dorsal scapular artery. This vascular supply is vital for the muscle's health and function.
