The small and large rhomboid muscles (mm. rhomboidei minor et major) often grow together and form one muscle. The small rhomboid muscle originates on the lower part of the nuchal ligament, the spinous processes of the 7th cervical and 1st thoracic vertebrae and on the supraspinous ligament. The muscle bundles run obliquely from top to bottom and laterally, attaching to the medial edge of the scapula above the level of the spine of the scapula.
The large rhomboid muscle originates on the spinous processes of the II-V thoracic vertebrae. The muscle is attached to the medial edge of the scapula below the level of its spine, up to its lower angle. The rhomboid muscles, located under the trapezius muscle, cover the upper posterior serratus muscle and the muscle that straightens the trunk from behind.
Function: Brings the shoulder blade closer to the spine while simultaneously moving it upward.
Innervation: dorsal nerve of the scapula (CIV-CV).
Blood supply: transverse cervical artery, suprascapular artery, posterior intercostal arteries.
