C-7 through T-1 to vertebral border of scapula at the level of the spine of the scapula.
The rhomboid minor arises from the inferior border of the nuchal ligament, from the spinous processes of the seventh cervical and first thoracic vertebrae, and from the intervening supraspinous ligaments. Wiki
Medial border of scapula, superior to the insertion of rhomboid major muscle.
Together with the rhomboid major, the rhomboid minor retracts the scapula when trapezius is contracted. Acting as an antagonist to the trapezius, the rhomboid major and minor elevate the medial border of the scapula medially and upward, working in tandem with the levator scapulae muscle to rotate the scapulae downward. While other shoulder muscles are active, the rhomboid major and minor stabilize the scapula. Wiki
Innervation – Nerve control
Dorsal scapular nerve.
The nerve supply comes from the dorsal scapular nerve, with most of its fibers derived from the C5 nerve root and only minor contribution from C4 or C6. The rhomboid minor gets its arterial blood supply from the dorsal scapular artery. Wiki
Deep branch of transverse cervical artery.
The transverse cervical artery is one of three blood vessels that extend from the thyrocervical trunk, a larger artery located within the neck.
The serratus anterior muscle is a fan-shaped muscle. It is found at the lateral wall of the thorax, deep under the scapula and the pectoral muscles..
