Latin muscle parts



Pectoral girdle muscle


In English, this muscle’s name is the small magician’s circle, or oblique angled parallelogram-shaped muscle. The term rhomboid is derived from the Greek rhombos meaning “a magician’s circle,” a shape represented by an oblique angled parallelogram, and the Greek ending eidos meaning “shape. The term minor comes from the Greek meion meaning “lesser.” As is typical in anatomical terminology, this comparative reference clues you into the fact that this is a smaller version of a similar shaped larger muscle.


Lower end of nuchal ligament and spinous processes of C7 and T1.


Medial margin of the scapula between the base of the scapular spine and the superior angle.


Adduction (retraction) of the scapula – the fibers of this small muscle assist the rhomboideus major and the middle fibers of the trapezius muscle in adducting the scapula. Elevation of the scapula – the fibers of the rhomboideus minor work in concert with the levator scapulae muscle to elevate the scapula. Working with the other scapular muscles, this muscle helps to stabilize the scapula and its associated glenoid cavity to improve the functional efficiency of the muscles working at the shoulder joint.

Nerve supply

Dorsal scapular nerve (C4 and C5)

Blood supply

Dorsal scapular artery, or its variation the deep branch of the transverse cervical artery and posterior perforating branches of the upper posterior intercostal arteries.
