Rhomboids – Functional Anatomy

Rhomboid Muscles

The rhomboids attach the upper thoracic and lower cervical vertebrae to the scapula through the ribs and clavicle.

The rhomboids, which are usually thought of as retracting the scapula, are surprisingly active in stabilizing the scapula during abduction and flexion of the humerus. They also retract and stabilize the scapula in labored breathing. There are no statistically significant variations, other than occasionally being fused into one muscle.

Rhomboid Minor

Origin: the lower nuchal ligament, the supraspinous ligaments, and spinous processes along C7 and T1.

Insertion: the medial border of the scapula near the root of the spine of the scapula

Function: retraction of the scapula, assist in downward rotation of the scapula, stabilizes scapula during flexion and abduction

Rhomboid Major:

Insertion: the medial border of the scapula near the root of the spine of the scapula

Function: retraction of the scapula, assist in downward rotation of the scapula, stabilizes scapula during flexion and abduction
