The Rhomboid Major and Rhomboid Minor are two separate muscles that work together to attach the scapula to the spine. The Rhomboid Minor is located above the Rhomboid Major and performs the same function and action within the body. The Rhomboids play a key role in the stability of the scapula and are important for any upper limb movement. The Rhomboid Major and Rhomboid Minor are classified as skeletal muscles and are located underneath the trapezius in the upper back. The Rhomboid Major is thinner and flatter and twice as wide as the Rhomboid Minor, however both muscles resemble the shape of a Rhomboid.

Rhomboid major vs minor

The rhomboid major is a skeletal muscle of the back that connects the scapula with the vertebrae of the spinal column. As the word rhomboid suggests, the rhomboid major is diamond-shaped. The major in its name indicates that it is the larger of the two rhomboids. The rhomboid major arises from the spinous processes of the thoracic vertebrae T2—T5 as well as the supraspinous ligament. It inserts on the medial border of the scapula , from about the level of the scapular spine to the scapula's inferior angle. The rhomboid major, like the rhomboid minor, is innervated by the ventral primary ramus via the dorsal scapular nerve C5. Both rhomboid muscles also derive their arterial blood supply from the dorsal scapular artery. The rhomboid major is considered a superficial back muscle. It is deep to the trapezius , and situated directly inferior to the rhomboid minor. The two rhomboids are sometimes fused into a single muscle. The rhomboid major helps to hold the scapula and thus the upper limb onto the ribcage. Other muscles that perform this function include the serratus anterior and pectoralis minor. Both rhomboids major and minor also act to retract the scapula, pulling it towards the vertebral column. The rhomboids work collectively with the levator scapulae muscles to elevate the medial border of the scapula, downwardly rotating the scapula with respect to the glenohumeral joint. Antagonists to this function upward rotators of the scapulae are the serratus anterior and lower fibers of the trapezius.

The dorsal scapular nerve originates from the ventral ramus of the spinal nerve root C5 and courses posterior inferiorly through the middle scalene muscles and between the posterior scalene, levator scapulae to which it also provides innervationand the serratus posterior superior. Regardless of its site of origin, the DSA passes through the brachial plexus, rhomboid major vs minor it joins and runs parallel to the dorsal scapular nerve.

Chances are, you've slumped over your desk more than once in your life. When this happens, a muscle group called the rhomboids, in particular, is affected—and not in a good way. The rhomboids play a very important role in good posture and a healthy upper back , even when you're away from your desk. The rhomboids are upper-back muscles that connect between your spine and each of your two shoulder blades scapulae. When they contract, they pull your shoulder blades together. The muscle fibers comprising the rhomboids run on a diagonal. The function of the rhomboid muscles is mainly to affix the scapula against the torso to allow a stable base from which the arm can move. Clinicians look at muscles in terms of their origin , insertion , nerve, and action.

Among muscles, the rhomboids are very popular. Unfortunately, these muscles are often popular for the wrong reasons. They are often associated with upper back pain, particularly from sitting for prolonged periods as well as generalized postural problems.

The deep muscles develop embryologically in the back, and are thus described as intrinsic muscles. The superficial and intermediate muscles do not develop in the back, and are classified as extrinsic muscles.

The Rhomboid Major and Rhomboid Minor are classified as skeletal muscles and are located underneath the trapezius in the upper back. Repeat this movement for 2 sets of 10 reps. Rhomboid Major and Rhomboid Minor Function The Rhomboid Major and Rhomboid Minor produce scapular retraction, elevation of the scapula and inferior rotation of the scapula. The Rhomboid Major and Rhomboid Minor work together to keep the scapula against the thoracic wall and to prevent scapular winging. GP Notebook.

The rhomboids work collectively with the levator scapulae muscles to elevate the medial border of the scapula, downwardly rotating the scapula with respect to the glenohumeral joint.
