The rhomboid major is a skeletal muscle on the again that connects the scapula with the vertebrae of the spinal column. In human anatomy, it acts along with the rhomboid minor to keep the scapula pressed against thoracic wall and to retract the scapula toward the vertebral column.[1]

Structure

The rhomboid major arises from the spinous processes of the thoracic vertebrae T2 to T5 as well as the supraspinous ligament. It inserts on the medial border of the scapula, from about the level of the scapular backbone to the scapula's inferior perspective.[2]

Rhomboideus major muscle

The rhomboid major is considered a superficial again muscle. It is deep to the trapezius, and is situated immediately not as good as the rhomboid minor. As the phrase rhomboid suggests, the rhomboid major is diamond-shaped. The major in its name signifies that it's the larger of the two rhomboids.

Variation

The two rhomboids are on occasion fused into a unmarried muscle.[1]

Nerve supply

The scapular and circumflex arteries. Rhomboid major labelled at decrease left.

The rhomboid major, like the rhomboid minor, is innervated through the ventral primary ramus by the use of the dorsal scapular nerve (C5).[2]

Blood supply

Both rhomboid muscle tissues also derive their arterial blood provide from the dorsal scapular artery.

Function

The rhomboid major is helping to carry the scapula (and thus the upper limb) onto the ribcage. Other muscle mass that perform this serve as include the serratus anterior and pectoralis minor.

Both rhomboids (major and minor) additionally act to retract the scapula, pulling it in opposition to the vertebral column.

The rhomboids work collectively with the levator scapulae muscle tissue to elevate the medial border of the scapula, downwardly rotating the scapula with respect to the glenohumeral joint. Antagonists to this serve as (upward rotators of the scapulae) are the serratus anterior and lower fibers of the trapezius. If the decrease fibers are inactive, the serratus anterior and upper trapezius work in tandem with rhomboids and levators to elevate the entire scapula.

Clinical significance

If the rhomboid major is torn, wasted, or not able to contract, scapular instability might outcome. The implications of scapular instability caused by means of the rhomboid major include scapular winging throughout scapular protraction, excessive lateral rotation and despair of the scapula, as the antagonistic action via the rhomboid major is absent. With scapular instability, movement in the higher extremity is restricted as the scapula can not guide the desired motion of the arm and shoulders. Pain, discomfort, and limited range of motion of the shoulder are possible implications of scapular instability.

Treatment for scapular instability would possibly include surgical treatment followed by way of physical treatment or occupational remedy. Physical treatment would possibly consist of stretching and staying power workout routines of the shoulder. Pilates and yoga have been also advised as possible remedy and prevention of scapular instability.

Other animals

The muscular tissues of the shoulder can be labeled into three topographic units: the scapulohumeral, axiohumeral, and axioscapular groups. Stretching from the spine to the scapula, rhomboid major paperwork section of the latter group in conjunction with rhomboid minor, serratus anterior, levator scapulae, and trapezius. The trapezius has advanced one after the other, however the different muscle tissue on this team evolved from the first 8 or ten ribs and the transverse processes of the cervical vertebrae (homologous to the ribs). Functional demands have ended in the evolution of person muscle tissue from the basal unit shaped by means of the serratus anterior.

In primitive life paperwork, the main serve as of the axioscapular team is to keep an eye on the actions of the vertebral border of the scapula: fibers all in favour of the dorsal motion of scapula evolved into the rhomboids, those with ventral movement into serratus anterior, and the ones with cranial movements into levator scapulae.
