The rhomboids are a collective group of muscles formed by the rhomboid major and minor. The rhomboids are important in upper limb movement and stability of both the shoulder girdle and scapula. Both rhomboids receive innervation from the dorsal scapular nerve, and their vascular supply the dorsal scapular artery. Variants in rhomboid musculature have been found but are very rare. While surgeries of the rhomboid musculature are infrequent, winged scapula and rhomboid palsy are clinical pathologies associated with the rhomboids.[1]

FAQs
Rhomboid Major Origin And Insertion? ›
Origin & Insertion
What is the origin insertion and action of the rhomboid major? ›It originates from the spinous processes of the thoracic vertebrae T2-T5 and supraspinous ligament; it inserts onto the lower portion of the medial border of the scapula. It acts together with the rhomboid minor to keep the scapula pressed against thoracic wall and to retract the scapula toward the vertebral column.
What is the origin and insertion of the rhomboid minor? ›The rhomboid minor is an extrinsic muscle of the shoulder. It is located deep to the trapezius, and superior to the rhomboid major. Attachments: Originates from the spinous processes of C7-T1 vertebrae. Attaches to the medial border of the scapula, at the level of the spine of scapula.
What is the action of the rhomboid major location? ›It is located deep to the trapezius, and inferior to the rhomboid minor. Attachments: Originates from the spinous processes of T2-T5 vertebrae. Attaches to the medial border of the scapula, between the scapula spine and inferior angle. Actions: Retracts and rotates the scapula.
What is the origin of the rhomboid nerve? ›The rhomboid major, rhomboid minor, and levator scapulae muscles are created from a paraxial mesoderm origin and are innervated by the anterior (ventral) primary rami of C5. The source of the anterior motor roots of the cervical region is the basal plate region of the spinal cord.
What happens when the rhomboid is injured? ›A rhomboid strain causes pain in your upper back between your shoulder blades and your spine. A spasm feels like a knot or tightness in the muscle. You may have pain when you move your shoulders or when you breathe.
What causes knots in the rhomboid muscle? ›A rhomboid muscle strain or spasm is usually caused by overuse of your shoulder and arm. This can happen from: Overhead activities, like serving a tennis ball or reaching to put objects on a high shelf. Rowing.
What is the difference between the rhomboid and the trapezius? ›The middle trapezius and rhomboid muscles are responsible for retraction of the scapula, but the middle fibres of the trapezius function as pure scapular retractors, whereas the rhomboids act both to retract the scapula and to rotate it to depress the glenoid fossa.
Why does my rhomboid major hurt? ›Causes of Rhomboid Muscle Pain
Pain in your rhomboid muscle or your upper back and shoulders can be caused by many things, including an injury, a strain, or overuse. Rhomboid muscle pain can happen from: Bad posture, especially sitting hunched at your computer for too long. Rowing motions.
Severe referred rib pain to the side and front of your chest can be caused by nerve and muscle inflammation at the facet joints of your middle-back, rhomboid muscles or ligaments between your shoulder blades or from nerves in your lower neck or mid-back.
What is the function of the rhomboid major muscle? ›
Function. The main action of the rhomboid muscles is scapular retraction around the scapulothoracic joint. Scapular retraction is a simultaneous sliding of the scapula superiorly and medially along the trunk. This superomedial movement of the scapula rotates the glenoid cavity inferiorly, dropping the shoulder girdle.
Can rhomboid pain radiate to arm? ›Spasms of the rhomboids refer pain to a local and limited area, as well as down the lateral aspect of the arm, and are often accompanied by trigger points in levator scapulae, trapezius, and pectoralis major and minor.
How do you sleep with rhomboid pain? ›Sleeping with rhomboid pain can be difficult, but finding a position that reduces strain on the affected area can make a significant difference. On your back: This position often supports your spine and neck the most. On your side: If you prefer sleeping on your side, align your head and neck with your spine.
What is the origin and insertion of the trapezius major muscle? ›Trapezius Attachments
It originates on the occipital bone, the ligamentum nuchae, and the spinous processes of T01–T12. The trapezius inserts on the lateral third of the clavicle, as well as the acromion and scapular spine of the scapula.
Origin of the latissimus dorsi is from spinous processes of thoracic T7–T12, thoracolumbar fascia, iliac crest and inferior 3 or 4 ribs, inferior angle of scapula and insertion on floor of intertubercular groove of the humerus.
What is the origin and insertion of the scapular muscles? ›Origin and insertion
Levator scapulae originates from the transverse processes of the first four cervical vertebrae. The muscle fibers descend laterally to insert at the superior angle and medial border of scapula, between the superior angle and base of the spine of scapula.
The teres major muscle originates on the dorsal surface of the inferior angle and the lower part of the lateral border of the scapula. The fibers of teres major insert into the medial lip of the intertubercular sulcus of the humerus.
