Rhomboids - Muscle Physiology & Functional Anatomy

 

Rhomboids Muscle

 

 

Anatomy

 

Origin:

  • Rhomboid Major

    • Spinous processes of the T2 to T5 vertebrae

  • Rhomboid Minor

    • Nuchal ligaments and spinous processes of C7 to T1 vertebrae


Insertion:

  • Rhomboid Major

    • Medial border (below spine) of the scapula, inferior to the insertion of rhomboid minor muscle

  • Rhomboid Minor

    • Superior (below spine), medial border of the scapula (below levator scapulae, superior to the insertion of rhomboid major muscle)



Major Artery:

  • Dorsal scapular artery

 

Neural Innervation:

  • Dorsal scapular nerve (C4-C5)

 

Trigger Points:

Trigger Points of the Rhomboids

 

Physiology

 

Concentric Functions:

  • Adduction (retraction) & downward rotation of the scapula

 

Eccentric Functions:

  • Decelerates scapular abduction (protraction) and upward rotation

 

Isometric Function:

  • Dynamically stabilizes the scapula which helps the rotator cuff enough stability to work efficiently
