Teres major is one of the seven scapulohumeral muscles that act around the glenohumeral joint to facilitate shoulder movement:

  • origin: caudal two thirds of lateral border and inferior angle of scapula
  • insertion: medial border of the intertubercular goove, which is the crest of lesser tubercle of humerus
  • innervation: lower subscapular nerve (C5/C6)
  • action: medial shoulder rotation and shoulder adduction
