su·pra·spi·na·tus (mus·cle)

intrinsic (scapulohumeral) muscle of shoulder joint, the tendon of which contributes to the rotator cuff; origin, supraspinous fossa of scapula; insertion, greater tuberosity of humerus; action, initiates abduction of arm; its tonic contraction helps to hold the head of the humerus in the shallow glenoid fossa; nerve supply, suprascapular from fifth and sixth cervical.


Etymology: L, supra, above + spina, spine
a muscle originating in the supraspinous fossa and inserting in the greater tubercle of the humerus. It functions to abduct the humerus.
