Sits: supraspinatus / infraspinatus / teres minor / subscapularis (rotator cuff) Muscles from the axial skeleton to the pectoral girdle. Vertebral (medial) border of scapula near superior angle. Spinous processes c7 & t1 vertebrae (minor) Vertebral (medial) border of scapula near scapular spine (minor) Vertebral (medial) border of scapula inferior to scapular spine (major) Anterior surface of vertebral (medial) border of scapula. Elevates ribs when scapula is stationary assist in inhalation. Muscles from the axial skeleton to the humerus. Floor of the inter tubercular sulcus (i. e. bicipital groove) of humerus. Muscles from the pectoral girdle to the humerus. Dorsal surface of inferior angle of scapula. Anterior part: flexes arm (shoulder) and medially rotates arm (shoulder) Posterior portion: extends arm (shoulder) and laterally rotates arm (shoulder) 3 muscles in anterior compartment of arm: 1 muscle in posterior compartment of arm:
