The supraspinatus is named for its location on the posterior aspect of the scapula above the spine. What is its action?Group of answer choicesto flex and adduct the humerus and to act as a synergist of the pectoralis majorto extend and medially rotate the humerus and to act as a synergist of the latissimus dorsito initiate abduction of the arm, to stabilize the shoulder joint and to help prevent downward dislocation of the humerus.to help hold the head of the humerus in the glenoid cavity and rotate the humerus laterallyNext

This group of muscles are commonly known as the 'rotator cuff', responsible for increasing stability at the glenohumeral joint and agonists for shoulder abduction, shoulder lateral rotation and shoulder medial rotation.Group of answer choicesteres minor, teres major, serratus anterior, supraspinatusteres minor, infraspinatus, teres major, latissimus dorsipectoralis major, pectoralis minor, latissimus dorsi, teres majorsubscapularis, supraspinatus, infraspinatus, teres minor

Identify the true statement about the trapezius muscle  it can protract the scapula   it can abduct the humerus   it cannot work in synergy with the serratus anterior   it can medially or downwardly rotate the scapula   it can laterally or upwardly rotate the scapula
