These motions are critical because shoulder (glenohumeral) joint function depends heavily on the position and motion of the scapula. However, the shoulder girdle muscles themselves <strong>do not attach directly to the humerus<\/strong>, so they <strong>cannot cause movement at the shoulder joint<\/strong> (glenohumeral joint) directly.<\/p>\n\n\n\n<p>In contrast, <strong>shoulder joint muscles<\/strong>, such as the <strong>deltoid<\/strong>, <strong>pectoralis major<\/strong>, <strong>latissimus dorsi<\/strong>, <strong>teres major<\/strong>, and the <strong>rotator cuff muscles<\/strong> (supraspinatus, infraspinatus, teres minor, and subscapularis), <strong>do insert on the humerus<\/strong> and are responsible for its movement \u2014 such as <strong>flexion, extension, abduction, adduction, internal and external rotation<\/strong>.<\/p>\n\n\n\n<p>Therefore, while the shoulder girdle muscles play a <strong>supportive and stabilizing role<\/strong>, particularly by controlling scapular motion, <strong>they do not directly move the humerus at the shoulder joint<\/strong>, which makes the correct answer <strong>False<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The shoulder girdle muscles can move the humerus\/shoulder joint.
