Scapular downward rotation (or scapular superior rotation) is a rotary movement of the scapula – moving the inferior (lower) angle of the shoulder blade (scapula) medially and downwards – see Figure 1.
In anatomical terminology, a medial movement is one that moves part of the body closer to (medial to) the midline of the body.
The key muscles involved in this movement are the levator scapulae, the rhomboids, and the pectoralis minor. The pectoralis major and the latissimus dorsi also play a weak role.
