Which muscle stabilizes the scapula, drawing it downward and forward?

The pectoralis minor is the correct choice for stabilizing the scapula and drawing it downward and forward. This muscle is located underneath the pectoralis major and plays a crucial role in shoulder movement and stability. When the pectoralis minor contracts, it pulls the scapula towards the rib cage, which helps position the shoulder joint and contributes to the proper function of the upper limb.

The gluteus medius primarily functions in hip stabilization and does not influence scapular movement. The soleus is a muscle located in the calf that is primarily involved in plantar flexion of the foot, unrelated to scapular positioning. Lastly, the rectus abdominis is a core muscle that aids in trunk flexion and stability but does not have a direct role in the movement or stabilization of the scapula. Thus, the pectoralis minor is the muscle specifically responsible for the actions described in the question.
