When the body is in a prone position, what is the status of the pectoralis major?

When the body is in a prone position, the pectoralis major is considered to be in an anterior status. This muscle is located on the front of the chest and extends from the clavicle, sternum, and ribs to the humerus. In the prone position, the chest is facing downward, which places the pectoralis major in a position on the front side of the body relative to the surface on which a person is lying.

Understanding the orientation of muscles in relation to body positioning is essential in fields like massage therapy and anatomy. This knowledge helps practitioners to effectively assess and target muscular structures during treatment. The anterior position of the pectoralis major is crucial for recognizing its role in movements such as flexion, adduction, and medial rotation of the arm, and for effectively implementing techniques that engage this muscle when treating clients in various postures.
