If Mr. Jones' leg is turned outward so that his toes are pointing away from his body, what is this movement called?

The movement described, where Mr. Jones' leg is turned outward with the toes pointing away from the body, is known as external rotation. This term refers to the rotation of a limb around its long axis, moving the body part away from the midline. In this case, when the leg is rotated externally, the foot and toes move laterally compared to the body's center.

Understanding the context of the other options helps clarify why external rotation is the correct answer. Internal rotation, for example, would involve turning the leg toward the midline, which is the opposite of external rotation. Abduction refers to moving a limb away from the body's midline, usually in a lateral direction, while adduction is the movement toward the midline. Therefore, in this scenario, the correct terminology and understanding of the movement confirm that it is indeed external rotation.
