What is the action of evert?

The action of eversion refers to the movement of turning a body part outward or away from the midline of the body. This term is commonly used in anatomy, particularly when describing movements of the foot. For example, during eversion of the foot, the sole turns away from the opposite foot, causing the ankle to roll outward. Understanding this action is crucial in various medical and physical therapy contexts, especially in diagnosing and treating lower limb injuries or conditions.

The other options describe different movements: turning inward is described by inversion, bending typically refers to flexion, and extending means to straighten or increase the angle of a joint. Clarity about these terms is important for accurate communication in medical settings.
