What does dorsiflexion refer to?

Dorsiflexion specifically refers to the action of raising the foot and pulling the toes toward the shin. This movement occurs at the ankle joint and is essential for activities like walking, where lifting the toes and foot helps clear the ground to avoid tripping.

In contrast, moving the foot downwards is known as plantarflexion, which is the opposite of dorsiflexion. Turning the foot outward is an action termed eversion, and decreasing the angle between the foot and leg is generally described as flexion, which can apply to various joints but in this context does not accurately describe dorsiflexion. Therefore, the definition provided in the correct choice clearly aligns with the standard anatomical terminology used to describe this specific movement of the foot.
