Final answer:
Pointing the toes downward is known as plantar flexion, which is the action of bending at the ankle to lift the heel of the foot from the ground.
Step-by-step explanation:
Pointing the toes downward is known as plantar flexion. This motion involves bending at the ankle such that the heel is lifted, much like when you are standing on your toes.
During plantar flexion, you would be lifting the heel of the foot from the ground or pointing the toes downward. In contrast, dorsiflexion is the action of lifting the front of the foot so that the top of the foot moves toward the anterior leg.
Pronation involves the movement of the forearm in which the palm faces backward.
Therefore, the correct answer to the movement known as pointing the toes downward is c. Plantar flexion.
