Which movement would be involved if one were to "step on the gas pedal"?

1. Dorsiflexion

2. Plantar flexion

3. Inversion

4. Eversion

The correct answer is: Plantar flexion

Plantar flexion is the correct movement involved when "stepping on the gas pedal." This action occurs when the toes and the foot are pointed downward, which engages the calf muscles and extends the ankle joint. In practical terms, this is the motion used to accelerate a vehicle, as you push down on the pedal. Dorsiflexion, on the other hand, involves lifting the toes upward toward the shin, which is not relevant to pressing the gas pedal. Inversion refers to the movement of the sole of the foot inward, while eversion involves the sole turning outward. Neither of these movements is applicable in this context. Therefore, plantar flexion is specifically linked to the action of pushing down on the gas pedal, making it the correct answer.
