Juan picks up a steel utensil and immediately drops it because it’s extremely hot. How does the reflex arc work to protect Juan from a worse burn?

a. In a reflex arc, the motor neuron carries the action potential from the spinal cord to the muscle.

Explanation:

In a reflex arc, the body reacts to stimuli before the impulse from the affected area gets to the brain. It does this by routing it to the spinal cord which then sends and impulse to the effector.

For this to happen, the sensory neuron in the part of the body involved will send an impulse to the spinal cord which would then send an action potential via a motor neuron to the muscle that needs to react.
