Explanation:
Reflex actions happen through the reflex arc, which is a neural pathway that controls the reflexes. It acts on an impulse even before it reaches the brain. ... Immediately, the spinal cord sends back signals to the muscle through the motor neuron. The muscles attached to the sense organ move the organ away from danger.
