The reflex arc includes the sensory neuron (sensory intake) to the motor neuron (motor response). This two neuron arc is the fastest. Many times an interneuron at the level of the spinal cord is involved. It passes information to the brain more slowly. It is like an "incident report".
Reflex responses are controlled by the spinal cord and brainstem. The spinal cord is responsible for generating motor responses to sensory input without involving the brain in order to produce quick reflex actions.
The three-neuron arc is the most common and consists of the afferent neurons, interneurons, and the efferent neurons. Afferent neurons conduct impulses to the CNS from the receptors. Efferent neurons conduct impulses from the CNS to effectors (muscle or glandular tissue). Two-neuron arc is the simplest form, fastest responding and consists of afferent and efferent neurons. Example is the knee-jerk reflex.

Nerves connect to the brain and spinal cord in order to communicate with the rest of the body.

A reflex. Reflexes are processed by the spinal cord in order to provide a quicker reaction than would be achieved if the signal travelled all the way to the brain and back.

The order of a visceral reflex involves sensory receptors detecting a stimulus, which then sends signals via afferent neurons to the central nervous system. The central nervous system processes the information and sends signals through efferent neurons to the effector organs, resulting in a response to the stimulus.
The withdrawal reflex is activated within your nervous system when you touch a hot surface. This reflex causes your muscles to quickly pull your hand away in order to avoid further damage from the heat. The heat sensors in your skin send a signal to your spinal cord, which then sends a message to your muscles to react.
