Nervous System: Reaction Time - Stanford University

• Reflexes require at least two neurons, or nerve cells, to function. Sensory neurons take in information (input) from the outside world, whereas motor neurons give information (output) to muscles and joints. • Some reflexes are processed in the brain, while others are processed in the spinal cord • The 5 steps of a typical reflex arc are: a.
