A reflex arc is a neural pathway that controls a reflex action. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord.his characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the reflex is carried out. Analysis of the signal takes place after action has been taken.
When the safety of an organism demands a very quick response, the signals may be passed directly from a sensory neuron, via a relay neurone, to a motor neurone motor: motor neurones carry messages out of the CNS to effector organs for instant, unthinking action. This is a reflex action.A reflex arc is the nerve pathway which makes such a fast, automatic response possible. It does not matter how brainy you are-you will always pull your hand away from a flame without thinking about it. It is in-built, or innate, behaviour, and we all behave in the same way.imple reflexes produce rapid involuntary responses to a stimulus. This ensures that an animal responds in the way most likely to result in its survival. Examples include: 1  moving towards and finding food.
