Reflex arc. Reflex reactions in humans are controlled by the reflex arc. 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 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.hen 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 for instant, unthinking action.
