2.2 Reflex Actions

Peripheral nervous system (PNS) In some cases when the Sensory neurons are stimulated we need a quick reaction which wouldn't happen if we sent messages all the way round the CNS. This is why animals have the Relay Neuron (Interneurone) to speed up our reactions

Sensory and Relay neurone connect through synapses, as do the Motor neuron
