WebThe reflex arc typically consists of five components: 1. The receptor is present in the receptor organ. 2. The sensory neuron conducts the nerve impulses towards the central nervous system (CNS). The CNS is comprised of the brain and the spinal cord. 3. The information is transferred from one neuron to other. 4. WebThe main stages in the reflex arc are as follows: 1. The sensory receptors detect the stimulus (Nerves in your fingers will detect the heat of the flame) 2. The sensory neurone passes this 'message' on via the relay neurone to the spinal cord in the central nervous system 3. The 'message' is then passed from the spinal cord to a motor neurone 4. cannot pair bluetooth speakers
