Revise: Nervous System ComponentsWhen an appropriate stimulus affects a receptor, the receptor initiates information in the form of an electrical impulse in a sensory neuron.
Write the pathway in the correct direction: stimulus → receptor → sensory neuron → CNS → motor neuron → effector → response.
Do not say that receptors carry impulses to the CNS: receptors detect stimuli, while sensory neurons carry the resulting electrical impulses.
