Read the wording for your board, then hide it and explain Stimulus–response pathways in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: Pearson Edexcel
Receptors detect a stimulus and generate an action potential in a sensory neurone, which carries impulses to the CNS, where relay neurones pass signals to motor neurones that transmit impulses to effectors.
