A response sequence involves stimulus detection by receptors, impulse transmission via sensory neurones, chemical transfer to motor neurones, and effector activation.
A response involves a stimulus being detected by receptors, an impulse traveling along a sensory neurone, transmission via neurotransmitters to a motor neurone, and finally reaching an effector.
| Front | Stages for a response to be carried out |
|---|---|
| Back | Stimulus detected by receptor cells and electrical impulse sent along sensory neurone When electrical impulses reaches end of a neurone chemical known as neurotransmitters take the information the next neurone which sends an electrical impulse CNS processes information and sends impulses along motor neurone to an effector |
