Specification 4.5.2.1 · Paper 2
A neurone that carries electrical impulses from a receptor to the central nervous system.
Revise: Nervous System Structure & CoordinationElectrical impulses from receptors travel to it along sensory neurones. The CNS receives and processes the information, then coordinates a suitable response. Impulses travel away from the CNS along motor neurones to effectors.
In a pathway question, name the sensory neurone carrying impulses to the CNS and the motor neurone carrying impulses from the CNS to the effector.
Give the full pathway in order: stimulus → receptor → sensory neurone → relay neurone → motor neurone → effector → response.
When comparing neurones, state the direction of impulse travel: sensory neurones carry impulses to the CNS, whereas motor neurones carry impulses from the CNS.

A neurone that carries electrical impulses from sensory receptors towards the central nervous system.
Revise: Neurones and SynapsesWhen stimulated, receptors initiate electrical impulses in a sensory neurone. In this way, they convert information about a change into a signal that the nervous system can transmit.
A neurone that carries an electrical impulse from a receptor towards the central nervous system.

A neurone that carries electrical impulses from a sensory receptor towards the central nervous system.
Revise: Nervous system structureRelay neurones within the central nervous system can connect incoming sensory neurones to outgoing motor neurones. This pathway shows where each component fits; how the components coordinate a complete response is considered separately.
