Specification 4.5.2.1 · Paper 2
A nerve cell that carries electrical impulses.
Revise: Nervous System Structure & CoordinationThe impulse travels along a specialised nerve cell called a neurone. This arrangement lets information pass between a receptor, the central nervous system and the part of the body that will respond.

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.
When comparing neurones, state the direction of impulse travel: sensory neurones carry impulses to the CNS, whereas motor neurones carry impulses from the CNS.
Link each adaptation to its benefit. For example, a long axon carries impulses over long distances, while the myelin sheath insulates the neurone and increases transmission speed.

A specialised cell that transmits electrical impulses through the nervous system.
When 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 specialised cell that carries electrical impulses through the nervous system.
Revise: Nervous system structureThe nervous system allows the body to receive information from both its surroundings and its internal conditions. It uses specialised cells called neurones, which carry electrical impulses. These signals allow information to travel rapidly between sensory receptors, coordinating centres and effectors.

Revise: Treating Nervous System DamageNeurones carry impulses between these structures and the rest of the body, allowing us to sense changes and control responses. If the spinal cord is badly damaged, impulses may no longer pass between the brain and parts of the body below the injury. This can cause loss of movement or sensation.
