Effector

Effectors are muscles or glands that bring about a response which helps restore optimum conditions.

A motor neurone carries impulses from the CNS to an effector.

The 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.

Motor neurons therefore carry instructions in the opposite overall direction from sensory neurons: from the CNS to an effector.
