Motor Neurone - GCSE Biology Definition

Motor neurones are specialised nerve cells that carry electrical impulses from the central nervous system (the brain and spinal cord) to effectors, such as muscles or glands.These impulses cause muscles to contract or glands to secrete substances, allowing the body to respond to stimuli. Motor neurones have long extensions called axons that help transmit signals quickly. They are an essential part of the nervous system and play a key role in coordinating both voluntary actions (like walking) and involuntary responses (like reflexes). Damage to motor neurones can affect muscle movement and control.
