Neurone - GCSE Biology Definition

A neurone (also spelled neuron) is a specialised cell in the nervous system that carries electrical messages called nerve impulses. Neurones are found in the brain, spinal cord, and peripheral nerves, and they help us think, feel, and respond to our environment. Each neurone has three main parts: the cell body, which contains the nucleus; dendrites, which receive impulses from other neurones; and an axon, which carries impulses away to other neurones, muscles, or glands. By transmitting signals throughout the body, neurones allow for movement, sensation, memory, and many other vital functions.
