What is a neurone?


Neurones are specialised cells, connected in their millions to form the nervous system which transmits information around the body.


They each consist of a cell body (the 'control centre' of the cell), dendrites (branching fibres that send messages to the cell body), and an axon (the nerve transmission fibre surrounded by a myelin sheath, and in the case of peripheral nerves by neurilemma) which leads to the axon terminals where impulses are transmitted from one neurone to another.
