Your nervous system contains millions of nerve cells, called neurons. Neurons are highly specialised to transmit messages from one part of your body to another.
All neurons have a cell body and one or more fibres. These fibres vary in length from microscopic to over 1 metre. There are two different kinds of nerve fibres: fibres that carry information towards the cell body, called dendrites, and fibres that carry information away from it, called axons. Nerves are tight bundles of nerve fibres.
Neurons can be divided into three types:
Sensory neurons ::which pass information about stimuli such as light, heat or chemicals from both inside and outside your body to your central nervous system
Motor neurons ::which pass instructions from your central nervous system to other parts of your body, such as muscles or glands
Association neurons ::which connect your sensory and motor neurons
