Your neurons can be divided into three types: Nerves are tight bundles of nerve fibres. 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. These fibres vary in length from microscopic to over 1 metre. Neurons are highly specialised to transmit messages from one part of your body to another.Īll neurons have a cell body and one or more fibres. Your nervous system contains millions of nerve cells, called neurons. Neurotransmitters: Chemicals released by one neuron to excite a neighbouring one Nerve impulses: Electrical signals carrying messages Neurons: Messenger cells in your nervous system Function: To transmit messages from one part of your body to another
