How the brain works

Neurons 2

Cell body
This contains the cell parts that every cell needs to stay alive, such as the nucleus, where the DNA is found.

Axon
This long, cable-like tail on the neuron conducts an electric signal and transmits it towards the next cell.

Dendrites
This short ‘protrusion’ from the cell body contains receptors to pick up signals transmitted by the axons of other neurons.
