Inside us
Neurons
Specialised cells turn signals into networks.
A neuron typically receives signals through branching dendrites and carries an electrical signal along an axon. Communication between cells often uses chemical messengers.
A closer look
The picture, in three parts.
Receive
Dendrites receive inputs.
Carry
An axon carries a signal away from the cell body.
Connect
Signals influence other cells at junctions called synapses.
