Your body has miles of cable inside it
Similar to wires in a robot.

The nerves in the
body are like wires
In the robot.
They carry around
information.

Different parts of the
body are sent orders
to carry out.
The nerves have the following
things in common
with wires in a robot…

Insulation
Insulation is used to keep the message
in one piece and to help the message
travel quickly.

Branched
The wires are branched in the brain and in
effectors so that the messages can reach
different places at the same time.

The wires are long and thin so they can reach
every part of the body.

Sensory Neurones transmit nerve
impulses from sensory receptors all over
the body to the central nervous system.
Motor Neurones transmit nerve impulses from
the central nervous system to effectors
(muscles and glands) all over the body
Relay neurones links used to relay messages
from sensory neurone to motor neurone and
make up the brain and spinal cord usually
much smaller cells, with many connections.

Information from one neuron flows to
another neuron across a synapse.
The synapse is a small gap separating neurons.
