Different parts of the
body are sent orders
to carry out.

6. The wires are branched in the brain and in
effectors so that the messages can reach

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

8. 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.

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