Reflexes
Reflexes are designed to protect you.
BUT HOW?

Nerve Cells or Neurons
• A neuron carries messages from one part
of the body to another
• Those messages or signals tell your body
what to do
These nerve impulses are actually small electric
currents that travel through your nerves.
What the relationship?

What are the three MAIN
parts of a neuron?
Turn and talk with someone next to you!
Draw and label the following:
Cell Body (soma)
Axon
Dendrites
Why did the
neurotransmitter cross
the road (synapse)?
To get to the
other dendrite!
But… if neurons never touch,
how does the action potential
(or nerve impulse) get between
the small space between the
end of one nerve cell and the
beginning of the next nerve
cell?
