Correctly identify the following neurons.
Type of Neuron
Action
1.
Your brain sends a message to the muscles in your bicep telling them to
contract so you can lift weight.
2.
Your brain sends messages to other neurons in your brain while you
process different smells, sounds, sights, feelings, and tastes.
3.
The type of neuron that brings information from your eye to your brain
4.
The type of neuron in the auditory nerve.
5.
Your brain sends a message to the muscles in around your eye to make
you blink.
6.
The type of neuron that relays messages through your spinal chord to
your brain.

Explain how an electrochemical message is received, passed through the neuron and
then sent to another neuron:
14. Explain how an electrochemical message is received, passed through the neuron and then sent
to another neuron:
Word Bank: Axon
Axon terminal
Dendrites (x2)
Impulse Neurotransmitter (x2)
First the ___________________________ receives a _____________________________ from another cell. This starts
an electrical _____________________________ in the neuron. When this happens, an electrical signal
travels through the ___________________________. When the electrical implulse gets to the end of the
axon, the __________ _________________________ releases ____________________________ to the next neuron. The
__________________________ of the next neuron receives the neurotransmitter and starts its own
electrical impulse.
Electrochemical How it works
Signal
Word Bank: Axon, Axon Terminal, Dendrite, Impulse, Neurotransmitter
15.
This is the chemical part of the electrochemical signal
16.
This is the electrical part of the electrochemical signal
17.
The part of the neuron receives the electrochemical signal.
18.
The part of the neuron that has an electrical impulse travel down it.
19.
The part of the neuron that releases electrochemical signals
