6. A great analogy for how the nervous system sends signals through the body is...

A motor

A clock

Telephone lines

An electrical socket

7. The Nervous System can be divided into two categories based on whether you have control over certain movements or not. The two categories are...

Sympathetic

Autonomic

Automatic

Somatic

Submit

8. What is the job of a neuron? (choose the best answer)

To keep the body alive

To carry information from one part of the body to another

To make decisions as to how to react

To stop the signal

9. Name the three main body organs for the Nervous System:

Brain

Heart

Lungs

Spinal cord

A system of nerves

Submit

10. The three parts of the brain are...

Cerebrum

Axon

Cerebellum

Brain stem & medulla

Motor nerves

Neurons

Dendrite

Submit

11. Which three processes are controlled by the autonomic part of the nervous system?

Digestion of food

Running

Chewing

Writing

Breathing

The ongoing heartbeat

Submit

12. Which of the following is an example of reflex?

Throwing

Drinking water

Blinking

Reaching out to touch a hot object

13. The Nervous System can be divided into these two parts:

Brain Stem

Central Nervous System

Spinal Cord

Peripheral System

Cerebellum

Cerebrum

Medulla

Submit

14. What would happen if your body did not have neurotransmitters?

Your nerve cells could not communicate with one another.

Impulses could not travel along your nerve cells.

You would not be able to touch the objects that surround you.

Your nerve cells would begin dying off.

15. In a neuron, which part has the job of carrying the signal away from the cell body?

Axon

Dendrites

Motor nerves

Synapses

Impulses

16. a synapse is... (choose the three correct)

The gap between the axon and the next structure

A stimuli from the environment

The reaction to what's happening in the environment

The action chosen by the brain

Submit

17. Through the nervous system we are able to.... (choose the three correct)

React to stimuli

Interpret stimuli

Move

Take in oxygen

Break down food

Submit

18. What is the correct pathway of the signals (electrical impulses) through a nerve cell?

Cell body > dendrites > axon

Cell body > axon > dendrites

Dendrites > cell body > axon

Axon > dendrites > cell body

19. How are neurotransmitters different from the impulses that travel along the bodies of nerve cells?

The impulses are electrical; neurotransmitters are chemical

The impulses travel at a faster rate than neurotransmitters

The impulses send signals from the body to the brain; neurotransmitters send signals from the brain to the body

The impulses occur constantly; neurotransmitters are released only occasionally
