FINAL BODY SYSTEMS, STIMULUS & RESPONSE

1. What is the part of the nervous system that receives information?

• sensory receptors
• The brain
• The spine
• The central nervous system

2. Stimuli can include

• Mechanical stimuli
• Chemical stimuli
• Electromagnetic stimuli
• All of the above

3. Stimuli received are

• Changed into neurons
• Changed into electrochemical signals
• Changed into blood molecules and sent through the blood
• Absorbed into the bloodstream directly

4. The nervous system

• transmits signals between different parts of the body
• gives support to the structure of the body and holds the body up
• allows the body to take in oxygen
• all of the above

5. The neuron

• Is the cell that makes up the nervous system
• Passes an electrochemical signal along the axon
• Makes synapses with other neurons
• All of the above

6. Once the electrical signal travels to the brain

• It is eliminated
• It is processed and the brain may send signals to act or store it as memory
• It is converted to a soundwave
• It is retrieved

7. Repetition and review can help to

• Form short-term memory
• Form new neurons
• Form long-term memory

8. What is the most common type of blood cell?

• Red blood cell
• White blood cell
• platelets

9. Human systems are made up of

• tissue
• cells
• organs
• All of the above

10. A neuron is a

• Blood cell
• Bone cell
• Nerve cell
