    • A. 

      Enzyme

    • B. 

      Receptor

    • C. 

      Neurotransmitter

    • D. 

      Transporter protein

  • 3. 
    Which of the following is a function of the myelin sheath?
    • A. 

      Receives information from other neurons or from sense organs

    • B. 

      Increases the speed at which nerve impulses travel along an axon

    • C. 

      Releases neurotransmitters that can cross over to neighboring neurons

    • D. 

      Controls all cellular activity

  • 4. 
    Part of the neuron that releases neurotransmitters into the synaptic cleft.
    • A. 

      Axon hillock

    • B. 

      Dendrite

    • C. 

      Cell body

    • D. 

      Axon terminal

  • 5. 
    A disease that destroys the protective and insulating myelin covering the neurons in a process called demyelination.
    • A. 

      Multiple Sclerosis

    • B. 

      ALS

    • C. 

      Progressive Bulbar Palsy

    • D. 

      Primary Lateral Sclerosis

  • 6. 
    Neurotransmitters are stored in:
    • A. 

      Receptors

    • B. 

      Synaptic cleft

    • C. 

      Synaptic vesicles

    • D. 

      Post-synaptic neuron

  • 7. 
    When neurotransmitters are released into the synaptic cleft they bind to:
    • A. 

      The pre-synaptic neuron receptor sites

    • B. 

      The post-synaptic neuron receptor sites

    • C. 

      Re-uptake pumps

    • D. 

      Axon terminal

  • 8. 
    How does inactivation of neurotransmitters occur?
    • A. 

      Neurotransmitters are degraded by being broken down by enzymes or reused by active re-uptake.

    • B. 

      Neurotransmitters eventually dissolve on their own.

    • C. 

      Neurotransmitters dissipate into the brain matter and become useless.

    • D. 

      Neurotransmitters bind together so they are too big to fit into receptor sites and are rendered inactive.

  • 9. 
    Some medications for the treatment of Schizophrenia block Dopamine receptors. What does that indicate about the role of Dopamine in Schizophrenia?
    • A. 

      There is too little Dopamine in the brains of Schizophrenic people.

    • B. 

      The receptors are faulty for Dopamine in the brains of Schizophrenic people.

    • C. 

      Schizophrenic patients cannot produce enough Dopamine.

    • D. 

      There is too much Dopamine in the brains of Schizophrenic people. Drugs that block Dopamine receptors will decrease the action of Dopamine.

  • 10. 
    If a medication inhibits the re-uptake of a neurotransmitter, what does that mean?
    • A. 

      It means that it will decrease the level of the neurotransmitter available in the synaptic cleft and therefore decrease its action.

    • B. 

      It means that it will increase the level of the neurotransmitter available in the synaptic cleft and therefore increase its action.

    • C. 

      It means that the re-uptake of the neurotransmitter will be more efficient.

    • D. 

      It means that the re-uptake process will help facilitate more neurotransmitter storage.

  • 11. 
    Depression, suicide, impulsive behavior, and aggressiveness all appear to involve certain imbalances in:
    • A. 

      Serotonin

    • B. 

      Acetylcholine

    • C. 

      Dopamine

    • D. 

      GABA

  • 12. 
    The loss of this neurotransmitter in certain parts of the brain causes the muscle rigidity typical of Parkinson’s disease.
    • A. 

      Serotonin

    • B. 

      Norepinephrine

    • C. 

      Dopamine

    • D. 

      Glutamate

  • 13. 
    This substance delivers a sedative punch once it goes into the brain. It interacts with GABA receptors and drives them to be more inhibitory.
    • A. 

      Ecstacy

    • B. 

      Alcohol

    • C. 

      LSD

    • D. 

      Marijuana

  • 14. 
    This substance binds to Serotonin receptors but not always in the same way. This substance can inhibit or excite these receptors. This is why it has complex sensory effects.
    • A. 

      LSD

    • B. 

      Cocaine

    • C. 

      Heroin

    • D. 

      Methamphetamine

  • 15. 
    This substance binds to the opiate receptors. This mechanism turns off Dopamine inhibition and Dopamine gets released into the synapse. This generates feelings of sedation.
    • A. 

      Alcohol

    • B. 

      LSD

    • C. 

      Cocaine

    • D. 

      Heroin
