Q1 Which of the following is a neuron’s job?
  1. to send information to other neurons
  2. to send information to your muscles
  3. to carry messages from your brain to your spinal cord
  4. all of the above
Q2 An incoming signal enters a neuron through its
  1. axon.
  2. myelin sheath.
  3. dendrites.
  4. soma.
Q3 What does the axon of a neuron do?
  1. protect the dendrites
  2. carry signals away from the soma
  3. insulate the myelin sheath
  4. process the information it receives
Q4 True or False: The axon of one neuron always touches the dendrites of another neuron.
  1. True
  2. False
Q5 What does the myelin sheath do?
  1. protect the soma
  2. carry signals into the dendrites
  3. insulate the axon
  4. process the information it receives
Q6 Neurotransmission can best be described as a(n)
  1. physical change.
  2. nuclear reaction.
  3. electrochemical process.
  4. electromagnetic field.
Q7 Neurotransmitters can best be described as
  1. electrical charges.

  3. actions.
  4. reflexes.
Q8 True or False: A neuron’s response is all-or-nothing.
  1. True
  2. False
Q9 Which of the following correctly describes neurotransmission?
  1. An action potential travels down the axon and triggers the release of neurotransmitters. The neurotransmitters cross the synapse, and another action potential begins.
  2. A neurotransmitter travels down the axon and triggers the release of an action potential. The action potential crosses the synapse, and another neurotransmitter begins.
  3. The synapse travels down the axon and triggers the release of an electrical impulse. The electrical impulse crosses the neurotransmitter, and another synapse begins.
  4. A neuron sends a chemical signal down its axon. The axons touch the dendrites of another neuron, and the signal continues.
