1. When a neuron is at rest, the inside of the cell contains more than .A. K+; Na+.B. Ca++; Na+.C. Na+; K+.D. Fe++; Fe+++.E. Na+; Ca++.
2. The connective tissue wrapping around an entire nerve is called:
3. Neuroglia cells in the CNS are responsible for all except which one of thefollowing:
4. A neural impulse will proceed through a neuron in what anatomical sequenceonce a receptor is stimulated:
5. A motor nerve consists of:A. dendrites.B. axons.C. cell bodies.D. All of the above.E. None of the above.
6. The Na/K pump:
D. All of the above.E. None of the above.7. Arrange the following events in the correct order of occurrence. An actionpotential involves:1. increased K+ permeability; decreased Na+ permeability.2. resting membrane potential reestablished.3. threshold stimulus applied.4. increased Na+ permeability.5. K+ moves out.6. Na+ moves into cell7. depolarization occurs.8. repolarization occurs.The correct sequence is:
8. Neuronal cell bodies are located in the CNS within:
9. If a neuron were experimentally placed in conditions where intracellularpotassium were depleted, which of the following Is a logical consequence?A. the neuron would hyper polarize.B. the intracellular charge would become more positive.C. the neuron would fire spontaneously.D. all of the above.E. none of the above.
10. If a motor neuron in the body were stimulated by an electrode placed aboutmidpoint along the length of the axon:
D. the membrane would become hyper polarized.E. nothing would happen.
