  1. The ________ division of the autonomic nervous system is said to function during "rest and digest."
    parasympathetic
  2. Preganglionic fibers leave the CNS and then synapse on
    ganglionic neurons
  3. Preganglionic neurons of the autonomic nervous system are located in
    both the brain and the lateral gray horns of the spinal cord
  4. The parasympathetic nervous system is especially active during which physiological state?
    digestion
  5. Sympathetic preganglionic neurons are ________ and have ________ axons.
    short; myelinated
  6. Sympathetic preganglionic neurons are ________ and have ________ axons.
    short; myelinated
  7. Clusters of ganglionic sympathetic neurons that innervate organs in the abdominopelvic region are called ________ ganglia.
    collateral
  8. Stimulation of the neurons in the celiac ganglion would lead to
    hydrolysis of liver glycogen reserves
  9. Sympathetic nerves
    are bundles of postganglionic fibers that innervate organs within the thoracic cavity
  10. The suprarenal medullae secrete
    both epinephrine and norepinephrine
  11. As the result of an accident, the white rami of spinal nerves T1 and T2 on the left side of Brad's body are severed. What organ(s) would you expect might be affected by this injury?
    left pupil and the heart
  12. Stimulation of α1 adrenergic receptors by norepinephrine results in
    release of calcium ions from intracellular stores
  13. A certain drug decreases heart rate by blocking a receptor on cardiac pacemaker cells. This drug probably binds to ________ receptors.
    beta-1 adrenergic
  14. Ganglionic neurons in the suprarenal gland
    release epinephrine into blood capillaries
  15. Intramural ganglia in the digestive, urinary, and reproductive organs are innervated by the ________ nerves.
    pelvic
  16. The statement "its postganglionic axons always use acetylcholine as the neurotransmitter" is
    true only for the parasympathetic nervous system
  17. Nicotinic receptors
    open chemically-gated sodium ion channels
  18. The statement "Preganglionic axon terminals release acetylcholine" is
    true for both the parasympathetic and sympathetic nervous systems
  19. Drugs that block nicotinic receptors would be
    autonomic blocking agents
  20. The statement "it controls the diameter of the pupil" is
    true for both the parasympathetic and sympathetic nervous systems
  21. A decrease in the autonomic tone of the smooth muscle in a blood vessel would result in
    an increase in blood flow through the vessel
  22. Visceral reflex not coordinated by the medulla oblongata?
    pupillary reflex
  23. Long-term memories that are with you for a lifetime are called
    tertiary memories
  24. Based on stimulation studies, the "headquarters" of the reticular activating system appears to be based in the
    midbrain.
  25. The brain waves produced by normal adults while resting with their eyes closed are ________ waves.
    alpha
