    • 2. Nicotine
    • 3. Muscarine
  2. The name given to describe how a autonomic pathway usually has one preganglionic neuron synapsed with on average 8 or 9 post ganglionic neurons. Making it possible to innervate more than one target cell.

    ACh
  6. Adenosine makes us tired and helps us fall asleep, caffeine blooks adenosine receptors. What is caffeine behaving as?
    Neuromodulator
  7. a substance, other than a neurotransmitter, released by a neuron and transmitting information to other neurons, altering their activities. A substance that alters nerve impulse transmission

  8. What NT does a postganglionic sympathetic nerve release?
    Norephinephrine
  9. A complex tissue within the right atrium containing pacemaker cells that normally determine the intrinsic firing rate for the entire heart
    SAN or Sinoatrial Node
