  1. characteristic of the ANS, there are (1) cell bodies in the ___ that synapse with (2) autonomic _____, and finally with the (3) ____ (smooth muscle)
    CNS; ganglia; involuntary effector
  2. _______ motor neurons conduct along a single axon, unlike the ____ which involves two neurons (pre & postganglionic)
    somatic; ANS
  3. preganglionic neurons are in the ___, postganglionic neurons are in the ___
    CNS; PNS
  4. ________________ is compensation (more sensitive) by an effector organ to continue functioning even if ANS nerves are damaged
    denervation hypersensitivity
  5. Rest and digest: _____ ; Fight or Flight: _______
    parasympathetic nervous system ;sympathetic nervous system
  6. _____ occurs in Sympathetic chain ganglia as Preganglionic fibers branch to synapse with numerous postganglionic neurons
  7. ________ occurs when a postganglionic neuron receives input from a large number of preganglionic fibers.
  8. The ________ Nervous system preganglionic neurons only originate from between (thoracic)T1 down through (lumbar)L2 of the spinal cord.
  9. The _____ nervous system may have preganglionic neurons originate from the mid & hindbrain or the low (sacral) S2-4 of the spinal cord
  10. when shit gets real, the sympathetic nervous system's divergence and convergence of impulses causes __________
    mass activation
  11. The adrenal medulla works under mass activation to release adrenaline, which assists the ____ nervous system
  12. Sympathetic NS: efferent neurons exit the ___ root of the spinal cord
  13. the _______ nerve ("wandering nerve") provides parasympathetic innervation to the heart, liver, GI, lungs, etc.
  14. ___ is the NT of all preganglionic fibers (SNS & PSNS)
    Acetylcholine (cholinergic fibers)
  15. Most postganglionic nerve fibers release __________ NT
    norepinephrine (adrenergic fibers)
  16. _____ NS stimulates alpha and beta adrenergic receptors while the _______NS stimulates muscarinic receptors
    sympathetic; PSNS
  17. innervated by both SNS and PSNS is called ____________, which may be antagonistic, complementary, or cooperative
    dual innervation
  18. __________ dual innervation : each NS does a different job to enhance the same outcome (i.e. PSNS saliva secretion + SNS blood vessel constriction= more saliva)
  19. __________ dual innervation : each NS does a different job to allow something to work properly (i.e. PSNS arousal + SNS orgasm = sexual function)
  20. drugs like _____________ (belladonna) are muscarinic antagonists
  21. blushing, butterflies, and fainting are made possible by the _________ through the ANS
    limbic system
  22. arrector pili muscles in the skin, sweat glands in the skin, most blood vessels, and the _________________ are NOT dual innervated
    adrenal medulla
  23. Sympathetic nerves that pass through the sympathetic chain without synapsing and instead synapse later in _________ (i.e. Celiac & superior/inferior mesenteric ganglion)
    collateral ganglion (digestive, urinary, reproductive)
  24. Parasympathetic nerves that innervate within the effector organ or very close to it are called _____________
    terminal ganglia
  25. terminal ganglia are in the _____ NS
  26. collateral ganglia are in the _____ NS
  27. epinephrine is a _________
  28. norepinephrine is a __________
    hormone & NT
