Q

Three ways the sympathetic chain can go

A
  1. Synapse at the same level as paravertebral ganglia
  2. down level, then synapse at the lower level
  3. level up, synapse at upper level, or bypass and synapse at prevertebral ganglion

Q

6 general functions of the autonomic nervous system

A
  1. to preserve homeostasis, provoke rxns to to protect the individual
  2. Afferent impulses from the viscera elicit reflex responses (generally cannot be controlled voluntarily)
  3. Many fibers of the ANS are active maintaining a basal tone in most organs (ex: constriction of blood vessels)
  4. sympathetic and parasympathetic nervous systems are generally antagonistic with exceptions (salivary glands)
  5. Activation of sympathetic system is generally associated with defense mechanism (expenditure of energy, glycogenolysis, inc muscle tone)
  6. Activation of parasympathetic system is associated with conservative/restorative - decrease in BP and body temp.
