Can You Differentiate Sympathetic And Parasympathetic Nervous System?

Differentiate Sympathetic And Parasympathetic

Characteristics
  
  difference of
  Parasympathetic  NS
and
  Sympathetic  NS respectively,
  

• Origin
  

  Craniosacral   outflow
  &
  Thoracolumnar outflow [respectively]
  

• Location of ganglia
  

  Ganglia in (intramural= terminal) or close to visceral
  organ served
  &
  Ganglia within a few cm of CNS: Alongside vertebral column
  (paravertebral ganglia=chain) and anterior to vertebral column.

• Relative length of pre- and postganglionic fibers

          -long pre ganglionic  short postganglionic
           &
          -short pre ganglionic  long postganglionic

• division

          resting and digesting
          &
          fight or flight

• Blood vessel innervation  
  

          only by sympathetic division

• terminal nerve endings secrete

           acetylcholine
           &
           norepinephrine

• postganglionic neurons

          cholinergic
          &
          adrenergic

• neurotransmitter

          acetylcholine
          &
           norepinephrine      

• principal type of receptors

          acetylcholine receptors[muscarinic & nicotinic]
          &
          adrenergic receptors[alpha & beta]

• effects on different organs e.g,eye

         parasympathetic causes constriction of pupil
         &
         sympathetic causes dilatation of pupil.
