As we have learnt:

 

Parasympathetic Neural System:

  • The preganglionic nerve fibres arise from Cranio sacral outflow (cranial nerves) 3, 7, 9, 10 and sacrum.
  • Preganglionic nerve fibres are longer than postganglionic nerve fibres.
  • Both pre and post ganglionic nerve fiber are cholinergic.
