Answer #1

Answers are:

(a) sympathetic preganglionic neurons:

  • Reside in spinal cord
  • Release acetylcholine

(b) sympathetic postganglionic neurons:

  • Release noradrenaline
  • Have nicotinic receptors (acetylcholine released from preganglionic fibres act on these receptors)

(c) parasympathetic preganglionic neurons:

  • Reside in brainstem
  • Release acetylcholine

(d) parasympathetic postganglionic neurons:

  • Release acetylcholine
  • Have nicotinic receptors

Note: neurotransmitters released from postganglionic fibres of sympathetic and parasympathetic neurons i.e noradrenaline and acetylcholine respectively,acts on receptors located in different locations of body.

Parasympathetic-nicotinic and muscarinic

Sympathetic-adrenergic
