Which of the following correctly describes the order of events occurring during a sympathetic nervous system response?

Stimulation of cranial or sacral spinal regions; impulse reaches cranial root ganglion; acetylcholine release

Stimulation of cranial or sacral spinal regions; impulse reaches cranial root ganglion; norepinephrine release

Stimulation of thoracic or lumbar spinal regions; impulse reaches chain ganglion; acetylcholine release

Stimulation of thoracic or lumbar spinal regions; impulse reaches chain ganglion; norepinephrine release

Verified Answer :

Answer;

Stimulation of thoracic or lumbar spinal regions; impulse reaches chain ganglion; acetylcholine release

Explanation;

  • The sympathetic nervous system is part of the autonomic nervous system, which also includes the parasympathetic nervous system.
  • The sympathetic nervous system  functions by activating the fight or flight responses. It operates through a series of interconnected neurons.
  • Sympathetic neurons of the spinal cord communicate with the PNS via a series of sympathetic ganglia. Spinal cord sympathetic neurons joins with the peripheral sympathetic neurons through the chemical synapses.
  • At synapses, preganglionic sympathetic neurons release acetylcholine, which binds and activates nicotinic acetylcholine receptors on the postganglionic neurons.

Stimulation of thoracic or lumbar spinal regions; impulse reaches chain ganglion; acetylcholine release


The following information should be considered:

  • The sympathetic nervous system should be part of the autonomic nervous system, which also involved the parasympathetic nervous system.
  • The sympathetic nervous system functions by activating the fight or flight responses.
  • It operates through a series of interconnected neurons.
  • Sympathetic neurons of the spinal cord communicate with the PNS via a series of sympathetic ganglia.
  • Spinal cord sympathetic neurons joins with the peripheral sympathetic neurons via  the chemical synapses.
  • At synapses, preganglionic sympathetic neurons release acetylcholine, which binds and activates nicotinic acetylcholine receptors on the postganglionic neurons.
