5 Matching questions

  1. Parasympathetic innervation of the heart
  2. deep cardiac plexus
  3. cervical and third and fourth thoracic sympathetic ganglia
  4. Greater splanchnic nerve
  5. Nervous system subdivisions
  1. a vagus nerve
  2. b where upper 5-6 thoracic spinal segments' sympathetic pregangionic nerves synapse on postganglionic fibers. from here, postganglionic fibers go bilaterally to the heart
  3. c T5 to T9. pierces the crus of diaphragm and synapses at ganglia of celiac plexus, renal plexus and suprarenal medulla
  4. d between aortic arch and trachial bifurcation
  5. e CNS PNS

  4. Cranial Nerves and ganglia
    • Spinal nerves and ganglia
  5. in the cervical and third and fourth thoracic sympatehtic ganglia

5 True/False questions

  1. CNS includesbrain and spinal cord


  2. Dorsal root of spinal nervecontains somatic and visceral efferent fibers


  3. Splanchnic nervesformed by efferent preganglionic sympathetic neurons that do not synapse on postganglionic neurons until closer to the effector organ


  4. Effects of sympathetic stimulation of the heartfrom upper 5-6 segments of thoracic spinal cord lateral horn


  5. Least Splanchnic NerveT10 to T11. descends with greater splanchnic nerve synapses on post-ganglionic fibers in lower part of celiac ganglia
