2. Which of the following statements about pathways and functional significance of the vago-vagal reflexes in the gut is false?

  • sensory fibers for these reflexes run in the vagus and spinal nerves
  • vagal preganglionic neurons activate enteric neurons via acethylcholine
  • they include receptive relaxation, reflux and vomiting
  • motor fibers for these reflexes run exclusively in the vagus nerve

3. The sympathetic pathways:

  • originate in the cervical segment of the spinal cord
  • originate in the thoracic-lumbar segment of the spinal cord
  • originate in the sacral segment of the spinal cord
  • originate in the brain stem

4. Sympathetic efferent nerves to the gut predominantly:

  • inhibit myenteric neurons
  • excite neurons in the Enteric Nervous System
  • excite non-sphincter muscles during ‘flight or fight response’
  • inhibit major gut sphincters

5. The part of the motor system that acts in real time as motor error detector is:

  • Brodmann’s area 6
  • the basal ganglia
  • the cerebellum
  • the brainstem
