  5. Nucleus Ambiguus contains the cell bodies of the
  1. a the timing of the tongue base retraction to contact the anteriorly and medially moving pharyngeal walls occurs later in the swallow
  2. b motor neurons of CNs IX and X
  3. c the sensory awareness of food
  4. d an interneuronal network of dorsal and ventral reticular bodies (in medulla) that comprise the central pattern generator
  5. e the greatest systematic changes in the oropharyngeal swallow

5 Multiple choice questions

  1. receptor fields on the posterior tongue (CN IX), fauces, tonsils, velum (CN IX), mucosa of the valleculae and pyriform recesses (CN X) and the salivary glands (CN VII) are stimulated by the presence of the bolus
  2. produce sequential swallow phases (oral followed by pharyngeal followed by esophageal)
  3. directed to various cranial nerve nuclei to translate the bursts into messages sent to muscles for specific action or contraction pattern
  4. CN V, CN VII, CN IX, CN X
  5. pass most easily through narrow sites in transit

5 True/False questions

  1. Swallowing is different from a simple reflex in that it can not be elicited by isolated nerve activation, ratherinvoluntary, stereotyped and identical in different people


  2. The bilateral anterolateral regoins of the premotor cortex aredorsal regions (NTS) in the medulla to complete the swallow


  3. Thin liquids aredeformed more easily and move more readily in response to gravity and compression


  4. Information about the motor movement comes from theon thicker food


  5. The "swallowing cortex" is a discrete area located intime-ordered organization of movements, especially the sequential performance of multiple and voluntary movements
