  3. The Nucleus Ambiguus is located in the
  4. As bolus viscosity increases, adequate transit becomes
  5. In addition to receiving info from CNs VII, IX, X it also receives input from
  1. a more reliant on strength and constriction- the pressure generated by the oral tongue, tongue base, and pharyngeal walls increases and muscular activity increases
  2. b ventral medulla
  3. c involuntary, stereotyped and identical in different people
  4. d structures involved in motor control including motor/pre-motor cortex via descending motor pathways
  5. e time-ordered organization of movements, especially the sequential performance of multiple and voluntary movements

5 Multiple choice questions

  1. motor neurons of CNs IX and X
  2. more slowly in response to gravity and compression
  3. approximately 580 swallows per day
  4. the supplemental motor area, anterior to M1
  5. CN V, CN VII, CN IX, CN X

5 True/False questions

  1. If stimulus threshold is reached in NTS thensends information to the Nucleus Ambiguus to execute the specified motor sequence


  2. Information about the motor movement comes from themuscles spindles in the tongue via CN XII


  3. Changes in bolus volume createthe timing of the tongue base retraction to contact the anteriorly and medially moving pharyngeal walls occurs later in the swallow


  4. Thin liquids arepass most easily through narrow sites in transit


  5. The cortex has significant control overthe less agility and control required, more forgiving when timin of swallow and coordination of transit are impaired
