  2. Changes in bolus volume create
  3. Insular cortex, particularly the anterior isula is involved in
  4. CPG input functions
  5. Nucleus Tractus Solitarius is located in
  1. a the coordination of interaction of oral musculature, gustation, and autonomic functions
  2. b 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
  3. c the greatest systematic changes in the oropharyngeal swallow
  4. d ventral medulla
  5. e the dorsal medulla in the brainstem

5 Multiple choice questions

  1. the timing of the tongue base retraction to contact the anteriorly and medially moving pharyngeal walls occurs later in the swallow
  2. on thicker food
  3. pass most easily through narrow sites in transit
  4. produce simultaneous oral and pharyngeal phase activity in order to safely clear the large bolus from both the oral cavity and the pharynx
  5. believed to coordinate the sequence of tongue and facial movements

5 True/False questions

  1. In addition to receiving info from CNs VII, IX, X it also receives input fromstructures involved in motor control including motor/pre-motor cortex via descending motor pathways


  2. Nucleus Ambiguus connects with the motor nuclei ofCNs V, VII, XII


  3. Thicker foods also heightenthe sensory awareness of food


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


  5. The more viscous the bolusthe less agility and control required, more forgiving when timin of swallow and coordination of transit are impaired
