Neuroanatomy Exam 2 Questions And Accurate Answers
E Aphasia is a complex symptom, and though it does exist with nucleus ambiguus
dysfunction, it also exists with the dysfunction of other neural structures, including the
hypoglossal nucleus/nerve and regions of the cortex; this make it an inappropriate test -
ANSWER Which of the following is NOT a test or sign for the proper function of the
nucleus ambiguus?
A. Palate elevation
B. Uvula deviation
C. Vocal cord function
D. Gag reflex
E. Aphasia
E, C (the interneuron of this reflex projects bilaterally, meaning a blink should be elicited
in both eyes - unilateral blink reflex is abnormal) - ANSWER The corneal blink reflex is a
bisynaptic pathway. Identify the location of both synapses in the order in which they
occur.
A. Facial sensory nucleus
B. Principal sensory nucleus
C. Facial motor nucleus
D. Trigeminal motor nucleus
E. Spinal trigeminal nucleus

D, A - ANSWER The interneuron for the gag reflex runs from the ___ to the ___.
,A. Nucleus ambiguus
B. Superior salivatory nucleus
C. Inferior salivatory nucleus
D. Solitary nucleus
E. Spinal trigeminal nucleus
