Any of the following cranial nerves has the parasympathetic nucleus EXCEPT:

  • A. vagal
  • B. oculomotor
  • C. glossopharyngeal
  • D. olfactory
Correct Answer: D

Rationale: Olfactory nerve is the correct answer because it is a sensory nerve responsible for the sense of smell and does not have a parasympathetic nucleus. In contrast, the vagus, oculomotor, and glossopharyngeal nerves all have parasympathetic components that regulate functions such as heart rate, pupil constriction, and salivation.
