Which of the following cranial nerves is not involved in the parasympathetic nervous system?
A
Hypoglossal nerve (CN XII)
B
Facial nerve (CN VII)
C
Oculomotor nerve (CN III)
D
Vagus nerve (CN X)
Verified step by step guidance1
Begin by understanding the role of the parasympathetic nervous system, which is part of the autonomic nervous system responsible for 'rest and digest' functions.
Identify the cranial nerves that are involved in the parasympathetic nervous system. These typically include the oculomotor nerve (CN III), facial nerve (CN VII), glossopharyngeal nerve (CN IX), and vagus nerve (CN X).
Review the functions of each cranial nerve listed in the problem. The oculomotor nerve (CN III) is involved in pupil constriction, the facial nerve (CN VII) controls salivary glands, and the vagus nerve (CN X) affects heart rate and digestion.
Consider the hypoglossal nerve (CN XII), which primarily controls tongue movements and is not associated with parasympathetic functions.
Conclude that the hypoglossal nerve (CN XII) is the cranial nerve not involved in the parasympathetic nervous system, as it does not contribute to 'rest and digest' activities.
