Question

Quizplus · Accepted Answer

Cranial nerves III, VII, IX, and X have autonomic components.

These nerves are responsible for controlling various involuntary functions, such as regulating heart rate, digestion, and breathing. For example, the parasympathetic fibers of the oculomotor nerve (III) control the constriction of the pupil, while the parasympathetic fibers of the glossopharyngeal nerve (IX) and the vagus nerve (X) control salivation and gastrointestinal function. The facial nerve (VII) also contains parasympathetic fibers that control lacrimation and salivation.
