Answer 1

12

Explanation:

Human beings have 12 pairs of cranial nerves that emerge directly from the brain and brainstem. They are designated by roman numerals (I to XII) and control essential sensory and motor functions of the head and neck, such as sight, smell, hearing, and facial movements. Only the vagus nerve (CN X) extends significantly beyond this region to reach internal organs in the thorax and abdomen.
