How many cranial nerves originate from the brain?

Explanation:
Cranial nerves come from the brain, not the spinal cord, and there are twelve pairs in total. Two of them originate from the forebrain, handling functions like smell and vision, while the other ten arise from the brainstem and manage a mix of sensory and motor tasks in the head and neck. That’s why twelve is the correct count. Counts like eight, ten, or fourteen don’t match the actual number of distinct cranial nerves.
