The glossopharyngeal nerve is one of twelve cranial nerves that connect to the brain. Like the other cranial nerves, the glossopharyngeal nerve is paired — there's one on each side of your brain.

The cranial nerves start near the back of the brain and travel to muscles and organs in your head, neck, and trunk. They're responsible for many essential muscle movements and sensory experiences.

The vagus nerve is the longest of the 12 cranial nerves. Here, learn about its anatomy, functions, and the kinds of health problems that can occur.

The cranial nerves originate in the brain and travel outward to your head, face, and neck. The exception to this is the vagus nerve, which is the longest cranial nerve.
