Cranial nerves carry sensation from the face, head, and neck to the brain. They also carry information to and from the organs to the brain. They control the muscles in the face and throat. They let you see, hear, smell, and taste. And they connect the balance center of the inner ear to the brain.
The cranial nerves also control movement of the eyes and tongue and regulate certain body functions.
