The only cranial nerve that enters and leaves the skull through different foramina is the cranial nerve XI (the accessory nerve). It enters the skull through the foramen magnum along with the spinal cord and exits through the jugular foramen, which is located between the temporal bone and occipital bone. The other cranial nerves all enter and exit the skull through the same foramen.
