Cranial Nerves

**Cranial nerves** transmit specific sensory information from the head and neck directly to the brain. For sensations below the neck, the right side of the body is connected to the brain's left hemisphere and the left side of the body to the brain's right hemisphere. Whereas spinal information is processed contralaterally. Cranial nerve systems are predominantly ipsilateral. This means that a cranial nerve on the right side of the head is connected to the right side of the brain. Some cranial nerves, such as the olfactory, optic and vestibulocochlear nerves, contain only sensory axons. Others, including the trigeminal, facial, glossopharyngeal and vagus nerves, carry both sensory and motor axons; however, the vagus nerve is not part of the somatic nervous system. The trigeminal system transmits general somatosensory information from the face. *LICENSES AND ATTRIBUTIONS CC licensed content, Shared previously,14.1 Sensory Perception, Authored by: OpenStax College.
