CRANIAL NERVES Cranial nerves are ordered according to their location in the brainstem: Telencephalon I. olfactory smell II. optic vision Midbrain III. oculomotor eye movements IV. trochlear eye movements Pons V. trigeminal mastication, sensation from face, head, oral cavity VI. abducens eye movements VII. facial facial expression, taste anterior 2/3 tongue VIII. acoustic vestibular sense, audition Medulla IX. glossopharyngeal stylopharyngeus muscle -involved in swallowing, taste post. 1/3 X. vagus pharyngeal & laryngeal muscles(swallow,phonation), sensation XI. accessory neck muscles (trapezius, sternocleidomastoid) XII. hypoglossal tongue muscles (genioglossus, styloglossus, hypoglossus) Can also group by functional neuronal components: A. Only Sensory :olfactory smell optic vision vestibulocochlear: B. Only Motor : trochlear eyeball movement; (superior oblique muscle) abducens eyeball movement; (lateral rectus muscle) accessory neck muscles hypoglossal muscles of the tongue oculomotor: four eyeball muscles C. Mixed : trigeminal: sensory; face (surface of head and neck) motor; muscles of mastication facial: sensory - taste (anterior 2/3 of tongue) parasympathetic (glands of head) motor - facial expression glossopharyngeal: vagus: 1
