Wihtin sensory it has pure sensory but also special sensory belonging to the taste. Charge of collecting taste of the 2/3 anterior of tongue Motor. Controles the muscles of the face gesture muscles Intermediate nerve VIII: orgin outside brain stem IX: MIXED special senosry it collects sensory bc. Taste, and facial nerve. Muscle of pharynx X: mixed nerve, only cranian nerve that carry signals between the brain, heart and digestive system. Collects sensory info XI: pure motor, to the neck region, big muscles XII: pure motor, controls muscles of our tounge
