carries impulses for the sense of smell

carries impulses for vision

supplies motor fibers four of the six muscles that direct the eyeball, to the eyelid

supplies motor fibers for one external eye muscle

conducts sensory impulses from the skin of the face and mucosa of the nose and mouth

supplies motor fibers to the lateral rectus muscle, which rolls the eye laterally

activates muscles of facial expression and the lacrimal and salivary glands

vestibular branch transmits impulses for the sense of balance. cochlear branch transmits impulses for the sense of hearing

supplies motor fibers to the pharynx (throat) that promote swallowing and saliva production

fibers carry sensory impulses to the pharynx, larynx, and the abdominal and thoracic viscera

mostly motor fibers that activate the sternocleidomastoid and trapezius muscles

motor fibers control tongue movements

acts to support neurons

help control the chemical environment in the brain by picking up excess ions and recapturing released neurotransmitters. Forms a living barrier between capillaries and neurons

spider like phagocytes that dispose of debris, including dead brain cells and bacteria

help circulate the cerbrospinal fluid that fills those cavities and forms a protective cushion around the CNS

wrap around nerve fibers, which produces fatty insulating coverings and myelin sheath

transmit impulses form PNS to CNS

transmit impulses from CNS to muscles or glands

located within CNS and conducts impulses between sensory and motor neurons
