  • *Fungsi saraf kranial

  • CN I: Olfactory NervesSensory nerves of smell

  • CN II: Optic NerveSensory nerve of vision

  • CN III: Oculomotor NerveInnervates four of the extrinsic eye muscles

  • CN IV: Trochlear NerveInnervates an extrinsic eye muscle

  • CN V: Trigeminal NerveProvides sensory innervation to the faceMotor innervation to chewing muscles

  • CN VI: Abducens NerveAbducts the eyeball

  • CN VII: Facial NerveInnervates muscles of facial expressionSensory innervation of faceTaste

  • CN VIII: Vestibulocochlear NerveSensory nerve of hearing and balance

  • CN IX: Glossopharyngeal NerveSensory and motor innervation of structures of the tongue and pharynxTaste

  • CN X: Vagus NerveA mixed sensory and motor nerve Main parasympathetic nerveWanders into thorax and abdomen

  • CN XI: Accessory NerveAn accessory part of the vagus nerveSomatic motor function of pharynx, larynx, neck muscles

  • CN XII: Hypoglossal NerveRuns inferior to the tongueInnervates the tongue muscles

  • Disorders of the PNS: ShinglesShingles (herpes zoster) Viral infectionStems from childhood chicken poxOften brought on by stressMostly experienced by those over 50

  • Disorders of the PNS: Migraine HeadacheMigraine headacheRelates to sensory innervation of cerebral arteriesArteries dilateCompresses and irritates sensory nerve endings

  • Disorders of the PNS: Myasthenia GravisMyasthenia gravis Progressive weakening of the skeletal musclesAn autoimmune disorderAntibodies destroy acetylcholine receptors Ptosis due to weakness of eyelid muscles
