    Neuron cell bodies

  • 13

    Dura Mater

    Trigeminal Nerve (CN V)

  • 14

    Fallopian Canal

    Facial Nerve (CN VII)

  • 15

    Inferior to Jugular Foramen

    Glossopharyngeal Nerve (CN IX)

  • 16

    inferior to Jugular Foramen

    Vagus Nerve (CN X)

  • 17

    Most motor neuron cell bodies in _______ of Brain Stem

    Ventral Gray Matter

  • 18

    Pass through Cribriform Plate of Ethmoid Bone

    Olfactory Nerves

  • 19

    ______ continue to Thalamus, where they synapse

    Optic Tracts

  • 20

    Fibers extend from Ventral Midbrain through Superior Orbital Fissures to four of six extrinsic eye muscles

    Oculomotor Nerves

  • 21

    Fibers from dorsal midbrain enter orbits via superior orbital fissures to innervate Superior Oblique Muscle –Primarily motor nerve that directs eyeball

    Trochlear Nerves

  • 22

    –Largest cranial nerves; fibers extend from Pons to face –Three divisions ●Ophthalmic (V1) passes through Superior Orbital Fissure ●Maxillary (V2) passes through Foramen Rotundum ●Mandibular (V3) passes through the Foramen Ovale

    Trigeminal Nerves

  • 23

    (Trigeminal Nerves) Convey sensory impulses from various areas of face

    V1 & V2

  • 24

    Supply motor fibers for mastication

    V3

  • 25

    Fibers from inferior Pons enter orbits via Superior Orbital Fissures –Primarily a motor, innervating Lateral Rectus Muscle

    Abducens Nerves

  • 26

    Fibers from Pons travel through Internal Acoustic Meatuses & emerge through Stylomastoid Foramina to lateral aspect of face –Chief motor nerves of face with five major branches –Sensory function (taste) from anterior two-thirds of tongue

    Facial Nerves

  • 27

    Afferent fibers from hearing receptors (cochlear division) & equilibrium receptors (vestibular division) pass from inner ear through internal acoustic meatuses & enter brain stem at pons-medulla border –Mostly sensory function; small motor component for adjustment of sensitivity of receptors

    Vestibulocochlear Nerves (formerly Auditory Nerves)

  • 28

    Fibers from medulla leave skull via jugular foramen & run to throat –Motor functions: innervate part of tongue & pharynx for swallowing & provide parasympathetic fibers to parotid salivary glands Posterior tongue

    Glossopharyngeal Nerves

  • 29

    Only Cranial Nerves that extend beyond head & neck region –Fibers from Medulla exit skull via Jugular Foramen –Most motor fibers are Parasympathetic fibers that help regulate activities of heart, lungs, & abdominal viscera, posterior tongue & pharynxlungs

    Vagus Nerves

  • 30

    Formed from Ventral Rootlets from C1 to C5 region of Spinal Cord (not brain) –Rootlets pass into cranium via each foramen magnum –Accessory nerves exit skull via jugular foramina to innervate trapezius & sternocleidomastoid muscles

    Accessory Nerves (Formerly Spinal Accessory Nerve)

  • 31

    Fibers from Medulla exit skull via Hypoglossal Canal –Innervate extrinsic & intrinsic muscles of tongue that contribute to swallowing & speech

    Hypoglossal Nerves
