Transcript

  • 1. CRANIAL NERVES III, V, VII, IX, X
  • 2. Parasympathetic Cranial Nerves Oculomotor (III) Facial (VII) Glossopharyngeal (IX) Vagus (X)
  • 3. Oculomotor Nerve Modalities: GSM: From: Oculomotor complex. To: 4 of 6 extrinsic muscles of the eye. Levator palpebrae superioris.
  • 4. Oculomotor Nerve Modalities: GVM: Preganglionics: From: Edinger-Westphal nucleus. To: Ciliary ganglion. Postganglionics: To: Sphincter pupillae.
  • 5. Trigeminal Nerve Three branches: Ophthalmic. Maxillary. Mandibular. Major sensory nerve to face. (Also supplies tongue, but this is general sensory, not special sensory for taste.) Motor to muscles of mastication: Muscles derived from first pharyngeal arch (mandibular arch).
  • 6. Trigeminal Nerve Not parasympathetic. Modalities: SVM: From: Masticator nucleus. To: Muscles of mastication. Tensor veli palatini. Tensor tympani. Mylohyoid. Anterior belly of digastric.
  • 7. Trigeminal Nerve Modalities: GSS: Cell bodies of sensory neurons in trigeminal (semilunar) ganglion. Sensory to: Face and anterior scalp. Conjunctiva and eyeball. Paranasal sinuses. Nasal and oral cavities. Anterior 2/3 of tongue. External surface of ear drum. Dura of middle and anterior cranial fossae.
  • 8. Facial Nerve Primary motor nerve to muscles of facial expression. Supplies muscles derived from second pharyngeal arch (hyoid arch). Branches: Temporal. Zygomatic. Buccal. Mandibular. Cervical.
  • 9. Facial Nerve Carries taste from anterior 2/3 of tongue. Carries motor to submandibular and sublingual salivary glands. Carries motor to lacrimal gland and mucous glands in nose.
  • 10. Facial Nerve Modalities: GVM: Preganglionics: From: Superior salivatory and lacrimal nuclei. To: Submandibular/sublingual ganglia.
  • 11. Facial Nerve Modalities: GVM: Postganglionics: To: Lacrimal gland. Submandibular gland. Sublingual gland. Mucous glands of mouth and nose.
  • 12. Facial Nerve Modalities: GSS: Cell bodies of sensory neurons in geniculate ganglion. Supplies sensory to part of external ear.
  • 13. Facial Nerve Modalities: SVS: Cell bodies of sensory neurons in geniculate ganglion. Carries taste from anterior 2/3 of tongue. Carries taste from hard and soft palates.
  • 14. Glossopharyngeal Nerve Motor to parotid gland. Carries taste from posterior 1/3 of tongue. Supplies general sensation to posterior 1/3 of tongue. Supplies muscles derived from third pharyngeal arch.
  • 15. Glossopharyngeal Nerve Modalities: SVM: From: Nucleus ambiguous. To: Stylopharyngeus.
  • 16. Glossopharyngeal Nerve Modalities: GVS: From: Carotid body. Carotid sinus.
  • 17. Glossopharyngeal Nerve Modalities: GVM: Preganglionics: From: Inferior salivatory nucleus. To: Otic ganglion. Postganglionics: To: Parotid gland.
  • 18. Glossopharyngeal Nerve Modalities: GSS: From: Posterior 1/3 of tongue. External ear. Middle ear cavity.
  • 19. Glossopharyngeal Nerve Modalities: SVS: From: Posterior 1/3 of tongue (taste).
  • 20. Vagus Nerve Motor to muscles of larynx: Muscles of fourth and fifth pharyngeal arches. Important in swallowing and speaking. Major parasympathetic nerve to thoracic and abdominal organs: Parasympathetic supply distally to left colic (splenic) flexure.
  • 21. Vagus Nerve Modalities: SVM: From: Nucleus ambiguous. To: Almost all muscles of pharynx and larynx.
  • 22. Vagus Nerve Modalities: GVS: From: Larynx and pharynx. Thoracic and abdominal viscera. GSS: From external ear and pharynx.
  • 23. Vagus Nerve Modalities: GVM: Preganglionics: From: Dorsal motor nucleus. To: Myenteric plexus of wall of gut tube.
  • 24. Vagus Nerve Modalities: GVM: Postganglionics: Smooth muscle of pharynx and larynx. Smooth muscle of most of wall of gut tube.
