LECTURE OUTLINE CHAPTER 14 Marieb The Peripheral Nervous System: The Cranial Nerves and Spinal Nerves Lecture Outline Receptors: IX.. Cranial nerves – 12 pairs arise from brainstem Mnemonic – Out On Our Table Top Are Fruits, Very Green Veggies And Hamburgers. A. I Olfactory sensory smell ( by way of cribiform plate of ethmoid) B. II Optic sensory vision ( by way of optic foramen) C. III Oculomotor motor runs eye muscles ( by way of superior orbital fissure) D. IV Trochlear motor runs superior oblique eye muscle (by way of superior orbital fissure) E. V Trigeminal mixed, three major branches: 1. ophthalmic 2. Maxillary 3. Mandibular ( by way of 1. superior orbital fissure, 2. foramen rotundum, 3. foramen ovale) F. VI Abducens motor, runs lateral rectus eye muscle ( by way of superior orbital fissure) G. VII Facial mixed sensory & facial expression (by way of internal acoustic canal to stylomastoid foramen) H. VIII Vestibulocochlear sensory hearing and balance (by way of internal acoustic foramen) I. IX Glossopharyngeal mixed sensory & swallowing (by way of jugular foramen) J. X Vagus mixed, very important in ANS ( by way of jugular foramen) K. XI Accessory motor, swallowing, trapezius, &scm (by way of jugular foramen) L. XII Hypoglossal motor, tongue musculature (by way of hypoglossal canal) 1
