E4-D5-12 Generally, the following Cranial Nerves have Somatic Motor Function or ANS Parasympathetic Motor Function (table 15.7 on text page 472) Cranial Nerve Somatic motor function ANS-Parasympathetic Motor function I olfactory II optic III oculomotor 4 extrinsic eye muscles Sphincter pupillae muscle in eye to make pupil constrict, and ciliary muscles to make lens rounded - thick IV trochlear V trigeminal VI abducens Superior oblique eye muscle Muscles of mastication Lateral rectus eye muscle Muscles of facial expression Increase secretion from lacrimal gland of eye VIII vestibulocochlear IX glossopharyngeal One Pharyngeal muscle Increase salivary gland X vagus Mos pharyngeal muscles Smooth muscles, heart glands XI accessory Trapezius muscle, sternocleidomastoid muscle Intrinsic and extrinsic tongue muscle VII facial XII hypoglossal 1. What are the Cranial Nerve Names for this chart? 2. What are the Somatic Motor functions for every CN except I, II & VIII? 3. What are the Parasympathetic Motor Functions for III, VII, IX, and X? 4. Why doesn’t CN I, II and VIII have a field to fill? They are primary sensory 5. Why isn’t the Sympathetic System part of the Chart? Sympathetic ANS is not a primary function of the Cranial Nerves
