1 By Mariah Costa, Kim Moss, Miles Christian, and Tatianna Clanton You get on my cranial nerves!

2   Olfactory Nerve- Controls the sensory of smell  Optic Nerve- Controls sensory for vision  Oculomotor Nerve- Motor to the muscles that move the eye.  Trochlear Nerve- Motor to superior oblique muscles of the eyeball.  Trigeminal Nerve- Motor for the muscles of mastication. Sensory from the face  Abducens Nerve- Motor to the lateral rectus muscle of the eyeball. Definition

3   Facial Nerve- Motor supplies the muscles of the face and scalp. Sensory controls the submandibular, sublingual, and lacrimal gland.  Vagus Nerve- Controls over the voluntary muscles of the pharynx, vocal cords, larynx, heart, lungs, digestive organs.  Vestibular Nerve- For the equilibrium and cochlear nerve for hearing.  Glossopharyngeal Nerve- Function to a small muscle of pharynx, tonsil, and posterior.  Spinal Accessory Nerve- Control over muscles of the pharynx palate, sterncleido mastoid, and trapezius muscles.  Hypoglossal Nerve- Supplies the muscles of the tongue, thyroid, cartilage, and hyoid bone. Definition (cont.)

4  Symptoms depend upon which nerve is damaged  Olfactory nerve (I) Loss of sense of smell Perversion of sense of smell  Optic Nerve (II) Blindness (partial or full) Displopia (double vision)  Oculomotor Nerve (III) Palsy of the eyes (paralysis and loss of feeling) Damage

5   Trochlear nerve (IV) Vertical displopia  Abducen nerve (V) Eye movement issues Lazy eye  Trigeminal nerve (VI) Corneal drying and pain Decreased salivation Numbness of nose, forehead or eyebrows Damage (cont.)

6   Facial nerve (VII) Paralysis of the face Oversensitivity to sounds Unusual or impaired sense of taste  Vestibulochochlear nerve (VIII) Vertigo Deafness and tinnitus (hear things that don’t exist)  Glossopharyngeal nerve Nasal regurgitation Damage (cont.)

7   Vagus nerve Weak voice Swallowing issues Choking and coughing  Spinal accessory nerve Inability to lift shoulders  Hypoglossal nerve More swallowing issues Speech problems Damage (cont.)

8   Glossopharyngeal Nerve Disease: Ninth cranial nerve orbits nuclei in the medulla. May be injured by diseases affecting the lower brain stem, floor of the posterior fossa, jugular foramen, nerves' external course.  The clinical manifestations(symptoms) include decreased salivation, and syncope ( episodes of loss of consciousness, can be triggered by coughing, sneezing, or anything that may cause the blood pressure to change, even a little)  Treatment- Mainly control the pain, anti-seizure medications may help.  Surgery may be used to take pressure off the glossopharyngeal. Disease

9   1. What does the first cranial nerve control a. Olfactory Nerve b. Optic Nerve c. Oculomotor d. Trochlear  2. What does the glossopharyngeal nerve effect? a. Movement within the eyes b. Ear Canal c. Eye Sight d. Facial Movement Questions
