Cranial Nerve Exam: Normal

FOR THE COMPLETE NEUROLOGIC EXAM TUTORIAL PLEASE VISIT: https://neurologicexam.med.utah.edu/ The "NEUROLOGIC EXAM VIDEOS AND DESCRIPTIONS: AN ANATOMICAL APPROACH" uses over 250 video demonstrations with narrative descriptions in an online tutorial. It presents the anatomical foundations of the neurologic exam and provides examples of both normal and abnormal conditions as exhibited by patients.

(0:44) CN2 - Visual acuity The first step in assessing the optic nerve is testing visual acuity. (1:41) CN2 - Visual fields There are several different screening tests that can be used to assess visual fields at the bedside. (4:01) CN2 – Fundoscopy Direct visualization of the optic nerve head is an important and valuable part of assessing CN2. (4:48) CN2&3 - Pupillary Light Reflex Afferent or sensory limb of the pupillary light reflex is CN2 while the efferent or motor limb is the parasympathetics of CN3. (5:34) CN3,4&6 - Inspection & Ocular Alignment Before checking ocular movements it is important to inspect the eyes. (6:00) CN3,4&6 – Versions Testing extraocular range of motion with both eyes open and following the target is called versions. (6:22) CN3,4&6 – Ductions If misalignment of the eyes or diplopia on versions it is important to examine each eye with the other covered. (7:08) Supranuclear gaze systems – Introduction Supranuclear control of gaze ensures that the image that is being looked at is centered/maintained on the fovea of the retina. (7:26) Saccades Saccades are tested by holding up your two hands three feet apart and asking patient to look at the finger that is wiggling without moving their head. (7:50) Smooth Pursuit Ask to keep watching the target without moving their head. Then move the target slowly from side to side and up and down. (8:13) Optokinetic Nystagmus Optokinetic Nystagmus is a test of smooth pursuit with quick resetting saccades. (8:48) Vestibulo-ocular reflex Vestibulo-ocular reflex is obtained by having patient visually fixate on an object straight ahead, then rapidly turning head form side to side and up and down. (9:20) Vergence Vergence eye movements occur when the eyes move simultaneously inward or outward in order to maintain the image on the fovea that is close up or far away. (9:59) CN5 – Sensory Test for both light touch and pain in the 3 sensory divisions (forehead, cheek, and jaw) of CN5. (10:51) CN5&7 - Corneal reflex Ophthalmic division of CN5 is the sensory limb and a branch of CN7 to the orbicularis oculi muscle is the motor limb of the corneal reflex. (11:39) CN5 – Motor Motor division of CN5 supplies the muscles of mastication. (12:14) CN7 – Motor Motor division of CN7 supplies the muscles of facial expression. (12:57) CN7 - Sensory, Taste Taste is the sensory modality tested for the sensory division of CN7. (13:55) CN8 - Auditory Acuity, Weber & Rinne Tests Vochlear division of CN8 is tested by screening for auditory acuity. (15:05) CN8 – Vestibular Vestibular division of CN8 can be tested for by using the vestibulo-ocular reflex. (15:23) CN9&10 – Motor Motor division of CN9 & 10 is tested by having patient say "ah" or "kah". (15:56) CN9&10 - Sensory and Motor: Gag Reflex Gag reflex tests both the sensory and motor components of CN9&10. (16:09) CN11 – Motor CN11 is tested by asking patient to shrug their shoulders and turn their head against resistance. (16:49) CN12 – Motor CN12 is tested by having patient stick out their tongue and move it side to side.
