Cranial Nerves Exam
[Purpose]
1048711 To learn how to examine the functions of the 12 pairs
of cranial nerves
1048711 To understand the functions of the 12 pairs of cranial
nerves
12 pairs of cranial nerves
Functions of cranial nerves
bull 1048711 Some of these nerves bring information from
bull the sense organs to the brain
bull 1048711 Others control muscles
bull 1048711 Others are connected to glands or internal
bull organs such as the heart and lungs
The innervation areas of the cranial nerves
[Experimental method amp procedure]
bull 1048711 CN I Olfactory smellbull 1048711 1 Ask the subject if heshe has a subjective olfactorybull problembull 1048711 2 Check for rash deformity of nosebull 1048711 3 One nostril is occluded while the subject sniffs anbull unknown substance Test one nostril with soap cigarettebull and toothpaste ask the subject to point to the correct namebull on the paperbull 1048711 4 Test the other nostril repeat step 3
CN II Optic vision
bull 1048711 There are three main aspects to this nerve visual
bull acuity visual fields and fundi opticus
bull 1048711 1 Examine visual acuity
bull 1048711 2 Examine visual fields
bull 1048711 3 Look into the fundi

bull 1048711 1 Appearance of eyes
bull 1048711 2 Eyeball movement
bull 1048711 3 Look at pupils
bull 1048711 4 Test pupillary light reaction

bull 1048711 Functionsbull 1048711 Chewingbull 1048711 Face amp mouth touch amp painbull 1048711 1 Facial sensationbull 1) Use sterile sharp item on forehead cheek and
jawbull 2) If abnormal then test temperature [water-
heatedcooledbull tuning fork] light touch [cotton]
bull 1048711 2 Motor Subject opens mouth clenches teeth
bull 1) Palpate temporal masseter muscles as they clench
bull 2) Subject opens mouth assess the symmetry of the
bull mouth
bull 1048711 3 Corneal reflex patient looks up and awaybull 1) Touch cotton wool to the sclera on the other sidebull 2) Look for blink in both eyes ask if subject can
sense itbull 3) Repeat on the other side
bull 1048711 4 Test jaw jerkbull 1) Examiner places finger on tip of jawbull 2) Grip patellar hammer halfway up shaft and tap
examinerrsquosbull finger lightlybull 3) Usually nothing happens or just a slight closure
CN VII Facial
bull 1048711 Functions controls most facial expressions
bull secretion of tears amp saliva taste
bull 1048711 1 Muscles of facial expression
bull 1048711 2 Check the sense of taste
CN VIII Vestibulocochlear
bull 1048711 Functions hearing equilibrium sensation
bull 1048711 Auditory acuity
bull 1048711 1 Rinne test
bull 1048711 2 Weber test

bull 1048711 Some useful tests for detection of deficiencies in motorbull function of the palate pharynx and larynx are described
belowbull Sensory function needs to be checked if one suspects
cranialbull neuropathy or a brain stem lesionbull 1 Palatal Elevationbull 2 Gag reflex (afferent IX efferent X)bull 3 Sensory functionbull 4 Voice Qualitybull 5 Taste test see CN VII

SternocleidomastoidTrapezius muscle
CN XI Accessory
bull 1048711 1 Sternocleidomastoidbull Press a hand against the patients jaw and have the patientbull rotate the head against resistance Pressing against the
rightbull jaw tests the left sternocleidomastoid and vice versabull 1048711 2 Trapeziusbull Have the patient shrug shoulders against resistance and
assessbull weakness
CN XII Hypoglossal
bull Function controls tongue movements
