Examination of the Cranial Nerves When testing the cranial nerves one must be cognizant of asymmetry. The following is a summary of the cranial nerves and their respective functioning. I - Smell II - Visual acuity, visual fields and ocular fundi II,III - Pupillary reactions III,IV,VI - Extra-ocular movements, including opening of the eyes

When an attempt is made to gaze contralaterally (relative to the affected eye), the affected eye adducts minimally, if at all. The contralateral eye abducts, however with nystagmus. CRANIAL NERVES. Olfaction (CN I) Ophthalmoscopic Exam (CN II) Vision (CN II) Pupillary Responses (CN II, III) Extraocular Movements (CN III, IV, VI) Facial Sensation and Muscles of Mastication (CN V) Muscles of Facial Expression and Taste (CN VII) Hearing and Vestibular Sense (CN … 2017-02-05 Cranial Nerve III, IV and VI . Testing Procedures - Divergence. Facing the patient, hold an object such as a pencil about 1 inch away from the patient's nose. Instruct the patient to focus on the object and then slowly move the object away from the patient at a steady rate; the patient should demonstrate symmetrical divergence (pictured below).

Together, these muscles and nerves regulate the movement of the eyes in the six cardinal directions Cranial Nerves I,II,III,IV & VI : Cranial Nerves I,II,III,IV & VI Arjun Raj. Fact : Fact The olfactory and optic nerves are not true peripheral nerves but extensions (tracts) of the telencephalon and diencephalon, respectively. They are therefore not associated with cranial nerve nuclei in the brainstem. Temporary paralysis of cranial nerves III, IV, and VI after a Gow-Gates injection. Fish LR(1), McIntire DN, Johnson L.
