Cranial Nerve Exam - Normal 22 - Cranial Nerves 9 & 10- Motor: The motor division of CN 9 & 10 is tested by having the patient say "ah" or "kah". The palate should rise symmetrically and there should be little nasal air escape. With unilateral weakness the uvula will deviate toward the normal side because that side of the palate is pulled up higher. With bilateral weakness neither side of the palate will elevate and there will be marked nasal air escape.
