Lab Exam Study Guide – Nervous System and Special Senses Anatomy & Physiology – Instructor: Fred Wendler Name: ____________________________________ Label the twelve cranial nerves on the picture below. The picture is shifted to the right of the page so that you can label the cranial nerves on one side. Although the cranial nerves are paired on the left and right sides of the body, you only need to label the one side. You can write the names of the cranial nerves or the cranial nerve numbers.

Lab Exam Study Guide – Nervous System and Special Senses Anatomy & Physiology – Instructor: Fred Wendler Name: ____________________________________ Following are questions from the Cranial Nerve Testing Lab. For each question, write the correct cranial nerve

for each question.

You ask a subject to focus on the far side of the room for 1 minute. You then direct the subject to switch his/her focus to an object in your hand (e.g. a pencil). You then watch the subject’s pupils carefully as the point of focus is changed from far to near. You are testing what cranial nerve(s)? You ask a subject to protrude his/her tongue. You check for abnormal deviation or movement (e.g. does the tongue move straight forward or does it move to one side?). You are testing what cranial nerve(s)? You test a subject’s vision by having him/her stand 20 feet from a Snellen chart and read the chart, starting at the largest line and progressing to the smallest line he/she is able to see clearly. You record the ratio next to the smallest line the subject can read without mistakes (20/20, 20/30), etc.) You are testing what cranial nerve(s)? Assess the subject’s hearing by rubbing thumb and forefinger together close to the subject’s ear. You are testing what cranial nerve(s)? You hold an unknown sample under the subject’s nose and have him/her identify the substance by its scent. You are testing what cranial nerve(s)? Have the subject stand with their eyes closed and arms at their sides for several seconds. Evaluate their ability to remain balanced. You are testing what cranial nerve(s)? Have the subject perform the following actions individually: smile, frown, raise the eyebrows, puff the cheeks, open and close the jaw, clench the teeth, raise the shoulders. You are testing what cranial nerve(s)? Draw a large, imaginary “Z” in the air with your finger. Have the subject follow your finger with their eyes without moving their head. Repeat the procedure, this time drawing the letter “H” with your finger. You are testing what cranial nerve(s)?
