The center viewing screen shows a rotating brain. Touch the brain and rotate as you like, able to enlarge the view as well. At the top is a sub-category displaying other brain images. Select one or continue on by selecting your data, On the right side bar, scroll through and select CERVICAL NERVES. That specific image displays along with a text/data box.
