Final take home message: Make sure to still read the Powerpoint slides and know the information well. Look over the quiz questions and homework questions.

(Know the cranial nerves and their numbers. Know which spinal nerves belong to which plexus)

As far as labeling, if you can label it in this powerpoint, you will be fine for the exam.

*AS A REMINDER – THE EYE AND EAR IS NOT ON THIS REVIEW. BUT IT WILL BE TESTED. PLEASE REVIEW THE SLIDES ON LECTURE 21 & 22**
