Navigating the Peripheral Nervous System Purpose: This assignment is designed to help you explore, practice and understand the anatomy of the peripheral nervous system (PNS), become fluent with terminology, and identify areas requiring further study. This is an important step toward being able to apply your knowledge of neuro- anatomy to actual clinical cases in your professional careers. This activity is worth 2 points. When you are finished, I hope you will have a better understanding of: • The vocabulary...
