Peripheral Nervous System: Crash Course A&P #12

It is now time to meet the system that helps your crazy brain stay in touch with the outside world. We follow up last week's tour of the central nervous system with a look at your peripheral nervous system, its afferent and efferent divisions, how it processes information, the reflex arc, and what your brain has to say about pain. Pssst... we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!
