Hank takes you on a tour of your two-part autonomic nervous system. This episode explains how your sympathetic nervous system and parasympathetic nervous system work together as foils, balancing each other out. Their key anatomical differences - where nerve fibers originate and where their ganglia are located - drive their distinct anatomical functions, making your sympathetic nervous system the fight or flight while your parasympathetic nervous system is for resting and digesting. • Pssst... we made flashcards to help you review the content in this episode!
