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.”
