Nervous system controls

I get asked a lot what the nervous system controls so here ya go:

The autonomic nervous system (ANS), also known as the visceral nervous system and involuntary nervous system, is a division of the peripheral nervous system that influences the function of internal organs.[1] The autonomic nervous system is a control system that acts largely unconsciously and regulates the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal. This system is the primary mechanism in control of the fight-or-flight response and its role is mediated by two different components.

All of this is supposed to be involuntary but mine does what it wants and when it wants so all of my symptoms involve one or more of the above. So, any of them could get thrown off at any point and go crazy, leaving me stuck in bed. It controls a lot more than people think and that is why my symptoms aren't consistent.
