You can easily fact check where do the nervous and endocrine systems communicate and why by examining the linked well-known sources.
The three organs that give electric eels the ability to generate electricity take up four fifths of its body. They can also control their victim's nervous system and muscles via electrical pulses, so they can keep prey from escaping or force it to move so they can locate its position
Because most of your body's cells are constantly replacing themselves at varying rate, only your central nervous system cells, your eye lens cells, and (for females) your eggs are as old as you are. The cells in other body parts are much younger: intestines - 3 days; lungs - 8 days; etc. - source

How does the nervous system work with other systems?
Box Jellyfish aren't jellyfish. True jellyfish can't see, don't have brains, and can't swim. Chironex fleckeri have 24 eyes, a complex nervous system, and can swim at 2 meters per second.
Snapping turtles hibernate underwater and can go for over 6 months without breathing. Their nervous system shuts down and their shells help neutralize toxins that build up in their bodies from anaerobic glycolysis.
Humans have about 100 million neurons, dubbed the 'second brain', embedded in the walls of the long tube of our gut, or alimentary canal, running from the esophagus to the anus. This enteric nervous system enables us to "feel" the inner world of our gut and its contents.
