Stimulation of several brain areas has been shown to induce similar changes in liver glucose metabolism as produced by direct stimulation of sympathetic or parasympathetic nerves. These brain areas are either proposed or proven to be able to affect liver glucose metabolism via their effect on autonomic neuronal output.

How does stress affect the parasympathetic nervous system?

When you are stressed, this system triggers these necessary responses, and the function of your rest and digest system is reduced.

The autonomic nervous system has three branches: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

Does parasympathetic dilate blood vessels?
