Many children and some adults do not develop any symptoms until complications, such as cirrhosis develop.

The autonomic nervous system (ANS) is a very complex, multifaceted neural network that maintains internal physiologic homeostasis. This network includes cardiovascular, thermoregulatory, GI, genitourinary (GU), and ophthalmologic (pupillary) systems (see the following image).
The autonomic nervous system (ANS) is a system of motor neurons that innervate smooth muscle, cardiac muscle and glands. The autonomic nervous system has two divisions: Sympathetic and Parasympathetic.They mostly innervate the same structures but cause opposite effects. The sympathetic division mobilizes the body during extreme situations such as exercise, excitement and emergencies.he âdorsal root gangliaâ is in the sensory somatic part of the peripheral nervous system and are sensory ganglia made up of cell bodies of sensory neurons.
