Q. What are the two divisions of the autonomic nervous system?
The autonomic nervous system is divided into the parasympathetic nervous system and the sympathetic nervous system.
The sympathetic nervous system comprehends the nerves that come out from the ganglia of the neural chains lateral to the spinal column near the spinal cord and thus are distant from the tissues they innervate. The peripheral and central neurons associated to those neurons are also part of the sympathetic.
The parasympathetic nervous system is made of nerves and peripheral or central neurons related to the neural ganglia, visceral ganglia situated near the tissues they innervate.
