The central nervous system including brain and spinal cord.
The peripheral nervous system including nerves coming out from the brain and spinal cord, i.e., cranial nerves and spinal nerves.
In rabbit these membranes are piamater, arachnoid layer and duramater. The piamater is a thin highly vascularised membrane closely applied with the brain.
Parasympathetic nervous system is formed by the fibres of IIIrd , VIIth , IXth nerves and Xth cranial nerves and form from 2nd, 3rd and 4th sacral nerves. Ganglia of parasysmpathetic nerves lie in the head neck and sacral regions. They innervate all those organs which are innervated by the sympathetic nerves.
