What constitutes the central and peripheral nervous systems? How are the components of central nervous system protected?

Answers (1)

Solution:

The central nervous system consists of brain and the spinal cord. The peripheral nervous system consists of all the nerves in the body that lies outside of the spinal cord and brain.

The central nervous system has a well-developed system for its protection. Brain is enclosed in a hard shell know as skull. Spinal cord is enclosed in vertebral column for its protection. Along with these there is cerebrospinal fluid which protects the brain from mechanical shocks.
