The nervous system carries out the following functions:

-
It controls and coordinates all the activities of the muscles in response to
the changes outside
- It also maintains the internal environment of
the body by coordinating the functions of the various internal organs and
the involuntary muscles
- It stores the previous experiences as memory that helps us to think and analyse
our reactions

body
