What are the advantages of the hormonal coordination over the nervous coordination?
Organisms with a central nervous system (CNS) are well adapted to cope with changes in the external environment and within the body. The nervous system has three distinct functions:
- Collection of information about changes in its environment, both internal and external.
- Processing this information and often relating it to previous experiences.
- Acting on this information by coordinating the response of the organism.
One remarkable feature is the speed of the response which is virtually instantaneous.
