Question

What is/are the advantage(s) of the endocrine system over the nervous system?

• A. Higher reach of chemical messengers over nerve signalling.
• B. Sustained stimulation by chemical messengers.
• C. Ensures messages for continuous processes like growth.
• D. Conveys information quickly.

Answer 1

Answer: (A), (B), (C)

The correct options are
A Higher reach of chemical messengers over nerve signalling.
B Sustained stimulation by chemical messengers.
C Ensures messages for continuous processes like growth.

Chemical coordination allows coverage of larger areas of the body as the messengers are present in blood. Hormones in chemical coordination allow sustained stimulation unlike the nerve impulses which are quick but short-lived. For processes which need information for a longer duration are regulated by hormones as they generate gradual response and can work for a long time.
