Question

What are the three differences between nervous control and chemical control in living organisms?

Answer 1

Nervous control :

• In this case, body of a living organism needs nervous tissues (nerve cells, neurons, neurotransmitters, etc.)
• It is a fast process and is less persistent (as neurons take time to reset)

• Reach to connected cells only.

Chemical control :

• In this case, body of a living organism needs endocrine glands ( hormones, enzymes, etc.)
• It is a slow process and is more persistent .
• Reach to all the somatic(body) cells.
