Question
Differentiate: Nervous control and Hormonal control.

Answer

Nervous ControlHormonal Control
The information is sent in the form of electric signals.The information is sent in the form of chemical signals.
The signals travel through nerve fibres to specific target cells like muscle fibres and glands.The signals travel through blood stream to cells in different organs.
Nervous system causes muscles to contract or relax, glands to secrete more or less. But it cannot bring about growth.Endocrine system brings about changes in metabolic activities of all body tissues. It affects growth.
Action is immediate (within few milliseconds.)Action is slow (can take hours or days to produce response).
Effect lasts for a sliort time.Effect is more lasting and permanent.
