Comparison between Nervous system vs Endocrine system

Nervous system vs Endocrine system

Feature	Nervous system	Endocrine system
Type of control	Electrical impulse through neurons.	Chemical response through hormones.
Speed of response	Very fast	Slower
Duration of response	Short lived	Long lasting
Mode of transmission	Through nerves	Through blood stream
Target area	Specific and localized(like muscle)	Widespread cab target multiple organ.
Nature of response	Quick and immediate	Gradual and sustained
Example	Reflex action, movement.	Growth, sugar regulation, metabolism
Main organ involved	Brain, spinal cord, nerves	Endocrine glands, ex:- pituitary gland.

Why both system are needed:- 

1. Different speeds:- 

• The nervous system gives Quick instant response. Ex: Reflex 
• The Endocrine system gives slow but Long lasting response. Ex: Growth

2. Different functions :- 

• Nervous system controls movement, reflex, and senses.
• Endocrine system controls metabolism, growth, Reproduction and mood 

3. Balance and coordination:- 

• Together the keep body in Balance [homeostasis]
• Ex: Brain (nervous) tells adrenal gland (endocrine) to release Adrenaline in stress.

4. Short term and long term:- 

• Nervous system handles emergency and short term actions
• Endocrine manages long term process like growth and development.

5. Support each other:- 

• Some organs like hypothalamus link both systems and helps the to work together for better control.
