Question

What is difference between nervous and chemical(endocrine) system???

Answer 1

Answer:

Endocrine system uses chemical signaling (hormones produced by glands) while the nervous system uses electrical signaling (neural impulses).

Answer 2

Answer:

The differences are given below ↓

Nervous System

• Electrical impulses are the messengers in the nervous system
• Brain and the spinal cord constitute the nervous system
• Nerve impulses are transmitted through neurons
• The nervous system is under both voluntary and involuntary control
• Nerve impulses make use of the neurotransmitters at synaptic clefts and sodium and potassium channels and enter the target cells
• Responses are localised

Chemical (Endocrine) System

• Hormones are the chemical messengers in the endocrine system that target cells through the bloodstream
• Glands and organs like thyroid, pituitary glands and reproductive organs (ovaries and testes) are involved in the endocrine system
• Hormones are transmitted through blood vessels
• The endocrine system is under involuntary control
• The hormones enter into the target cells by diffusing through the plasma membrane or by binding to the cell receptors
• Responses are widespread
