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
