प्रश्न
How does the human nervous system work? Explain.
उत्तर
When the sense organs such as eyes, ears, nose, tongue or skin are affected in our body, they send message to the brain in the form of electrical impulses through the sensory neurons. The brain analyses this message and decides the action to be taken. The brain, then, sends out instructions to the muscles of the concerned body part through the motor neurons. The concerned body part, then, acts according to the instructions sent by the brain.
