Answer» 1. If all actions of the human body are controlled by brain, our body will get harm in dangerous situations. 2. Some actions may be delayed and our brain could not conduct reflex actions, which require immediate action to a stimulus. 3. For example, when we touch a hot object, we require an immediate response to save our hand. If the brain controls this action, the time taken will be more and our hand will burn. 4. So, it is controlled by spinal cord, the response will be quick, and we may escape the danger. 5. Nerves can not reach the every corner of the body, whereas hormones of endocrine glands can do that. 6. So it’s not good that all functions are controlled by brain.
