Why is the brain referred to as the powerhouse of the human being?

The brain is often referred to as the powerhouse of the human being because it is responsible for controlling and coordinating all of the body's functions. It is the center of the nervous system and is involved in everything from thinking and reasoning to controlling movement and regulating bodily functions such as breathing and heart rate. The brain is also responsible for processing sensory information, storing memories, and controlling emotions. In essence, the brain is the control center of the body, making it essential for overall human functioning and survival.

The brain is not referred to as the powerhouse of the human being. The mitochondria are often referred to as the powerhouse of the cell because they are responsible for producing the cell's energy.
