What is brain.

The brain is the most important organ of the human body. It is the control center of the nervous system and is responsible for thinking, memory, emotions, movement, and all body functions. The brain receives information from the senses, processes it, and sends signals to different parts of the body. The human brain weighs about 1.3 to 1.5 kilograms and is made up of billions of nerve cells called neurons. These neurons communicate with each other through electrical and chemical signals. The brain has three main parts: Cerebrum – The largest part of the brain, responsible for thinking, learning, memory, speech, and voluntary movements. Cerebellum – Controls balance, posture, and coordination. Brainstem – Connects the brain to the spinal cord and controls vital functions such as breathing, heartbeat, and digestion. The brain is protected by the skull, layers of membranes called meninges, and a special fluid known as cerebrospinal fluid. It requires a constant supply of oxygen and nutrients from the blood to function properly. A healthy brain is essential for a healthy life. Proper sleep, balanced diet, exercise, and mental activities help keep the brain strong and active. If you want, I can also provide:
