The human brain is a very powerful organ. It controls the functioning of all the organs of the body. It also controls the thoughts and feelings of the person.
The human brain performs many functions like temperature control, human behaviour, blood circulation, respiration, sight, hearing, speech, etc. It is the most complex part of the body weighing about 1.5 kg and is protected by the skull. Therefore, there are different parts of the brain which control different functions of the body. Some important parts of the brain are:
Forebrain
Midbrain
Hindbrain

Where is the Brain Located?
The brain is the most powerful organ in the human body. It controls the functioning of our body. If anything happens to the brain, then the body will not work. So it's important to protect the brain. Therefore, it's located inside the hard-covering structure called the skull. It protects our brain from any kind of injury.
Functions of the Brain
The human brain is brilliant and complex. The brain is made up of many parts, each of which has a specific and important function. It controls our ability to balance, walk, talk and eat. It coordinates and regulates our breathing, blood circulation, and heart rate. It is responsible for our ability to speak, process, and remember information, make decisions, and feel emotions. Each brain is unique, ever-changing, and extremely sensitive to its environment.
Parts of the Brain for Kids
The human has three types of Brain:
Forebrain
The Middle brain
Hindbrain
The cerebrum, thalamus, and hypothalamus together make up the forebrain. The cerebrum is 80 to 90 percent of the human brain. The hypothalamus is located on the diencephalon part of the anterior brain (which is located at the base of the thalamus). This part gives knowledge of hunger, thirst, sleep, heat, fatigue, expression of emotions, etc.
The midbrain is not divided as any other part and the posterior brain includes the pons, cerebellum, and medulla.
The function of the hindbrain is to control changes in the head, neck, etc., in response to visual and auditory stimuli. It also regulates the movement of the eye muscles.

Interesting Facts About the Human Brain
Brain Facts for Kids:
The human brain weighs about 1336 grams.
The human brain is made up of 73% of water. Attention, memory, and other cognitive skills are affected if the body is dehydrated (dehydration or dehydration) even by 2%.
The Human Brain contains 86 billion brain cells.
The human brain grows to 3 times its size in the first year of life. It continues to grow till the age of about 18 years.
One million chemical reactions take place within the brain in 1 second.

FAQs on The Function of the Brain
1. What is the main job of the human brain?
The main job of the brain is to act as the control centre for the entire body. It's like a super-smart computer that manages everything we do, from thinking and feeling to moving and breathing. It receives information from our senses and tells our body how to respond.
2. What are some of the most important things our brain helps us do every day?
Our brain helps us with countless tasks every single day. Some of the most important ones include:
- Thinking and solving problems: Figuring out a puzzle or doing homework.
- Remembering things: Recalling a friend's name or what you learned in class.
- Moving our body: Walking, running, and playing.
- Feeling emotions: Being happy, sad, or surprised.
- Using our senses: Understanding what we see, hear, taste, touch, and smell.
3. What are the three main parts of the brain and their functions?
The brain has three main parts, each with a special job:
- Cerebrum: This is the largest part of the brain. It is responsible for thinking, learning, memory, and emotions. It is the centre of intelligence.
- Cerebellum: Located at the back of the brain, the cerebellum controls our balance, movement, and coordination. It helps us stand upright and move smoothly.
- Brain Stem: This part connects the brain to the spinal cord. It controls all the automatic functions we don't think about, like breathing, our heartbeat, and digesting food.
4. How does our brain help us see, hear, and taste things?
Our brain works with our sense organs to understand the world. Our eyes, ears, and tongue collect information and send it as tiny signals to the brain through special pathways called nerves. The brain then reads these signals and tells us what we are seeing, hearing, or tasting.
5. How does the brain 'talk' to the rest of our body to make us move?
The brain 'talks' to our body using the nervous system, which is like a network of tiny electrical wires. When you decide to kick a ball, your brain sends a command signal through the nerves to your leg muscles, telling them exactly how and when to move.
6. Why is it so important that the brain is protected by the hard skull?
The brain is very soft and delicate, similar to jelly. It can be easily damaged. The hard, bony skull, also known as the cranium, acts like a strong helmet. It protects the brain from bumps and injuries, keeping our body's control centre safe.
7. Does the brain shut down or sleep when we sleep?
No, the brain never completely shuts down. While we sleep, it is still very busy! It works to keep our heart beating and lungs breathing. It also uses this time to sort through memories from the day, store important information, and even create dreams.
