Human Brain

[00:00:04]Hello students. I am Lalit sir. Today's topic is the human brain. Let's understand it in simple language with the help of 3D animation.

[00:00:12]>> The human brain is the most important organ in our body.

[00:00:16]It is also called the control center of our body.

[00:00:20]>> Our brain controls everything we think, remember, speak, learn, or decide.

[00:00:28]Not only that, our emotions, body movements, balance, and coordination are also under the control of the brain.

[00:00:36]The brain and spinal cord form the central nervous system.

[00:00:42]Let us learn how it works.

[00:00:44]The brain is not a muscle. It is made up of billions of nerve cells, blood vessels, and supporting cells. Nerve cells are called neurons.

[00:00:55]These are the cells that exchange messages throughout the body.

[00:01:01]>> The brain functions with the help of electrical and chemical signals.

[00:01:05]These signals travel very quickly throughout the body.

[00:01:09]These signals help us experience [music] pain, feel sleepy, get hungry, and our body reacts instantly.

[00:01:16]>> Gray matter understands and analyzes information, while white matter transmits that information to the brain and other parts of the body.

[00:01:25]>> The brain has two main parts, gray matter and white matter.

[00:01:30]Both have different functions.

[00:01:32]Cerebrospinal fluid is found between these layers, which protects the brain from jolts and provides it with safety.

[00:01:40]>> The brain is protected by three protective layers around it around it called meninges.

[00:01:48]The human brain has three main parts, cerebrum, cerebellum, and brainstem.

[00:01:53]Each part has its own special function.

[00:01:56]First, let's talk about the cerebrum.

[00:01:59]It is the largest part of the brain and makes up about 85% of the entire brain.

[00:02:04]Now, let's talk about the cerebellum.

[00:02:07]It is located below and behind the cerebrum and is smaller in size.

[00:02:12]Now, we come to the brain stem.

[00:02:15]This is the important part that connects the brain to the spinal cord.

[00:02:21]>> The cerebrum also performs the task of understanding all the sensations we see, hear, touch, taste, and smell.

[00:02:28]So, remember, the cerebrum thinks, the cerebellum maintains balance, and the brain stem controls essential automatic functions for life.

[00:02:36]>> The cerebrum is divided into four main parts. These are called the frontal, parietal, temporal, and occipital lobes.

[00:02:44]The frontal lobe is located at the front of the brain. It controls thinking, planning, and decision-making, as well as problem-solving and speaking.

[00:02:52]>> When you solve a math problem, write an answer on an exam, or make a decision, your frontal lobe is activated.

[00:03:00]>> If a hot object touches your hand, the parietal lobe is the first to sense it, and the brain responds immediately.

[00:03:08]>> The temporal lobes, located on both sides of the head, control hearing, language comprehension, and memory.

[00:03:16]>> When you hear your teacher's voice, recognize a song, or remember a friend's name, the temporal lobe is working.

[00:03:24]>> Remember, the frontal lobe thinks, the parietal lobe feels, the temporal lobe hears and remembers, while the occipital lobe helps us see.
