The hemispheres are connected at the bottom and have a deep groove running between them. The cerebrum is made up of the right and left cerebral hemispheres. The largest part of the brain, located in the front, is called the cerebrum. Arachnoid membrane: The middle layer of tissue.Pia mater: The layer closest to the surface of the brain.Inside the cranium, the brain is surrounded by three layers of tissue called the meninges. The cranium and the bones of the face make up the skull. The brain is protected by a bony covering called the cranium. The following information provides a brief description of some of the major parts of the human brain. Years of scientific study have made it possible for scientists to identify the various areas of the brain and determine their specific functions. While the brain only weighs about three pounds, it is a highly complex organ made up of many parts. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings-all the things that make us human. Take a ten question quiz about this page.The brain is arguably the most important organ in the human body. In a right handed person the left side of the brain is used for language and numbers while the right side is the more artistic side and is also used for recognizing objects. What each half does depends on whether you are left or right handed. Each half also controls specialized functions. Since the nerves cross when they enter the brain, the left side of our brain controls the right half of our body and the right side controls the left. The brain actually uses around twenty percent of the body's energy. There are lots of blood vessels and blood flowing through the brain at all times. Energy is sent to the brain by our blood. The brain may not move, but it needs lots of energy. We can't remember a lot of things in short term memory though, and, like its name suggests, these memories don't last very long. Scientists are still learning exactly how memory works, but they know that short term memory allows us to remember something for a very short time without rehearsing or practicing it. The brain has two kinds of memory, short term memory and long term memory. Also, many automatic functions are controlled here like keeping the heart beating, breathing, and digesting food. Brain Stem or Medulla - This is where the brain connects to the spinal cord.Hey, I didn't think about typing this once! The cerebellum can learn motor movements with practice allowing us to do stuff like riding a bike or typing without even thinking about it. It processes all the incoming motor messages from the nerves and figures out what to do with them. This part of brain deals with motor movement. Cerebellum - At the back and bottom of the brain is the cerebellum.Smart or thinking people are sometimes called cerebral. The back part deals with vision while other parts deal with other functions like movement, hearing, language, and touch. Different parts of the cerebrum deal with different parts of the body. The surface of the cerebrum is called the cerebral cortex. Cerebrum - The cerebrum is the biggest part of the brain.The brain also sends signals using nerves to muscles in order to make our body move. Nerves from our senses (hearing, seeing, touch, etc.) send signals to the brain to let the brain know what is going on in the outside world. The brain connects to nerves that travel throughout the body. Together with the spinal cord, it makes up the central nervous system. The brain sits in our hard, thick skull with membranes and fluid around it to protect it. It's a ball of gray looking wrinkled tissue about the size of two of your fists put together.
We remember, have emotions, solve problems, worry about stuff, dream about the future, and control our bodies in our brain.įor such an awesome organ, the brain doesn't look like much. All our senses are tied into our brain allowing us to experience the outside world.
