The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing and olfaction.
The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.
The brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Brain, the mass of nerve tissue in the anterior end of an organism. The brain integrates sensory information and directs motor responses; in higher vertebrates it is also the center of learning. Learn more about the parts and functions of the brain in this article.
This fact sheet is a basic introduction to the human brain. It can help you understand how the healthy brain works, how to keep your brain healthy, and what happens when the brain doesn't work like it should. The Structure of the Brain
Your brain is an essential organ that allows you to perceive and interact with the world around you. It receives and interprets all the sensory information you encounter. A range of conditions can affect your brain. You can support your brain health by sleeping well, eating a healthy diet, exercising and making other healthy lifestyle choices.
The human brain is a complex organ, made up of several distinct parts, each responsible for different functions. The cerebrum, the largest part, is responsible for sensory interpretation, thought processing, and voluntary muscle activity.
The brain is an organ made up of neural tissue. It is not a muscle. The brain is made up of three main parts, which are the cerebrum, cerebellum, and brain stem. Each of these has a...
The human brain is roughly the size of two clenched fists and weighs about 1.5 kilograms. From the outside it looks a bit like a large walnut, with folds and crevices. Brain tissue is made up of about 100 billion nerve cells (neurons) and one trillion supporting cells that stabilize the tissue.
This three-pound organ is the seat of intelligence, interpreter of the senses, initiator of body movement, and controller of behavior. Read Brain Basics pages to learn more about how the brain works, and its important role in human health. The brain is one of the hardest working organs in the body.
