The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, and hunger in our bodies. The brain and the spinal cord that radiates from it make up the central nervous system, or CNS.
What is the composition of the brain?
The brain of a typical adult weighs about 3 pounds and is 60% fat. Water, protein, carbohydrates, and salts make up the remaining 40%. In and of itself, the brain is not a muscle. Blood vessels and nerves, as well as neurons and glial cells, make up this structure.
What is the gray and white matter?
Gray and white matter are two different areas of the central nervous system. Gray matter refers to the brain’s darker, outer layers, whereas white matter refers to the brain’s lighter, inner layers. In the spinal cord, this sequence is inverted, with white matter on the outside and gray matter on the inside.
Gray matter is primarily composed of neuron somas (circular core cell bodies), whereas white matter is primarily composed of myelin-wrapped axons (long stems that connect neurons) (a protective coating). Due to the different makeup of neuron sections, the two appear as separate shades on some scans.
Each zone serves a particular purpose. Gray matter is in charge of data processing and interpretation, whereas white matter is in charge of data transmission to other parts of the nervous system.

What is the brain’s function?
The brain sends and receives chemical and electrical impulses throughout the body. Different signals, which your brain decodes, govern numerous operations. Some make you feel tired, while others make you feel uncomfortable.
Some messages are stored in the brain, while others are routed through the spine and the body’s vast network of nerves to distant limbs. The central nervous system does this with the help of billions of neurons (nerve cells).
The Major Components of the Brain
The three components of the brain that can be separated to a large extent are the cerebrum, brainstem, and cerebellum.
