The brain in the human body

The human body consists of a group of parts that work in an integrated manner to carry out various vital functions, and one of the most important of these parts is the brain, which is located specifically in the head area on the upper side of the spinal cord, so that it extends in the form of a group of nerve cells that extend from the neck to the spine It constitutes the main center for controlling the human body by receiving information from the rest of the organs, specifically the sensory ones, in order to analyze them and send information that regulates their movement and functions, in addition to storing information related to previous experiences to help people remember and learn as well. The brain is the main source of your thoughts and mood. And your emotions too.

its installation

The human brain differs from the brain of other organisms. For example, in insects and worms, it consists of neurons present in the form of small groups. As for animals that have a backbone, their brain is more complex, as it consists of a group of many parts, and is more developed than the brain of monkeys, for example, and whales. In addition to dolphins.

As for the human brain, it is finer and more accurate, as it consists of cells connected and interconnected with each other in a complex way, the number of which may reach billions; In order for a person to be able to use languages ​​as well as solve problems, especially complex ones, in addition to creativity in the field of artwork, and its shape is specifically a gray-pink ball, and it contains a gel, and its surface is bumps and grooves, while its weight is for a newborn child equivalent to half a kilogram and often less And when he reaches the age of six years, his brain weighs one and a half kilograms, which is the largest weight the brain can reach. The secret behind the increased weight of the brain is the growth of the group of neurons and supportive brain cells, in addition to the connections that connect brain cells to each other.

feed it

The brain gets what it needs from food and oxygen through blood vessels. Although the brain does not take more than 2% of the body weight as a whole, it consumes a large amount of oxygen, up to 20% of the total amount of oxygen consumed by the body when it is in A state of rest and relaxation, and according to many studies, the period during which the brain can give up oxygen does not exceed five minutes only, after which it becomes exposed to many risks.

its parts

The brain is made up of three main sections or parts, which include:

* The brain.

* cerebellum.

* brainstem.

So that each part of it consists of a group of nerve cells called neurons, in addition to supporting nerve cells called glia.
