Medical definition of the brain
The brain: It is a member of the nervous system, which is the CPU for all body control orders, whether voluntary or involuntary, to be the regulator of all body processes of all kinds.
Sections of the brain and its components
The brain tissue unit consists of millions of nerve cells, which are linked to each other in the form of neurotransmitters, which are very complex and perfect. These neurons differ in terms of function and structure: some of them transmit information in the form of neurological signals; they arise from neurotransmitters, It stores that information in a way that allows it to be retrieved in proportion to the function of the brain; therefore, the brain has been divided into major sections:
- Brain: The brain is the largest part of the brain, and occupies a high importance in controlling cognitive, sensory, and language functions.
- The cerebellum is a small spherical part located at the bottom of the brain that regulates motor functions and is called the body’s balance functions.
- The rectum is the lowest part of the brain; it is connected to the spinal cord, and it has controls for involuntary functions such as breathing regulation, heart beat, blood pressure, and other autonomic movements stored in the nervous system.
Brain food
The food provided to the brain is one of the most important meals to be given to the body! It consumes about 20% of the energy produced by the body’s food, by delivering food to it through the perfusion of its circulatory system. It contains essential brain substances that its cells rely on to produce the energy it needs; So the materials and factors involved in the process of energy production food for the brain, including:
Oxygen
Brain cells breathe oxygen; they consume up to 40% of the oxygen in the bloodstream; so oxygen depletion causes brain cells to die rapidly. The condition may develop into death or loss of certain brain functions, especially memory loss.
Sugar
Glucose is a source of energy for brain cells. Since there is no stored sugar in the brain, the brain needs to be maintained, especially in the morning.
Amino acids and fatty acids
Amino acids and fatty acids are the basic structure of the walls of the brain cells, which give it the control and support to facilitate the passage of nerve cells through them, so it is necessary to maintain these materials, and by strengthening them through food sources.
Metal
The brain needs minerals: in order to facilitate the function, to facilitate energy access, and to find the balance required for its nerve cells, such as: iodine, zinc, magnesium, selenium, iron, so choose the food rich in those elements.
Proteins and vitamins
Proteins and vitamins help the brain function by: neurotransmitters, neurotransmitter industry and its main structure, improving brain perfusion.
