Meaning of Human Brain

What is Human Brain:

The human brain is a main and complex organ that is part of the nervous systemcontrols the vital functions of the human body and everything related to the senses, thoughts, movements, behaviors and reasoning.

The brain is protected by the bones of the skull in the anterior and superior part of the cranial cavity, where it is surrounded by cerebrospinal fluid that fulfills an immunological function and mechanical cushioning.

It should be noted that both human beings and vertebrate animals have a brain, with similar structures, but that function differently. For example, elephants have a larger brain than people, however, their reasoning ability is less.

Human brain

The brain has evolved over time, as well as the various species. Therefore, it has undergone significant changes from the primates to the evolution of the human being as it is known today.

Therefore, the studies around this organ start from the analysis of the data that we have of the ancestors of the human being, in order to understand how it has evolved until reaching the brain as we know it today and that characterizes the brain. Homo sapiens.

parts of the brain

Below are the parts of the brain.

Cerebral cortex

The cerebral cortex is the outer layer of the brain made up of neural tissue and nerve fibers that are responsible for carrying out cognitive and behavioral functions.

It is divided into the right hemisphere and the left hemisphere, in turn divided into four lobes: frontal, parietal, occipital and temporal.

Hard body

The corpus callosum is a sheet of white matter found at the base of the brain, connecting the two cerebral hemispheres with each other.

brain lobes

The brain has four lobes which are as follows:

  • frontal lobe: It is located in the anterior part of the brain and is responsible for controlling personality, creative and abstract thoughts, controlled movements, and voluntary muscle movements.
  • parietal lobe: It is located in the middle and lateral parts of the brain. Its main functions are to receive sensations such as cold or heat, among others, and body balance.
  • Occipital lobe: It is located in the back and is responsible for processing images, regulating vision and formulating thoughts.
  • Temporal lobe: It is located at the height of the ears and is responsible for controlling hearing, visual memory and language comprehension.

Brain functions

The brain is an organ that performs various functions, largely complex, that are vital for the proper functioning of the human body.

The brain constantly receives and interprets information that is necessary to act, respond to certain emotional circumstances, make decisions, respond to impulses, generate movements, determine sensations, among others.

Even the brain is also responsible for intervening in vital actions such as breathing, sleep, hormone release, controlling the nervous system, blood pressure, among others.

This allows us to interact with other individuals and take certain positions depending on the situation or environment in which we find ourselves. Hence, it is important to take care of and maintain the health of our brain.

brain characteristics

Below are the main features of the brain:

  • The adult brain has a volume of approximately 1100 cm3.
  • A healthy brain weighs between 1,300 g (in men) and 1,100 g (in women).
  • It is protected by the bones of the skull and the cerebrospinal fluid.
  • It receives about 25% of the total blood pumped by the heart.
  • It is made up of millions of neurons that make a complex connection with the brain, and that regulate the functions of our body and mind.
  • It carries out vital functions such as regulating temperature, blood pressure, hunger, breathing, sleep, among others.
  • Controls body movements and speech.
  • It carries out cognitive functions such as learning and memory.
  • Receives and processes information received through the senses.
  • It is a delicate organ, so it can suffer various diseases or damage.
