BrainThe Greek word enképhalos derived in scientific Latin encephalos, which in turn came to our language as brain. This is how the group of organs found inside the skull and are part of the Central Nervous System of the Vertebrate animals.

The skull It is a structure of bones in whose cavity is the brain. The protection conferred by this bone sector is very important for life, since the brain directs most of the essential activities and actions for a human being.

The main part of the brain corresponds to the brain, which is divided into lobes. This organ is responsible for the control of the nervous system and is subdivided into forebrain or forebrain; midbrain or midbrain; Y rhombencephalon or hindbrain.

These three vesicles begin to develop from the four weeks of life of the embryo, when the neural tube has closed and the neural crest has formed. Let’s see below a detailed description of each of them and their respective parts. Let’s start with the forebrain, in which we find the telencephalon and the diencephalon. It is the largest part of the brain, and when observing it we can notice the right and left hemispheres.

The telencephalon is subdivided into a striatum, a rhinencephalon and a cerebral cortex, in which the following lobes are found: the occipital, the parietal, the temporal and the frontal, which cover functions as fundamental to our body as language, vision, organs of movement, hearing, smell and perception, among others. In particular, the frontal, the parietal and the temporal are in charge of learning, without which we could not develop and survive.

In the diencephalon we find the epithalamus, within which is the gland that produces melatonin, a hormone of great importance. There is also the thalamus, where sensations are controlled, the subthalamus, a structure that is linked to motor functions, and the hypothalamus, the center that regulates emotions and physical control, in addition to secreting the hormones oxytocin and vasopressin.

BrainRegarding the midbrain, we can say that it has four tubers that are related to vision (the two front) and hearing (the two back). In addition, it is responsible for filtering the data that passes between the rhombencephalon and the forebrain.

Finally, the rhombencephalon arrives, a portion that is located around the fourth ventricle of the brain and is made up of the myelncephalon and the metancephalon. It is located on the spinal cord and is made up of three parts: the bulb, the Varolian bridge and the cerebellum.

In turn, in the metancephalon we have the cerebellum, which allows the integration of motor pathways and sensory pathways, is responsible for the control of movement, posture and energy of the muscles. Returning to the myelencephalon, there we can notice the medulla oblongata (also known as brainstem), which controls some essential functions, such as breathing and the circulation of blood through the heart.

Since the medulla oblongata is an extension of the spinal cord, it is correct to affirm that it enables communication between it and the brain.

Brain problems can lead to all kinds of disorders and even death. Body control, memory and intelligence depend on the brain, with which damage to this set of organs has serious consequences.

The schizophrenia, the Parkinson’s disease, the Alzheimer disease and the Amyotrophic Lateral Sclerosis are some pathologies that affect the brain. There are also bacteria and viruses that, by generating a infection, alter its operation.
