Before entering fully into the meaning of the term cortex, we will proceed to know its etymological origin. In this case, we can state that it is a word that derives from Latin, exactly from the adjective "corticea" which, in turn, comes from the noun "cortex, corticis". This can be translated as "bark."
The Cortex is the surface or exterior sector from organs Vegetables and animals Also called bark the tougher and external part of certain foods . For example: "The young man decided to carve his name in the bark of the tree", "Doctors did not detect damage to the cerebral cortex", "Before preparing the sandwiches, I will remove the crust from the bread".
It can be said that, in woody plants, the bark is the outer layer of roots and stems. Its function is to provide protection through its various tissues, such as phloem and the cork .
When talking about food, the bark is usually a part that is discarded due to its hardness. The cheeses , to name a case, they can have different kinds of bark: some are edible and some are not.
In relation to the gastronomic field we can not overlook the existence of another food that is called pork rind or pork rind. Basically it is the skin of the aforementioned animal that is usually fried, as a rule, to become a snack with an exquisite taste, although it is true that it is not precisely healthy due to the fats that it contributes to the body.
It is known as Earth crust to the outermost sector of the geosphere, which is the solid part of the planet land . The geosphere is made up of several concentric layers: the outer zone is the earth's crust.
It is possible to differentiate between continental crust (with an average thickness of about 35 kilometers, it forms the continental platforms and the continents ) and the oceanic crust (about 10 kilometers thick, it constitutes the oceans).
The cerebral cortex On the other hand, it is the nervous tissue that is responsible for covering the hemispheres of the brain . It has about 10,000 million neurons and houses the processes linked to thought and perception. In the cerebral cortex it is possible to recognize the archetype , the paleocortex and the isocortex .
The archetype is the part of the oldest cortex and is formed by the hippocampus. Its functions are both what are the physiological mechanisms and give automatic responses.
Paleocortex, on the other hand, is the part that has the peculiarity of finding between the oldest and the most evolved areas. In it is, for example, what is the olfactory part of the human being.
The isocortex, which is also known by the name of neocortex, is the one characterized by being the most current cortex. In this case, we can establish that it is what is responsible for what is logical thinking and reasoning.
Likewise, it must be taken into account that the cerebral cortex is composed of layers such as molecular, external pyramidal or external granular, among others.
