We explain to you how are the nuclei of nerve cells that are hidden under the brain surface. Absolutely each and every one of our motor, social or emotional capacities and abilities are governed and coordinated from the various structures that make up the entire brain. One of these systems are the subcortical structures of
This network of nerve cells associated with the digestive system is an essential component of the body. The enteric nervous system is the part of the autonomic nervous system in charge of regulating vital gastrointestinal functions. Among these functions are the regulation of the esophagus, stomach and colorectal functions; which in turn implies the absorption
These glands are responsible for producing hormones that fulfill a series of fundamental functions. Our endocrine system is made up of a set of organs and tissues that are responsible for regulating vital functions for our body through the release of different hormones. Aspects as important for survival as the proper functioning of the metabolism
Biology seems to have a pre-assigned role for each moment of our existence. Surely all of us have heard at some point in our lives that people are animals of habit. This expression, in addition to being true, hides an infinity of processes that our body performs to keep these habits at bay. These processes
These kinds of nerve cells are very characteristic of the human brain, as well as versatile. One of the most common classifications of neurons is the one carried out based on their morphology; more particularly, they are usually divided according to the number of dendrites and axons in their cell body. In this article we
This is how it is estimated that the brain of our bipedal ancestors changed. Our brain is one of our most complex and important organs, as well as one of the later to finish developing (and this without taking into account that throughout our lives we do not stop creating synaptic connections). It is a
Why should women rest more? Who doesn’t like to stay in bed a little longer in the morning or take a nap after eating to regain strength? If they asked us if there are differences between men and women in terms of the amount of sleep we need, and if they asked us which of
This part of the autonomic nervous system allows us to return to a state of rest after stress. There are multiple stimuli that trigger our alarm reactions. Stress, potential threats, alter us and cause an activation of the organism. This activation involves the consumption of a large amount of energy. However, after the moment in
We discover hormones and their multiple functions in our brain and body. Hormones are molecules of diverse nature that are produced in the secretory or endocrine glands. Working together with the nervous system, they are responsible for us acting, feeling and thinking as we do. The different types of hormones are released in the blood
What is the paracentral lobe? Let’s look at the characteristics of this region of the cortex of the brain. The cortex of the human brain contains various gyri and convolutions that delimit different brain regions and structures, each with its respective functions and interconnected with each other. One of them is the so-called paracentral lobe,
