Central nervous system, Glial cells, EncephalonAbstract
The present article seeks through the literature review methodology to gather, analyze and synthesize the most recent information about the various functions performed by glial cells, focusing on the astrocytes as primordial for the proper functioning of the neural system. It was verified that throughout time there has been a centrality in the study of neurons, but that the most recent discoveries point to the need for a theoretical and scientific deepening in the astrocytes, which beyond the simple function of covering, perform several other fundamental activities. Among these activities two fronts stand out, the first being nutritional and structural support to the neurons. The second activity that stands out is the active participation in the composition of the blood-brain barrier. Recent findings indicate that the deficiency and malfunctioning of astrocytes are directly related to Alzheimer's disease, Parkinson's disease, and some forms of epilepsy, and are also correlated to memory and learning problems.
