The cell body contains the nucleus of astrocytes and is of a star shape - hence the name - because of the many cytoplasmic variously branched who leave. Astrocytes are characterized by abundance in the cytoplasm of a particular protein that identifies them. They also have a stock of sugar in the form of glycogen, which is the main energy reserve of the brain, because sugar is the favorite food neurons.
Astrocytes by their cytoplasmic extensions and questions intersecting contiguous, ensure the consistency and robustness of the brain structure and their extensions around completely capillaries, they contribute to the nutrition of neurons (which have no direct contact with the hair). Astrocytes are involved with neurons and other glial cells, the functioning of the CNS. They communicate with each other and exchange information with neurons through many joints communicating. In addition, they allow the selectivity of nerve transmission by preventing the diffusion of neurotransmitters. Astrocytes play a role important in September On the one hand, they work alongside microglia as antigen-presenting cells (specialized cells that are circulating foreign bodies, antigens to incompetent cells, lymphocytes), and secondly, they actively proliferate in the plates and are gradually edify a kind of scar glial who has undoubtedly adversely affect remyelination of axons stripped and regrow axons.
