ABSTRACT
The preciousness of central neurons justifies the natural and ergonomic measures used to protect them. By far the most cells in the brain are not neurons, but rather glial cells. Various types of glial cells provide neurons with all nutrients and oxygen, remove wastes, protect them from toxins and bacteria with their lives, and physically hold the neurons in place.1 Thus diseases of central neurons are rare. However, they are vulnerable to trauma, and
to disease in their glial support system, as they cannot fend for themselves.
