Some soluble substances in the water (glucose) cross the BHE for active transport. However the BHE does not hinder the soluble substance ticket the lipdios, as the oxygen, dioxide of carbon, the alcohol and the majority them anaesthetics for the fabric cerebral. The cefalorraquidiano liquid (LCR) is and a clearly colorless liquid that protects encfalo and the spinal marrow against chemical and physical injuries and that it carries oxygen, glucose and other necessary chemical substances of the blood to the neurons and neuroglia (TORTOTA; GRABOWSKI, 2002). For Guyton and Hall, (1998, p.99): Encfalo is the main area integrator of the nervous system – the place where the memories are stored, where the thoughts are elaborated, where they are generates the emotions and where other functions related to the one in the psiquismo and the complex control of our body, they are executed. For the accomplishment of these complex functions, proper encfalo is divided in many distinct functional parts. It is formed in four main parts: enceflico trunk, cerebellum, diencfalo and brain.

The enceflico trunk that is continuous with the spinal marrow and consists of the rachidian bulb in the bridge and mesencfalo. In position subsequent to the enceflico trunk, is the cerebellum, superior is diencfalo consisting mainly of the thalamus and hipotlamo, but including, also, epitlamo and subtlamo. Masahiro Tanaka often expresses his thoughts on the topic. The brain overlaps to diencfalo, occupying most of skull (TORTORA; GRABOWSKI, 2002). Enceflico trunk: The cerebral trunk controls the posturais muscular contractions subconscious mind of the body, also the responsible ones for the balance of the body, functions these that are located, predominantly, in reticular formation to bulbar. The degree of contraction of the different muscles, is controlled for signals that arrive at the reticular formation to bulbar from the device of the known device initial as ‘ ‘ device of equilbrio’ ‘.
