The superior colculos, act as reflected centers, that govern the movements of the eyes, the head and the neck, in reply the visual stimulatons and to other stimulatons. The inferior rises are reflected centers for the movements of the head and the trunk, in reply the stimulatons auditory. Mesencfalo contains diverse nuclei, also the left and the right, the black substances, that control the muscular activities, the red nuclei, rich sanguineous suppliment and of a pigment, I contend iron, in its neuronais cellular bodies. The known medial lemnisco as white substance, contains axnios that lead impulses related with the sensations of tato (TORTORA; GRABOWSKI, 2002). The cerebellum occupies the faces inferior and posterior of the craniana socket, located subsequent to the bulb and to the bridge, and inferior to the posterior part of the brain is separate of the brain for fiction transversa, and the tent of the brain. The previous wolf and the posterior wolf govern the subconscious movements of the esquelticos muscles; the wolf to flculo-nocular, in the inferior surface, is related with the direction of the balance.
One of the main functions of the cerebellum is to evaluate if the movements initiated for the motor areas, beyond co-ordinating the dependent movements of abilities, are the main one region of encfalo regulating of the position and rocking (TORTORA; GRABOWSKI 2002). Diencfalo extends of the enceflico trunk until the brain and surrounds the third ventricle; it includes the thalamus, hipotlamo, epitlamo and subtlamo. The thalamus is the main retransmissora station for the sensorial impulses in its way for the brain, come of the spinal marrow, of the enceflico trunk, the cerebellum and other parts of the brain. It allows the perception of some sensations as to the ones of pain, temperature and pressure. The nuclei, in each half of the thalamus, have some papers: the medial geniculado nucleus transmits impulses auditory; the lateral geniculado nucleus transmits impulses visual; the posterior ventral nucleus transmits impulses for the palate and the somatic sensations, as of tato, vibration, heat, cold (TORTORA; GRABOWSKI, 2002).
