The five divisions of the brain are the Myelencephalon, Metencephalon, Mesencephalon, Diencephalon, and the Telencephalon. Myelencephalon The myelencephalon is also known at the medulla. This part of the brain is made up of tract that carries signal between the brain and the body. This part of the brain is the detrimental, which means that if any damage to this part of the brain can cause serious damage to the person’s brain and could even threaten the person’s life. There is part of the brain that is the reticular formation, which is also referred as the reticular activity system. It is referred to the reticular activity system because it plays a major role in the arousal stage. “Arousal is not the only function that the reticular formation is involved in; sleep attention, mobility, and the maintenance of muscle, as well as other cardiac, circulatory, respiratory reflexes”. Metencephalon The metencephalon is much like the myelencephalo. This is the part of the brain where the ascending and descending tracts are housed. This house creates a bulge that is called pons. This is located on the brains stem’s ventral surface. These pons are what make most of this division of the brain. The cerebellum is another large division that is located on the brain stem's dorsal surface. If any damage should happen to this portion of the brain it can make it where the ability to control movement and the ability to adapt to any change in the person environment or condition impossible to do. Mesencephalon This part of the have two division to it. Which are the tectum and tegmentum. The inferior colliculi holds the auditory functions and the visual functions. Within the tegmentum are three colorful structures that peak the interest of biopsychologists. These structures house the periaqueductal gray, substantia nigra, and the red nucleus.
