The two divisions that make up this portion of the brain are the pons and the cerebellum. The cerebellum is important to sensorimotor structure, if this portion of the brain is damaged a person looses the ability to control movements and change movements.The Myelencephalon is the most posterior division of the brain and is composed of tracts that carry signals between the brand and the body.he Telencephalon is the largest portion of the brain. This portion of the brain is in charge of voluntary movements, sensory input, and complex cognitive process (learning, speaking, and problem solving skills).
