Then metencephalon create a bulge called the pons, cerebellum and reticular formation , the pons is art of metencephalon that located on the brain stem that form a bulge that involve in motor control, and in the back of our brain the cerebellum is responsible for sensorimotor function that regulates posture ,balance and coordination, and the reticular comprise of two columns of neuronal nuclei defined boundaries go up to the medulla and into the mesencephalon plays the role in arousal and regulates our sleep and wake cycle. The mesencephalon is like metencephalon that has two division and the two are tetum and tegmentum, the function of mesencephalon includes controlling the responses to sight, eye movement, pupil dilation and body movement, also hearing. The diencephalon is composed of two structures the thalamus and hypothalamus. The two lobe structure
