Major part of brain

1. Medulla oblangata : It control center for involuntary function such as breathing

2.Pond relay information between from brain to cerebellum

3. Mid brain responsible for eye movement

4. Above mid brain is dicephalon which composed of two part Thalamus and hypothalamus which maintain homeostasis
