Brainstem, Cerebellum, Diencephalon, Cerebrum
The brain stem controls the flow of messages between the brain and the rest of the body, and it also controls basic body functions such as breathing, swallowing, heart rate, blood pressure, consciousness, and whether one is awake or sleepy.
The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.
The diencephalon relays sensory information between brain regions and controls many autonomic functions of the peripheral nervous system. It connects structures of the endocrine system with the nervous system and works with the limbic system structures to generate and manage emotions and memories.
The cerebrum is the largest part of the human brain, associated with higher brain function such as thought and action
