The Brain

The brain stem plays an important role in basic attention, arousal, and consciousness. 
It contains the medulla oblongata, cerebellum, midbrain and pons. Its functions include things that you need to survive, such as breathing, digestion, heart rate, blood pressure, and arousal which makes you awake and alert.All information from our body passes through the brain stem on the way to the brain.

Medulla Oblangata

Pons is named after the Latin word for "bridge." The main job of this structure is to pass information between the cerebellum and cerebrum. In addition, it helps to send other messages to the brain, manage arousal feelings, and monitors respiration.

The cerebellum is a structure attached to the bottom of the brain. This part of the brain is important because it helps maintain your posture and balance. It also regulates voluntary actions such as running, clapping, or raising your hand. The cerebllum helps your bones make smooth and precise movements rather than jerky ones.

The midbrain is found between the hindbrain and forebrain and is one of the smallest structures. It controls many important functions such as seeing and hearing as well as eye movement.
