The human brain is an incredibly complex organ that acts as the command center for the nervous system. It receives information from our senses and controls our thoughts, memories, emotions, and movements. Understanding its main parts helps us appreciate how we function every day. The brain is generally divided into three major components: the cerebrum, the cerebellum, and the brainstem.

The largest part of the brain is the cerebrum, which is responsible for higher-level functions like thought and action. It is divided into two hemispheres, and (21) __________ hemisphere is further split into four lobes. These lobes manage specific tasks such as vision, hearing, speech, and problem-solving. This is the part of the brain that allows us to learn new languages or solve difficult math problems.

Located at the back of the head, beneath the cerebrum, is the cerebellum. While much smaller than the cerebrum, it (22) __________ a crucial role in coordinating voluntary movements, balance, and posture. In addition, it helps to fine-tune motor skills, enabling us to perform smooth and precise actions like writing or playing a musical instrument. Without the cerebellum, our movements would be clumsy and uncoordinated.

The brainstem connects the cerebrum and cerebellum to the spinal cord. It is responsible (23) __________ regulating many essential automatic functions that we don't consciously control, such as breathing, heart rate, and sleep cycles. The signals that pass through the brainstem can directly affect our state of alertness and consciousness. It's a vital connection point that keeps our body's basic systems running.

In conclusion, while each part of the brain has distinct jobs, they all work together in a highly integrated way. The complex interplay between these parts is what makes human consciousness and ability possible. Every single action, from a simple reflex to a complex thought, (24) __________ by this remarkable network.

Life as a 14 or 15-year-old often feels like a constant juggling act.
