The cerebrum is the largest part of the human brain, making up about 85% of the brain's total weight. It is responsible for many higher brain functions, including voluntary movement, reasoning, problem-solving, and complex thought processes. The cerebrum is divided into two hemispheres, each consisting of four lobes: the frontal, parietal, temporal, and occipital lobes. These lobes are crucial for processing sensory information, controlling motor functions, and housing areas responsible for language and emotional regulation.

The cerebellum, while an important structure located at the back of the brain, is significantly smaller than the cerebrum and primarily coordinates movement and balance. The brainstem, which connects the brain to the spinal cord, controls basic life functions such as breathing, heart rate, and blood pressure, but it is also smaller in size compared to the cerebrum. The limbic system plays a crucial role in emotions and memory but does not constitute the largest part of the brain in terms of physical size.
