The human brain is a complex organ made up of several key structures, each with specific functions. The largest part, the cerebrum, is responsible for higher brain functions such as thought, memory, and voluntary movement. It is divided into two hemispheres, which are further divided into four lobes: the frontal lobe, parietal lobe, temporal lobe, and occipital lobe.
Beneath the cerebrum lies the cerebellum, which coordinates balance and fine motor skills. The brainstem, consisting of the midbrain, pons, and medulla oblongata, controls essential life functions such as breathing and heart rate. Together, these structures enable the brain to process information and
