Anatomy of the Brain

• The human brain consists of various regions, each with specific functions and structures.
• Major divisions include the cerebrum, cerebellum, and brainstem.
• The cerebrum is the largest part and is responsible for higher brain functions, including thought and action.
• It is divided into two hemispheres, which are further segmented into lobes: frontal, parietal, temporal, and occipital.
• The cerebellum coordinates movement and balance, playing a crucial role in motor control.
• The brainstem connects the brain to the spinal cord and controls vital functions such as heart rate and breathing.
• Within each lobe, various structures serve distinct roles, such as the hippocampus for memory and the amygdala for emotional processing.
• The brain is protected by the skull and surrounded by three layers of membranes called the meninges.
• Cerebrospinal fluid circulates around the brain, providing cushioning and nutrients.
