Nervous System
The nervous system serves as the intricate network of communication within the human body, orchestrating a symphony of signals that governs every aspect of physiological and cognitive function. Comprised of the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, consisting of nerves that extend throughout the body, this complex system coordinates sensory input, motor responses, and higher-order cognitive processes. Understanding the structure and function of the nervous system is essential for comprehending human behavior, perception, and the mechanisms underlying various neurological disorders.
