The Central Nervous System (CNS) is a crucial part of the human body that includes the brain and spinal cord. It acts as the control center, processing information and sending signals throughout the body. The brain is responsible for thinking, memory, and emotions, while the spinal cord transmits messages between the brain and the rest of the body. The CNS works closely with the Peripheral Nervous System (PNS), which connects the CNS to limbs and organs. Together, they help us respond to our environment, control movements, and maintain vital functions like breathing and heart rate. Understanding the CNS is essential for studying how we think and act.
