What is "nervous system"?

The nervous system is a complex network of specialized cells and tissues that coordinates and controls bodily functions. It includes the brain, spinal cord, and peripheral nerves, which transmit electrical signals and information throughout the body. The nervous system regulates voluntary and involuntary actions, processes sensory input, enables communication between different body parts, and facilitates higher cognitive functions such as thinking and memory. It plays a vital role in maintaining homeostasis, coordinating movements, and responding to external stimuli. The nervous system is integral to overall body functioning and is responsible for our ability to perceive, interpret, and interact with the world around us.
