What is the ans nervous system?

The nervous system is a complex network of cells and tissues that coordinates the body's responses to internal and external stimuli. It consists of two main parts: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which connects the CNS to the rest of the body. This system is responsible for processing sensory information, controlling movements, and regulating bodily functions through a series of electrical signals. Overall, it plays a crucial role in maintaining homeostasis and enabling communication within the body.
