nervous system organization

The nervous system is the body's communication network, coordinating actions and responses. It consists of the brain and spinal cord (central nervous system) that process information, and nerves (peripheral nervous system) that carry signals to and from different body parts. Sensory receptors detect changes like touch or temperature, sending signals to the brain. The brain interprets these signals and issues instructions, such as moving a hand or feeling pain. This system ensures your body responds appropriately to its environment, maintaining harmony between thoughts, movements, and sensations.
