What is spinal cord explain in very short and simple way

Answer 1

The spinal cord is a long, thin, tube-like bundle of nerves that runs down the middle of your back, inside your backbone or spine. It carries messages or signals back and forth between the brain and the rest of the body. It helps transmit sensations, such as pain and touch, and controls movements, like walking and lifting objects. In other words, it serves as a highway for the brain to communicate with different parts of the body.
