What is meaning of spinal cord?

The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain down the back. It serves as the main pathway for transmitting messages between the brain and the rest of the body, controlling movement, sensation, and other bodily functions. It is protected by the vertebrae of the spine and plays a crucial role in the central nervous system.

The spinal cord is a long, thin, cylindrical bundle of nervous tissue that extends from the medulla oblongata in the brainstem to the lower back. It is enclosed within the vertebral canal of the spinal column and is protected by the vertebrae, meninges, and cerebrospinal fluid. The spinal cord serves as the primary communication pathway between the brain and the rest of the body. It carries sensory information from the body to the brain and motor commands from the brain to the body. The spinal cord also contains reflex arcs that allow for rapid, involuntary responses to stimuli.
