GENERAL HISTOLOGY

Detailed explanation-1: -The spinal cord is a long, tube-like band of tissue. It connects your brain to your lower back. Your spinal cord carries nerve signals from your brain to your body and vice versa. These nerve signals help you feel sensations and move your body.

Detailed explanation-2: -(SPY-nul kord) A column of nerve tissue that runs from the base of the skull down the center of the back. It is covered by three thin layers of protective tissue called membranes. The spinal cord and membranes are surrounded by the vertebrae (back bones).

Detailed explanation-3: -Spinal cord – The longitudinal cord of nerve tissue enclosed in the spinal canal. It serves not only as a pathway for nerve impulses to and from the brain, but also as a center for operating and coordinating reflex actions independent of the brain.

Detailed explanation-4: -The spinal cord is composed of gray and white matter, appearing in a cross-section as H-shaped gray matter surrounded by white matter. The gray matter consists of the cell bodies of motor and sensory neurons, interneurons, and neuropils (neuroglia cells and mostly unmyelinated axons).

Detailed explanation-5: -The central nervous system is made up of the brain and spinal cord: The brain controls how we think, learn, move, and feel. The spinal cord carries messages back and forth between the brain and the nerves that run throughout the body.
