  1. spine

    A spine is the column of vertebrae extending from the skull to the pelvis; also known as the backbone or vertebral column. It serves as a main support structure of the body, allowing us to stand upright, bend, and twist. The spine also protects the spinal cord, a pathway for messages between the brain and the rest of the body. In a broader context, the term spine can also refer to a sharp, pointed structure in animals or plants.
