vertebrae

The term 'vértebra' refers to a single bone in the spine that forms part of the vertebral column, which protects the spinal cord and provides structural support to the body. Each vertebra has a unique shape and structure that allows for flexibility and movement of the spine while also bearing weight. In humans and many vertebrates, the vertebrae are stacked on top of each other to form the backbone, which is crucial for maintaining posture and facilitating motion.
