What is "spine"?
The spine, also known as the vertebral column or backbone, consists of a series of individual bones called vertebrae, stacked on top of each other and separated by intervertebral discs. It runs along the center of the back. The spine provides structural support to the body, allowing for an upright posture and protecting the spinal cord, which is housed within the spinal canal. It plays a crucial role in facilitating movement, flexibility, and stability of the body. The spine also serves as an attachment site for various muscles, ligaments, and tendons, contributing to overall movement and coordination. Additionally, the spine helps distribute forces and absorb shock during activities such as walking, running, and lifting. Proper care and maintenance of the spine are essential for maintaining overall health and well-being.

What is a "spine"?
The spine is the part of a book that holds the pages together and connects the front and back covers. It typically displays important information, such as the book's title, author, and publisher's logo. The spine serves both a structural and aesthetic purpose, supporting the book's binding and often featuring decorative elements that allow the book to be easily identified when shelved. The condition of the spine is crucial for the book's durability, as it bears the weight of the pages and is subject to frequent handling.
