Yes, the backbone (also known as the spine or vertebral column) contains cartilage.
Cartilage in the Spine
While the sacrum and tailbone are composed only of bone and are immovable, cartilage plays a crucial role in other parts of the spine. This is mainly found in the form of spinal discs.
- Spinal Discs: According to the provided reference, each spinal disc is made up of:
- A soft, gel-like core.
- A tough, multi-layered outer case composed of fibrous cartilage.
Therefore, cartilage is an essential component of the backbone, specifically in the spinal discs located between the vertebrae.
