How is cancellous bone arranged in the vertebral body?

• A. Osteons
• B. Lamellae
• C. Cortical bone
• D. Trabeculae

Answer: (D)

Vertebral cancellous bone is organized as a network of trabeculae. These thin, plate-like elements form a three-dimensional lattice with marrow-filled spaces between them. The trabeculae orient along the principal directions of load to efficiently resist the spine’s compressive forces, distributing stress while keeping the structure light. This lattice contrasts with cortical bone, which is dense and made up of osteons, and with lamellae as simply layered bone tissue, not the defining pattern of cancellous bone. So the cancellous architecture in the vertebral body is a trabecular lattice.
