The small, rod-like structures in cancellous bone that form a porous network are called?

• A. Trabeculae
• B. Lamellae
• C. Lacunae
• D. Volkmann's canal

Answer: (A)

In cancellous (spongy) bone, the supporting framework is formed by trabeculae—thin rod- or plate-like bony elements that weave together into a porous lattice. This lattice creates space for marrow and blood vessels while still providing strength and lightweight structure. Other terms describe different features: lamellae are the layered bone material inside compact bone’s osteons, lacunae are tiny cavities housing osteocytes, and Volkmann’s canals are channels that connect Haversian systems in compact bone. So the rod-like structures that form the porous network are trabeculae.
