Irregular latticework of thin bony plates in spongy bone tissue is called?

• A. Trabeculae
• B. Lamellae
• C. Osteons
• D. Medullary cavity

Answer: (A)

In spongy bone the matrix forms a lattice of thin bony plates called trabeculae. This irregular, web-like network creates a lightweight yet strong framework that resists stresses from multiple directions and leaves spaces for marrow and blood vessels. The term trabeculae specifically describes this meshwork, which is why it’s the best match for the description. Lamellae are the layered rings of bone tissue found inside osteons in compact bone, not the lattice of spongy bone. Osteons, or Haversian systems, are the cylindrical units that make up compact bone. The medullary cavity is the hollow center of a long bone that houses bone marrow, not the spongy lattice itself.
