Which bone tissue has a porous structure that lightens the bone?

• A. Spongy Bone
• B. Compact Bone
• C. Innervated
• D. Vascular

Answer: (A)

Porosity in bone tissue is what keeps bone strong yet lighter. Spongy bone, also called cancellous bone, has a lattice of trabeculae with many small spaces in between. Those spaces make the bone much lighter than dense compact bone, while the trabeculae still run in directions that help bear loads. This porous network also creates room for marrow, which is important for blood formation and metabolic support. You’ll find spongy bone mostly at the ends of long bones and in the interior of other bones, where it helps with weight reduction without sacrificing strength. The other terms describe nerves or blood supply rather than a type of bone tissue, so they don’t account for the porous structure characteristic of spongy bone. So the bone tissue described is spongy bone.
