Verified step by step guidance

Understand the structure of spongy bone: Spongy bone, also known as cancellous or trabecular bone, is characterized by a porous, honeycomb-like structure. It is found at the ends of long bones and in the interior of other bones.

Learn about osteons: Osteons, or Haversian systems, are cylindrical structures found in compact bone. They consist of concentric layers of calcified matrix and contain a central canal for blood vessels and nerves.

Differentiate between spongy and compact bone: Compact bone is dense and forms the outer layer of bones, while spongy bone is lighter and found inside bones. Osteons are a feature of compact bone, not spongy bone.

Clarify the misconception: Since osteons are specific to compact bone, spongy bone does not contain osteons. Instead, spongy bone is made up of trabeculae, which are small, needle-like pieces of bone that form a network.

Conclude the explanation: Based on the structural differences, the statement 'Spongy bone contains osteons' is false. Spongy bone has trabeculae, not osteons.
