Cancellous bone, also known as trabecular or spongy bone, is a type of osseous tissue found at the ends of long bones, within the pelvis, ribs, skull, and vertebrae. Unlike the denser compact bone, cancellous bone has a porous, honeycomb-like structure, making it lighter and more flexible. This unique architecture allows it to absorb shock and support the metabolic activities of bone, such as the production of blood cells.
