Compact and Spongy bone-T.S.
Spongy bone, also known as cancellous bone or trabecular bone, is a porous, lattice-like bone tissue found in the ends of long bones and in the vertebrae, skull, and ribs. Its honeycomb structure, made of thin bony plates called trabeculae, helps to reduce bone weight, absorb stress, and provide space for red bone marrow, which produces blood cells.
