Cancellous bone is a type of osseous tissue with a low density and strength but very high surface area, that fills the inner cavity of long bones. The external layer of cancellous bone contains red bone marrow where the production of blood cellular components (known as hematopoiesis) takes place. Cancellous bone is also where most of the arteries and veins of bone organs are found.

Other names include trabecular bone and spongy bone. Its Latin name is substantia spongiosa or substantia spongiosa ossium.^[1] The words cancellous and trabecular refer to the tiny, lattice-shaped spicules that form the tissue.^[1]
