Cancellous bone (also known as trabecular, or spongy) 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.
The second type of osseous tissue is known as cortical bone, forming the hard outer layer of bone organs.
