Compared to cortical bone|compact bone (cortical bone), which is the other type of osseous tissue, it has a higher surface area but is less dense, softer, weaker, and less stiff. It typically occurs at the ends of long bones, proximal to joints and within the interior of vertebrae. Cancellous bone is highly vascular and frequently contains red bone marrow where hematopoiesis, the production of blood cells, occurs. The primary anatomical and functional unit of cancellous bone is the trabecula. Its Latin name is substantia spongiosa or substantia spongiosa ossium. It was first illustrated accurately in the engravings of Crisóstomo Martinez. Cancellous bone has a greater surface area in comparison with cortical bone, and as a consequence cancellous bone is ideal for metabolic activity e.g. exchange of calcium ions. In osteoporosis, cancellous bone is more severely ...
