Bone tissue (osseous tissue) is a hard tissue, ... Cancellous bone is highly vascular and often contains red bone marrow where hematopoiesis, the production of blood cells, occurs. There are two types of bone tissue: compact and spongy.The names imply that the two types differ in density, or how tightly the tissue is packed together. The lacunae of osseous tissue contain _____. Compact bone is the denser, stronger of the two types of bone tissue (). Short, irregular, and flat bones have large marrow cavities in order to keep the weight of the bones light. The inorganic matrix consists of mineral salts, mostly calcium, that give the tissue hardness. This canal contains nerves, connective tissue and blood vessels. Irregularly arranged fibrous connective tissues are found in areas of the body where stress occurs from all directions, such as the dermis of the skin.
