This type of bone consists in a three-dimensional network of bone trabeculae that forms a system of large and irregular vascular cavities. These cavities contain blood vessels and bone marrow cells intermingled with loose connective tissue. Trabeculae are composed of bone lamellae of variable thickness (3-7 µm), which are distinct layers of extracellular matrix formed by parallel collagen fibers, and regularly distributed osteocytes.
