Osseous tissue is a type of connective tissue found in bone. It is the primary constituent of bone, creating the mineral matrix that makes bones hard, strong, and lightweight. Along with osseous tissue, the bones also include marrow, blood vessels, nerves, and epithelium, which covers the surface of the bone.
Bone is created from osseous connective tissue. Like other types of connective tissue, osseous tissue is composed of relatively sparse cells surrounded by an extracellular network, or matrix. Bone matrix is a tough, resilient mixture of protein and minerals.
