Bone tissue
（重定向自Osseus）
Bone tissue, or osseous tissue, is the major structural and supportive connective tissue of the body. Bone tissue forms the rigid part of the bones that make up the skeleton.
Bone tissue is different from bones themselves — bones are organs made up of bone tissue as well as marrow, blood vessels, epithelium and nerves, while bone tissue refers specifically to the bone mineral matrix that forms the rigid sections of the organ, and the bone cells within it.
