define osseous
Bone tissue. 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. Bones are organs that are made up of bone tissue as well as bone marrow, small blood vessels, epithelium and nerves. Bone tissue refers specifically to the bone mineral matrix that forms the rigid sections of the organ, and the bone cells within it. The two types of bone tissue are cortical bone and cancellous bone.
