• (bone) Hard form of connective tissue that constitutes the majority of the skeleton of most vertebrates; it consists of an organic component (the cells and matrix) and an inorganic, or mineral component; the matrix contains a framework of collagenous fibers and is impregnated with the mineral component, chiefly calcium phosphate and calcium carbonate, which imparts the quality of rigidity to bone.

• (bone organ) Organ with cavitated organ parts, each instance of which has as its direct parts some maximal complement of compact (cortical) and cancellous bone, and some maximal complement of bone marrow cavities; together with instances of other bones, cartilages and joints, it constitutes some skeletal system. Examples: femur, sternum, maxilla, vertebra, talus.

• Bone, although strong, is a constantly changing tissue that has several functions. Bones serve as rigid structures to the body and as shields to protect delicate internal organs. They provide housing for the bone marrow, where the blood cells are formed. Bones also maintain the body's reservoir of calcium. In children, some bones have...

• Bone, rigid body tissue consisting of cells embedded in an abundant hard intercellular material. The two principal components of this material, collagen and calcium phosphate, distinguish bone from such other hard tissues as chitin, enamel, and shell. Bone tissue makes up the individual bones of...
