The ability of bone to respond to the mechanical demands placed on it by changing its size, shape, and structure; the process involved in bone formation and destruction in response to hormonal, nutritional, and mechanical factors. Bones have to be mechanically stressed to remain healthy. They become heavier and stronger if gravity and muscle actions impose forces on them. Inactivity results in bone atrophy. See also Wolff's law.
