Answer: D - Wolff’s Law relates to bone mass and distribution. Although it is true that the skeletal system’s general parameters are predetermined, every bone responds to its own microcosm of stimulation. German surgeon Julius Wolff hypothesized that when bone was stimulated - either by the pull of muscle or by compression and weight-bearing - that bone would produce more bone. One way to think of this is that “form follows function” - that bone will always prepare for the greatest load to be asked of it.
