Abstract
Both humeri were removed from 5 day old rats, and the periosteum of 1 bone (the experimental bone) was divided circumferentially near either its proximal or distal metaphysis. The bones were placed subcutaneously in older sex-matched isohistogenic hosts and removed 14 days later. All humeri increased in length. The experimental humeri were longer and thinner than those humeri where the periosteum was not cut. In the experimental humeri an overgrowth occurred at the end further from the site of division. The periosteum evidently was, as a result of growth plate activity, under tension; changes in periosteal tension affected both the growth in length and the deposition of new subperiosteal bone.
