The hypothesized areal inhibitory signal (normalized by volumetric signal strength), within a completed osteon, is plotted as a function of the cement line radius (R_C) for several values of the decay constant k (mm⁻¹). The radius of the Haversian canal is assumed to be 20μm. When k surpasses about 25 mm⁻¹, the inhibitory signal on the Haversian canal plateaus as the cement line radius (R_C) exceeds 100μm (0.10mm on the abscissa). S_NA is the inhibitory signal (S_N) per unit area (subscript A) on the surface of the Haversian canal. (Redrawn from Martin (2000a), figure 6, with permission of the author.)
