Figure 1: 3-dimensional schematic representations of an idealized osteocyte-lacunar-canalicular system. (a) A schematic diagram of an osteocyte lacuna, where is the intermediate axis, the major axis, and the minor axis of the lacuna in the local coordinate system. Schematic diagrams of osteocyte lacuna and canaliculi, showing (b) osteocyte cell body (green) with processes (blue); (c) in - plane; (d) in - plane; and (e) in - plane.
