Abstract:"[Investigators] have used data from recent papers obtained by new imaging techniques, in order to estimate absolute and relative quantities of the human osteocyte network and form a more complete understanding of the extent and nature of this network." |

Abstract:"[Investigators] estimate the total length of all osteocytic processes connected end-to-end to be 175,000 km. Furthermore, [they] calculate that the total surface area of the lacuno-canalicular system is 215 m^2." p.147 left column 2nd paragraph:"The average surface area of a human osteocyte lacuna was reported in
[ref 31] to be 336.2 µm^2. Multiplying by the total number of osteocyte
lacunae (including empty lacunae), this corresponds to a total lacunar
surface area (Tt.Lc.S) of 11.8–17.7 m^2 (average of 14.7 m^2). The total surface
area of the human lacuno-canalicular network (Tt.LCN.S) is thus
212.4–218.3 m^2 (average of ~215 m^2)." p.148 right column 4th paragraph:"The surface area of the lacuno-canalicular network (Tt.LCN.S) is large, an estimated total of 215 m^2. This is more than that of a healthy adult lung (118 m^2) [primary source 62 beneath table], and much larger than the surface areas
of the gastrointestinal tract (32 m^2) [primary source 63 beneath table] and the skin (2 m^2) [primary source 64 beneath table]
(Table 3)." |
