Method P.145 left column bottom paragraph:"[Investigators] combined data from the published literature with arithmetic calculations and mathematical models to provide novel quantifications of the osteocyte network system. Quantities taken from the literature and used in these quantifications are listed in Table 1 [BNID 111544] with their source. The major quantities derived in this paper are listed in Table 2 [BNID 111545] with the formula used to calculate them. Table 3 summarizes how these quantities compare with other organ systems in the body."
Comments p.148 left column top paragraph:"The total number of osteocytes in the human skeleton (42 billion) is in the same order of magnitude as previous estimates of the number of neurons in the brain (~86 billion [primary source 39]), and the total length of dendritic processes in bone (175,000 km) falls in the same range as the total length of nerve fibres in the human brain (150,000–180,000 km) [primary source 40] (Table 3). These cells are held within a total organ volume (1.75 L) that is larger than the average brain volume (1.2 L)." 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], and much larger than the surface areas of the gastrointestinal tract (32 m^2) [primary source 63] and the skin (2 m^2) [primary source 64] (Table 3). This area, and the related but slightly smaller total surface area of the osteocyte cell bodies, provide a remarkably large interaction interface for the small volume of extracellular lacuno-canalicular fluid (24 mL)."
