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 that the total number of osteocytes within the average adult human skeleton is ~42 billion and that the total number of osteocyte dendritic projections from these cells is ~3.7 trillion." 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 beneath table]), 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 beneath table]
(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)." |
