Comparation on Haversian system between human and animal bones by imaging analysis / 法医学杂志

ABSTRACT

OBJECTIVE@#To explore the differences in Haversian system between human and animal bones through imaging analysis and morphology description.@*METHODS@#Thirty-five slices grinding from human being as well as dog, pig, cow and sheep bones were observed to compare their structure, then were analysed with the researchful microscope.@*RESULTS@#Plexiform bone or oeston band was not found in human bones; There were significant differences in the shape, size, location, density of Haversian system, between human and animal bones. The amount of Haversian lamella and diameter of central canal in human were the biggest; Significant differences in the central canal diameter and total area percentage between human and animal bones were shown by imaging analysis.@*CONCLUSION@#(1) Plexiform bone and osteon band could be the exclusive index in human bone; (2) There were significant differences in the structure of Haversian system between human and animal bones; (3) The percentage of central canals total area was valuable in species identification through imaging analysis.
