Title: Partially burned human bone specimen

Description:
The human bone specimen was half burned causing denaturating and loss of collagen fibres in the burned part of the sample. Using polarisation microscopy the polarisation nicols were crossed completely in (A) and only half in (B). The corresponding osteons are numbered for identification in both photographs. Unburned collagen fibers are birefringing, while the burned osteons are not. The collagen fibres in the lamellae are arranged in a circular fashion. The intact osteones (left half) show classic polarisation pattern (Malthese Cross effect), the burned ones don’t, i.e. the right half.
