Abstract

Three dimensional evaluation of internal structures of small bones with histological methods or conventional X-ray is difficult. Micro-computed tomography (µCT) can provide 3D datasets with high resolution. In this study we applied µCT to analyse tail vertebra of autotomizing lizards. Autotomy is an ability of several reptile families to loose their tail at predicted break points (autotomy plane) to escape from enemies. Until now, these autotomy planes have been described with histological and conventional radiographic methods only. Micro-CT produced high resolution (15 µm voxel size) images clearly showing the autotomy plane in the 3D reconstructions as well as in 2D slices. Micro-CT proved to be of high value for the examination of the 3D position of autotomy planes in tail vertebra of different reptile species. Therefore, µCT will also be useful for the evaluation of 3D bone microarchitecture in other biological research.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
