Fishes sense weak water motion using the lateral line. Among the thousands of described fish species, this organ may differ in size, shape and distribution of individual mechanoreceptors or lateral line canals. The reasons for this diversity remain unclear, but are very likely related to habitat preferences. To better understand the performance of the organ in natural hydrodynamic surroundings, various three-dimensional imaging datasets of the cephalic lateral line were gathered using Leuciscus idus as representative freshwater teleost. These data are employed to simulate hydrodynamic phenomena around the head and within lateral line canals. The results show that changes in canal dimensions alter the absolute stimulation amplitudes, but have little effect on the relation between bulk water flow and higher frequency signals. By contrast, depressions in the skin known as epidermal pits reduce bulk flow stimulation and increase the ratio between higher-frequency signals and the background flow stimulus.

Virtual movement of the ankle and subtalar joints using cadaver surface models. Int. J. Morphol., 33(3):888-894, 2015. SUMMARY:Medical students in the dissection room do not fully understand the ankle joint for dorsiflexion and plantar flexion as well as the subtalar joint for inversion and eversion. Thus, a three-dimensional simulation of the movements would be beneficial as a complementary pedagogic tool. The bones and five muscles (tibialis anterior, tibialis posterior, fibularis longus, fibularis brevis, and fibularis tertius) of the left ankle and foot were outlined in serially sectioned cadaver images from the Visible Korean project. The outlines were verified and revised; and were stacked to build surface models using Mimics software. Dorsiflexion and plantar flexion were simulated using the models on Maya to determine the mediolateral axis. Then, inversion and eversion were done to determine the anteroposterior axis. The topographic relationship of the two axes with the five affecting muscles was examined to demonstrate correctness. The models were placed in a PDF file, with which users were capable of mixed display of structures. The stereoscopic image data, developed in this investigation, clearly explain ankle movement. These graphic contents, accompanied by the sectioned images, are expected to facilitate the development of simulation for the medical students' learning and the orthopedic surgeons' clinical trial.

“…The model portrays several aspects of the external as well as the internal anatomy of an extracted maxillary first molar. The creation of PDF-embedded 3D models has previously been described in detail [99][100][101][102][103] and recent advances now permit the streamlined and standardized creation of such files using open source software packages [104,105]. From the perspective of endodontic morphometrics research, calibrated 3D PDF models permit the additional numeric analysis of tooth shape by allowing measurements directly within the electronic document.…”

BackgroundProviding comprehensive knowledge of the anatomy of human teeth is one of the basic functions of dental education, because a thorough understanding of their internal structure is one of the prerequisites for any successful clinical intervention. Several techniques have traditionally been employed to study and visualize the complex internal organization of human teeth. In contrast to these invasive techniques, modern imaging systems permit non-invasive analyses of the three-dimensional structure of human teeth. Owing to the relative ease of acquisition, handling, and distribution of the respective data, digital imaging techniques will also significantly influence dental education. HighlightIn this article, a broad overview of traditional and modern techniques for the visualization of internal tooth structures is provided. Emphasis is placed on micro-computed tomography systems and their application in endodontics. In addition, 3 the results derived from a comparison of histology and micro-computed tomography are presented. Apart from its utility in basic research, digital data can also be employed to create interactive three-dimensional models that are particularly suitable for teaching purposes. ConclusionNon-invasive, three-dimensional imaging techniques, in particular the various modalities of computed tomography, have ushered in a new era of endodontic studies.Owing to their digital nature, the results derived from these techniques can not only be easily analyzed and distributed but also be rapidly integrated into the teaching materials. Recent studies as well as the data shown in the present contribution suggest that digital educational materials lead to an improved understanding of the complex anatomy of human teeth.
