Traditional methods of teaching anatomy to undergraduate medical and veterinary students are being challenged and need to adapt to modern concerns and requirements. There is a move away from the use of cadavers to new technologies as a way of complementing the traditional approaches and addressing resource and ethical problems. Haptic (touch)…

Advances in computer and interface technologies have made it possible to create three-dimensional (3D) computerized models of anatomical structures for visualization, manipulation, and interaction in a virtual 3D environment. In the past few decades, a multitude of digital models have been developed to facilitate complex spatial learning of the…

Results of a study designed to determine the effectiveness of implementing three-dimensional (3D) stereo images of a human skull in an undergraduate human anatomy online laboratory were gathered and analysed. Mental model theory and its applications to 3D relationships are discussed along with the research results. Quantitative results on 62 pairs…

Learning real three-dimensional (3D) anatomy for the first time can be challenging. Two-dimensional drawings and plastic models tend to over-simplify the complexity of anatomy. The approach described uses stereoscopy to create 3D images of the process of cadaver dissection and to demonstrate the underlying anatomy related to the speech mechanisms.…

The authors have created a software system called the CAVEman, for the visual integration and exploration of heterogeneous anatomical and biomedical data. The CAVEman can be applied for both education and research tasks. The main component of the system is a three-dimensional digital atlas of the adult male human anatomy, structured according to…

The increasing complexity of human body models enabled by advances in diagnostic imaging, computing, and growing knowledge calls for the development of a new generation of systems for intelligent exploration of these models. Here, we introduce a novel paradigm for the exploration of digital body models illustrating cerebral vasculature. It enables…

Learning embryology remains difficult, since it requires understanding of many complex phenomena. The temporal evolution of developmental events has classically been illustrated using cartoons, which create difficulty in linking spatial and temporal aspects, such correlation being the keystone of descriptive embryology. We synthesized the…

Assesses desktop-computer models that rotate in virtual three-dimensional space. Compares spatial learning with a computer carpal-bone model horizontally rotating at 10-degree views with the same model rotating at 90-degree views. (Author/CCM)

Understanding spatial relationships among anatomic structures is an essential skill for physicians. Traditional medical education--using books, lectures, physical models, and cadavers--may be insufficient for teaching complex anatomical relationships. This study was designed to measure whether teaching complex anatomy to medical students using…

Anatomy curriculum has changed dramatically around the world since the 1960s. These changes include the reduction of course hours, the abandonment of cadaver dissection, the use of problem-based learning, application of other teaching modalities such as prosected specimens, models, radiographic images, computer simulations, and the introduction of…

A study of 61 high school biology students found that Interactive Video Disk (IVD) simulation was as effective as actual frog dissection in promoting student learning of frog anatomy and dissection procedures. When used as a preparation for dissection, IVD simulation helped students perform better dissections and learn more from doing dissections.…

Reports on a study that examined the prior use of simulation on frog dissection in improving students' actual dissection performance and learning of frog anatomy and morphology. Finds that students who performed the simulation before dissection performed significantly better than students who performed dissection before using the simulation or…

The objectives of this study were to: examine the potential interaction between students' epistemological beliefs and placement in a simulation condition (constructivist versus non-constructivist) on conceptual development; and to assess whether a constructivist computer simulation experience would result in a greater degree of conceptual change…

Despite a long tradition, conventional anatomy education based on dissection is declining. This study tested a new virtual reality (VR) technique for anatomy learning based on virtual contrast injection. The aim was to assess whether students value this new three-dimensional (3D) visualization method as a learning tool and what value they gain…

The human brain contains an estimated 100 billion neurons, and browsing the Web, one might be led to believe that there's a Web site for every one of those cells. It's no surprise that there are lots of Web sites concerning the nervous system. After all, the human brain is toward the top of nearly everyone's list of favorite organs and of…
