Abstract
Teaching internal structures obscured from direct view is a major challenge of anatomy education. High-fidelity interactive three-dimensional (3D) micro-computed tomography (CT) models with virtual dissection present a possible solution. However, their utility for teaching complex internal structures of the human body is unclear. The purpose of this study was to investigate the use of a realistic 3D micro-CT interactive visualization computer model to teach paranasal sinus anatomy in a laboratory setting during pre-clinical medical training. Year 1 (n = 79) and Year 2 (n = 59) medical students undertook self-directed activities focused on paranasal sinus anatomy in one of two laboratories (traditional laboratory and 3D model). All participants completed pre and posttests before and after the laboratory session. Results of regression analyses predicting post-laboratory knowledge indicate that, when students were inexperienced with the 3D computer technology, use of the model was detrimental to learning for students with greater prior knowledge of the relevant anatomy (P < 0.05). For participants experienced with the 3D computer technology, however, the use of the model was detrimental for students with less prior knowledge of the relevant anatomy (P < 0.001). These results emphasize that several factors need to be considered in the design and effective implementation of such models in the classroom. Under the right conditions, the 3D model is equal to traditional laboratory resources when used as a learning tool. This paper discusses the importance of preparatory training for students and the technical consideration necessary to successfully integrate such models into medical anatomical curricula.

Abstract
Despite the development of novel teaching strategies and the abundance of adjunct teaching web resources, students and early career physicians have continuously reported difficulties in learning and clinically applying neuroanatomy. Differences in instructional design of these resources, the lack of assessment of their capacity to meet intended educational goals, and a poor understanding of the user's perspective may have hindered their success in increasing understanding and retention of neuroanatomical knowledge. To decipher the limitations of existing web resources, an online search for neuroanatomy web resources was performed and distilled through a strict filtration rubric. A selection of resources were analyzed by a panel of educators and rated using Likert scales, focusing on the identification of features influencing their usefulness in learning the anatomy of the spinal pathways. The top three ranked web resources were subsequently evaluated by a panel of medical and neuroscience students to assess how specific features aided in their learning of the subject. This detailed analysis has identified features of neuroanatomy web resources that are valued by both educators and users with regard to instructional design. One resource was rated highest by end users and educators on a series of Likert scale questions in terms of clarity of explanation, step-wise teaching design, summarization of information, control of instructional-pace, integration with neurophysiology, neuroradiology and clinical correlates, deployment of a wide array of pedagogical tools, and factors for visualizing neuroanatomical inter-relationships. These results have provided a novel user perspective on the influence of specific elements of neuroanatomy web resources to improve instructional design and enhance learner performance.

Abstract
Although cadaveric dissection has historically been the cornerstone of anatomical education, it comes at the cost of some emotional, moral, safety, and environmental concerns. Computer assisted learning (CAL) programs are an increasingly common solution to these issues; however, research regarding the efficacy of high fidelity simulation is limited. The traditional first semester veterinary gross anatomy course curriculum at Ross University School of Veterinary Medicine (RUSVM) was supplemented with a web based virtual anatomy program, IVALA™ (www.ivalalearn.com). The purpose of this study was to assess the relationship between supplementary use of the IVALA™ program and student examination scores, and to measure student perception surrounding IVALA™. IVALA™ uses an interactive virtual canine specimen that enables students to identify, move, rotate, magnify, and remove individual anatomic structures while providing a text description of each selected anatomic point. Fifty-six first semester RUSVM students who supplemented their anatomic learning with the IVALA™ program performed significantly higher on examinations compared to students (n = 123) that did not (p = 0.003). Students’ overall perception toward IVALA™ was enjoyable (mean = 3.8 out of a 5-point Likert scale) and beneficial to their knowledge of anatomy (mean = 3.7); however, students did not support replacing cadaveric dissection with CAL (mean = 2.1). CAL can effectively supplement learning outcomes for veterinary anatomy.

Abstract
Until the late-twentieth century, primary anatomical sciences education was relatively unenhanced by advanced technology and dependent on the mainstays of printed textbooks, chalkboard- and photographic projection-based classroom lectures, and cadaver dissection laboratories. But over the past three decades, diffusion of innovations in computer technology transformed the practices of anatomical education and research, along with other aspects of work and daily life. Increasing adoption of first-generation personal computers (PCs) in the 1980s paved the way for the first practical educational applications, and visionary anatomists foresaw the usefulness of computers for teaching. While early computers lacked high-resolution graphics capabilities and interactive user interfaces, applications with video discs demonstrated the practicality of programming digital multimedia linking descriptive text with anatomical imaging. Desktop publishing established that computers could be used for producing enhanced lecture notes, and commercial presentation software made it possible to give lectures using anatomical and medical imaging, as well as animations. Concurrently, computer processing supported the deployment of medical imaging modalities, including computed tomography, magnetic resonance imaging, and ultrasound, that were subsequently integrated into anatomy instruction. Following its public birth in the mid-1990s, the World Wide Web became the ubiquitous multimedia networking technology underlying the conduct of contemporary education and research. Digital video, structural simulations, and mobile devices have been more recently applied to education. Progressive implementation of computer-based learning methods interacted with waves of ongoing curricular change, and such technologies have been deemed crucial for continuing medical education reforms, providing new challenges and opportunities for anatomical sciences educators.

Abstract
This article describes a chart-based approach for health sciences libraries to compare anatomy e-resources. The features, functionalities, and user experiences of seven leading subscription-based e-resources were assessed using a chart that was iteratively developed by the investigators. Acland's Video Atlas of Human Anatomy, Thieme Winking Skull, and Visible Body were the preferred products as they respectively excel in cadaver-based videos, self-assessment, and 3D graphical manipulation. Moreover, each product affords a pleasant user experience. The investigative team found that resources specializing in one aspect of anatomy teaching are superior to those that contain a wealth of content for diverse audiences.

Abstract
A trend in anatomical education is the development of alternative pedagogical approaches to replace or complement experiences in a cadaver laboratory; however, empirical evidence on their effectiveness is often not reported. This study aimed to evaluate the effectiveness of Anatomy Glove Learning System (AGLS), which enables students to learn the relationship between hand structure and function by drawing the structures onto a worn glove with imprinted bones. Massage therapy students (n = 73) were allocated into two groups and drew muscles onto either: (1) the glove using AGLS instructional videos (3D group); or (2) paper with palmar/dorsal views of hand bones during an instructor-guided activity (2D group). A self-confidence measure and knowledge test were completed before, immediately after, and one-week following the learning conditions. Self-confidence of hand anatomy in the 3D group gradually increased (3.2/10, 4.7/10, and 4.8/10), whereas self-confidence in the 2D group began to decline one-week later (3.2/10, 4.4/10, and 3.9/10). Knowledge of hand anatomy improved in both groups immediately after learning, (P < 0.001). Students' perceptions of AGLS were also assessed using a 10-pt Likert scale evaluation questionnaire (10 = high). Students perceived the AGLS videos (mean = 8.3 ± 2.0) and glove (mean = 8.1 ± 1.8) to be helpful in improving their understanding of hand anatomy and the majority of students preferred AGLS as a learning tool (mean = 8.6 ± 2.2). This study provides evidence demonstrating that AGLS and the traditional 2D learning approach are equally effective in promoting students' self-confidence and knowledge of hand anatomy.

Abstract
BACKGROUND The development of new technologies has provided medical education with the ability to enhance the student learning experience and meet the needs of changing curricula. Students quickly adapt to using multimedia learning resources, but these need to be well designed, learner-centred and interactive for students to become significantly engaged. CONTEXT One way to ensure that students become committed users and that resources become distinct elements of the learning cycle is to involve students in resource design and production. Such an approach enables resources to accommodate student needs and preferences, but also provides opportunities for them to develop their own teaching and training skills. INNOVATION The aim of the medical student research project was to design and produce an electronic resource that was focused on a particular anatomical region. The views of other medical students were used to decide what features were suitable for inclusion and the resulting package contained basic principles and clinical relevance, and used a variety of approaches such as images of cadaveric material, living anatomy movies and quizzes. The completed package was assessed using a survey matrix and found to compare well with commercially available products. IMPLICATIONS Given the ever-diversifying arena of multimedia instruction and the ability of students to be fully conversant with technology, this project demonstrates that students are ideal participants and creators of multimedia resources. It is hoped that such an approach will help to further develop the skill base of students, but will also provide an avenue of developing packages that are student user friendly, and that are focused towards particular curricula requirements.

Abstract
The interpretation of computed tomographs (CTs) and magnetic resonance images (MRIs) to diagnose clinical conditions requires basic knowledge of sectional anatomy. Sectional anatomy has traditionally been taught using sectioned cadavers, atlases, and/or computer software. The computer software commonly used for this subject is practical and efficient for students but could be more advanced. The objective of this research was to present browsing software developed from the Visible Korean images that can be used for teaching sectional anatomy. One thousand seven hundred and two sets of MRIs, CTs, and sectioned images (intervals, one millimeter) of a whole male cadaver were prepared. Over 900 structures in the sectioned images were outlined and then filled with different colors to elaborate each structure. Software was developed where four corresponding images could be displayed simultaneously; in addition, the structures in the image data could be readily recognized with the aid of the color-filled outlines. The software, distributed free of charge, could be a valuable tool to teach medical students. For example, sectional anatomy could be taught by showing the sectioned images with real color and high resolution. Students could then review the lecture by using the sectioned and color-filled images on their own computers. Students could also be evaluated using the same software. Furthermore, other investigators would be able to replace the images for more comprehensive sectional anatomy.

Abstract
BACKGROUND There is ongoing debate concerning the best way to teach anatomy. Computer-assisted learning (CAL) is one option for teaching anatomy and these resources are increasingly available. AIMS To assess the use of such resources in undergraduate medical student anatomy tuition. METHOD Literature review. RESULTS Eight quantitative studies were found and these tended to report favourably. Though these educational packages can show improvement in knowledge, the studies tended to cover small areas of anatomy or were assessed in short courses. There were also several assessments of learner's attitudes to CAL which tended to report favourably in terms of educational satisfaction and enjoyment. CONCLUSIONS There is insufficient evidence to show that these resources have a true place for replacing traditional methods in teaching anatomy. Further research should be conducted to determine how to use these resources in conjunction with current teaching methods or how their use can be integrated into the current anatomy curriculum.

Abstract
OBJECTIVE Existing neuroanatomical ontologies, databases and information systems, such as the Foundational Model of Anatomy (FMA), represent outgoing connections from brain structures, but cannot represent the "internal wiring" of structures and as such, cannot distinguish between different independent connections from the same structure. Thus, a fundamental aspect of Neuroanatomy, the functional pathways and functional systems of the brain such as the pupillary light reflex system, is not adequately represented. This article identifies underlying anatomical objects which are the source of independent connections (collections of neurons) and uses these as basic building blocks to construct a model of functional neuroanatomy and its functional pathways. DESIGN The basic representational elements of the model are unnamed groups of neurons or groups of neuron segments. These groups, their relations to each other, and the relations to the objects of macroscopic anatomy are defined. The resulting model can be incorporated into the FMA. MEASUREMENTS The capabilities of the presented model are compared to the FMA and the Brain Architecture Management System (BAMS). RESULTS Internal wiring as well as functional pathways can correctly be represented and tracked. CONCLUSION This model bridges the gap between representations of single neurons and their parts on the one hand and representations of spatial brain structures and areas on the other hand. It is capable of drawing correct inferences on pathways in a nervous system. The object and relation definitions are related to the Open Biomedical Ontology effort and its relation ontology, so that this model can be further developed into an ontology of neuronal functional systems.

Abstract
OBJECTIVES To develop a web-based module for learner instruction in the interpretation and recognition of osseous anatomy on craniofacial cone-beam CT (CBCT) images. METHODS Volumetric datasets from three CBCT systems were acquired (i-CAT, NewTom 3G and AccuiTomo FPD) for various subjects using equipment-specific scanning protocols. The datasets were processed using multiple software to provide two-dimensional (2D) multiplanar reformatted (MPR) images (e.g. sagittal, coronal and axial) and three-dimensional (3D) visual representations (e.g. maximum intensity projection, minimum intensity projection, ray sum, surface and volume rendering). Distinct didactic modules which illustrate the principles of CBCT systems, guided navigation of the volumetric dataset, and anatomic correlation of 3D models and 2D MPR graphics were developed using a hybrid combination of web authoring and image analysis techniques. Interactive web multimedia instruction was facilitated by the use of dynamic highlighting and labelling, and rendered video illustrations, supplemented with didactic textual material. HTML coding and Java scripting were heavily implemented for the blending of the educational modules. RESULTS An interactive, multimedia educational tool for visualizing the morphology and interrelationships of osseous craniofacial anatomy, as depicted on CBCT MPR and 3D images, was designed and implemented. CONCLUSIONS The present design of a web-based instruction module may assist radiologists and clinicians in learning how to recognize and interpret the craniofacial anatomy of CBCT based images more efficiently.

Abstract
OBJECTIVES This study aimed to implement innovative teaching methods--blended learning strategies--that include the use of new information technologies in the teaching of human anatomy and to analyse both the impact of these strategies on academic performance, and the degree of user satisfaction. METHODS The study was carried out among students in Year 1 of the biology degree curriculum (human biology profile) at Pompeu Fabra University, Barcelona. Two groups of students were tested on knowledge of the anatomy of the locomotor system and results compared between groups. Blended learning strategies were employed in 1 group (BL group, n = 69); the other (TT group; n = 65) received traditional teaching aided by complementary material that could be accessed on the Internet. Both groups were evaluated using the same types of examination. RESULTS The average marks presented statistically significant differences (BL 6.3 versus TT 5.0; P < 0.0001). The percentage pass rate for the subject in the first call was higher in the BL group (87.9% versus 71.4%; P = 0.02), reflecting a lower incidence of students who failed to sit the examination (BL 4.3% versus TT 13.8%; P = 0.05). There were no differences regarding overall satisfaction with the teaching received. CONCLUSIONS Blended learning was more effective than traditional teaching for teaching human anatomy.

Abstract
The difference between the idealization of anatomy atlases and the reality of human cadavers often frustrates gross anatomy students. To encourage students to celebrate rather than protest these differences, we describe a web site ARI (Anatomy Reports on the Internet) that allows students to document cadaveric findings online with photographs and text. We used several web languages for site construction, including mysql, php, html, and javascript. Faculty tools allow instructors to upload digital images of the structures, add relevant commentary, view and delete images, review submitted reports, and examine database statistics. Student tools allow dissection groups to choose and comment on images, enter and edit reports, and read reports submitted by other students. During the first two years of the site's use (2000-2001, 2002-2003), every dissection group at our institution submitted at least one report. Technical support requests were minimal.

Abstract
The exponential growth of medical knowledge presents a challenge for the medical school curriculum. Because anatomy is traditionally a long course, it is an attractive target to reduce course hours, yet designing courses that produce students with less understanding of human anatomy is not a viable option. Faced with the challenge of teaching more anatomy with less time, we set out to understand how students employ instructional media to learn anatomy inside and outside of the classroom. We developed a series of pilot programs to explore how students learn anatomy and, in particular, how they combine instructional technology with more traditional classroom and laboratory-based learning. We then integrated what we learned with principles of effective instruction to design a course that makes the most efficient use of students' in-class and out-of-class learning. Overall, we concluded that our new anatomy course needed to focus on transforming how medical students think, reason, and learn. We are currently testing the hypothesis that this novel approach will enhance the ability of students to recall and expand their base of anatomical knowledge throughout their medical school training and beyond.

Abstract
Functional Neuroanatomy, an interactive electronic neuroanatomical atlas, was designed for first year medical students. Medical students have much to learn in a limited time; therefore a major goal in the atlas design was that it facilitate rapid, accurate information retrieval. To assess this feature, we designed a testing scenario in which students who had never taken a neuroanatomy course were asked to complete two equivalent tests, one using the electronic atlas and one using a comparable hard copy atlas, in a limited period of time. The tests were too long to be completed in the time allotted, so test scores were measures of how quickly correct information could be retrieved from each source. Statistical analysis of the data showed that the tests were of equal difficulty and that accurate information retrieval was significantly faster using the electronic atlas when compared with the hard copy atlas (P < 0.0001). Post-test focus groups (n = 4) allowed us to infer that the following design features contributed to rapid information access: the number of structures in the database was limited to those that are relevant to a practicing physician; all of the program modules were presented in both text and image form on the index screen, which doubled as a site map; pages were layered electronically such that information was hidden until requested, structures available on each page were listed alphabetically and could be accessed by clicking on their name; and an illustrated glossary was provided and equipped with a search engine.

Abstract
In improving the teaching and learning of anatomical sciences, empirical research is needed to develop a set of guiding principles that facilitate the design and development of effective dynamic visualizations. Based on cognitive load theory (CLT), effective learning from dynamic visualizations requires the alignment of instructional conditions with the cognitive architecture of learners and their levels of expertise. By improving the effectiveness and efficiency of dynamic visualizations, students will be able to be more successful in retaining visual information that mediates their understanding of complex and difficult aspects of anatomy. This theoretical paper presents instructional strategies generated by CLT and provides examples of some instructional implications of CLT on the design of dynamic visualizations for teaching and learning of anatomy.

Abstract
This study evaluated the use of computer-based interactive imagery on students' achievement scores when compared with paper-based static imagery. It also assessed students' perceptions about the two imagery strategies and their different components. Sixty-four freshmen veterinary students (50 females, 14 males), enrolled in a comparative anatomy course, volunteered to participate in the study. This study used a pretest/posttest comparison group design and data was examined by analysis of covariance (ANCOVA). A close-ended questionnaire was administered to collect students' perceptions about the two imagery strategies. The mean difference in students' perceptions between the two strategies was analyzed using a two-tailed paired t-test. No significant differences were observed between computer-based interactive imagery and paper-based static imagery in the immediate recall of anatomical information. There was a significant difference in students' opinions toward the two strategies: students perceived computer-based interactive imagery as a better strategy in the assimilation of anatomical information than paper-based static imagery.

Abstract
RATIONALE AND OBJECTIVES To describe the development of and assess student satisfaction with a blended learning method for teaching radiologic anatomy that integrates web-based instruction with small group and didactic teaching. MATERIALS AND METHODS In 2002 the teaching of radiologic anatomy to first-year medical students was changed from group learning (20-30 students with a preceptor and films at a viewbox) to a blended learning model that included a brief didactic introduction followed by small group (7-8 students) web-based structured learning modules with rotating lab instructors. In 2003 the modules were changed to include self-study cases prior to the lab, follow-up cases, and twice-weekly optional review sessions. Students and lab instructors were surveyed for their response to the content and design of the sessions. RESULTS Course surveys in 2001, with a response rate of 84%, showed 58 negative comments regarding inconsistency between various instructors. Individual response rates for 2002 for radiologic anatomy teaching sessions (RadLab) surveys ranged from 56%-81%, dropping as the course progressed. All RadLabs were rated "very useful" or "useful," except the cardiovascular lab, which was not designed as an interactive module. In 2003, after redesign of the cardiovascular lab in the same format as the other labs, all RadLabs were rated 2.4 or better (useful). CONCLUSION An integration of computers with small and large group didactic instruction allow optimal use of faculty, conform to accepted theories of adult learning, and are well-accepted by students.

Abstract
The development of large semantic networks, such as the UMLS, which are intended to support a variety of applications, requires a flexible and efficient query interface for the extraction of information. Using one of the source vocabularies of UMLS as a test bed, we have developed such a prototype query interface. We first identify common classes of queries needed by applications that access these semantic networks. Next, we survey StruQL, an existing query language that we adopted, which supports all of these classes of queries. We then describe the OQAFMA Querying Agent for the Foundational Model of Anatomy (OQAFMA), which provides an efficient implementation of a subset of StruQL by pre-computing a variety of indices. We describe how OQAFMA leverages database optimization by converting StruQL queries to SQL. We evaluate the flexibility and efficiency of our implementation using English queries written by anatomists. This evaluation verifies that OQAFMA provides flexible, efficient access to one such large semantic network, the Foundational Model of Anatomy, and suggests that OQAFMA could be an efficient query interface to other large biomedical knowledge bases, such as the Unified Medical Language System.
