The parenchymal distribution of the splenic artery was studied in order to obtain anatomical basis for partial splenectomy. Thirty two spleens were studied, 26 spleens of healthy horses weighing 320 to 450kg, aged 3 to 12 years and 6 spleens of fetus removed from slaughterhouse. The spleens were submitted to arteriography and scintigraphy in order to have their vascular pattern examined and compared to the external aspect of the organ aiming establish anatomo-surgical segments. All radiographs were photographed with a digital camera and the digital images were submitted to a measuring system for comparative analysis of areas of dorsal and ventral anatomo-surgical segments. Anatomical investigations into the angioarchitecture of the equine spleen showed a paucivascular area, which coincides with a thinner external area, allowing the organ to be divided in two anatomo-surgical segments of approximately 50% of the organ each.
Living anatomy is gaining increasing popularity as an alternative to the use of preserved cadaver specimens in musculoskeletal anatomy teaching. This article describes the development of a garment painted with musculoskeletal structures as an alternative to body painting. Garments offer some advantages over traditional body painting in anatomy teaching. The technique can be used across different disciplines, enhances students' ability to identify anatomic structures in living bodies, and provides insights into the topography of one or more body systems at the same time. The fact that garments are amenable to palpation by large groups of students with no damage to the painting favors repeated use in hands-on wet labs. Garments such as the one described in this article introduce a novel approach to interdisciplinary teaching and learning, which can be combined with traditional anatomy teaching methods. The first garment produced depicts part of the equine musculoskeletal system. Steps in garment construction are highlighted and indications, advantages, and limitations of the method discussed.
Anatomy is traditionally regarded as a difficult, non-motivating course involving a large body of theoretical and practical content, and it is often associated with high levels of dropout and failure. Given the relevance of the topic, we propose an alternative active multisensory teaching tool consisting of the construction of a low-fidelity anatomical model assembled into an articulated equine skeleton. Model construction and assembly assists students in the recognition of the topography and anatomical boundaries of the equine abdominal digestive system. Digestive system organs (liver, pancreas, stomach, small and large intestines) were constructed using common, easily available materials, such as newspaper, balloons, laminated rubber sheets, and polyethylene cylinders. The method described in this study is a low-cost, user-friendly teaching tool that is potentially applicable across different academic disciplines and that can also be used to construct models of other systems and species. However, it should be combined with other anatomy teaching methods because it does not provide detailed representation of specific digestive system organ features.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
