Desenvolvimento de modelos anatômicos para estudo do sistema circulatório de membros superiores humanos

Abstract

Students in the health area have the discipline of Anatomy as their curricular base. For theteaching-learning of this discipline to be effective, it is necessary that practical classes areapplied, associated with active teaching methodologies, in which students are motivated toparticipate in the class and interact with anatomical pieces. However, the study of thecirculatory system through the observation of vascularization in cadaveric pieces is especiallychallenging due to the loss of flexibility, volume and color retention of tissues, small size ofstructures and inadequate preparation of parts. In addition, there are anatomical variations, usually thereis a lack of new anatomical pieces for the classes and a great wear of thecadavers with continuous manipulation during studies. In this sense, the use of specialanatomical techniques has been shown to be an efficient resource in the preparation ofappropriate pieces and development of alternative didactic models that facilitate the learningprocess. Thus, this work aimed to develop three anatomical models of the human upper limbin previously fixed pieces, one by means of angiotechnics, another with vessel painting and athird with the application of both techniques, for a comparison on which model allowed betterobservation of the superficial veins of the upper limb and present them as options ofalternative cost-effective teaching materials for teaching in human anatomy. The modelprepared with painting of vessels proved to be the most valid alternative didactic resource andthat met the specificities of our objective regarding cost-benefit in the preparation of thematerial. The model prepared with angiotechnic and the model prepared with the combinationof both techniques were not valid due to the low efficiency of the angiotechnic when appliedin previously fixed parts due to its rigidity, being necessary further investigations, withpreparations before the fixation of the corpse, while the tissues still present elasticity andmalleability.
