1 INTRODUCTION Various corrosion cast and other models are routinely used in gross anatomical studies and teaching to improve the visualization of blood vessels (Anderson et al., 1989; Cirak et al., 2021; Kiełtykaka-Kurz et al., 2015; Meyer et al., 2007; Sanan et al., 1999; Zdun et al., 2019). Depending on the purpose of the model, the specimen may be fixed and soft tissues removed only to a degree to allow visualization of the routes of blood vessels among the soft tissue (Cirak et al., 2021).
