Anatomy teaching is seeing a decline in both lecture and laboratory hours across many medical schools in North America. New strategies are therefore needed to not only make anatomy teaching more clinically integrated, but also to implement new interactive teaching techniques to help students more efficiently grasp the complex organization of the human body. Among the difficult anatomical concepts that students struggle to understand, the anatomy of the peritoneal cavity with its complex projections of peritoneum could benefit strongly from new learning aids. In this report, an innovative teaching tool is presented to engage students during both lecture and laboratory, and help them build three‐dimensional (3D) mental maps of peritoneal cavity. The model consists of a patchwork of mesenteries and gut made from colored cloth stitched together onto a T‐shirt to denote the origin and outflow of each peritoneum projection. As the lecturer wears the life‐size model, the students can appreciate the 3D organization of the peritoneal cavity on a living body. In addition, the T‐shirt model can be used in parallel with dissection to ensure a strong reinforcement of the spatial understanding of the peritoneal cavity.

用ODO冷冻断裂法观察人膈腹膜间皮细胞和毛细血管的超微结构 总被引:1,自引:0,他引:1
ONO冷冻断裂法是一项新的扫描电镜制样技术。利用这项技术,将样品在-196℃下冷冻,然后把样品掰裂。用扫描电镜观察样品断裂面细胞的内部结构,具有较高的分辨率。并能显示细胞内部细胞器之间的关系。其缺陷是欲观察的断裂面不能预先确定,而是随机的。作者应用ODO冷冻断裂法,对人膈腹膜间皮细胞和毛细血管进行了观察. 相似文献

应用甲基丙烯酸甲酯毛细管铸型,对人胎膈腹膜毛细血管进行了扫描电镜观察.研究结果表明,人胎膈腹膜毛细血管的构型可分3种类型:(1)网囊型;(2)树枝型;(3)发丝型.在动脉性毛细血管的起始处,可见前毛细血管括约肌的压迹.本文并就人体膈腹膜微循环的功能作了讨论. 相似文献
