以往我们在进行两栖类解剖课时对学生的要求是:通过解剖观察,使学生对蛙或蟾蜍的内外构造进一步得到巩固,并初步掌握解剖蛙或蟾蜍的方法。本学期我们上解剖课时在原有要求上加了一条,就是解剖它们的胃,观察它们的食物,以明确对人类的关系。由于青蛙运动灵活,不易捕捉,学生们往往捕捉蟾蜍来作为两栖类解剖课的实验材料,因此我们要求学生在解剖观察蟾蜍的消化器官同时解剖它们的胃(蟾蜍应是捉来不久的,胃里食物尚未消化,时间久了胃中
In the past, we conducted the Amphibious Anatomy Class for our students to request that: Through anatomical observation, students should further consolidate the internal and external structures of the frog or the toad and master the methods of dissecting the frog or the toad. This semester we added an original requirement on the anatomy class, is to dissect their stomach, observe their food, in order to clarify the relationship between humans. Because frogs are flexible and difficult to catch, students tend to capture toads as experimental materials for amphibian anatomy. We therefore urge students to anatomically look into the digestive organs of toads while dissecting their stomachs (toads should be caught in the near future, Food has not yet digested, a long time in the stomach
