人体的组织,基本上可分四大类,即是上皮组织,结缔组织,肌肉组织和神经组织。这些组织在构造上有着明显的区别。如果我们把这些组织切片放在显微镜下要学生观察,就能使学生清楚的明确这一点。在目前某些中学的设备情况看,切片的种类不全,数量不多,因此,要在教学中即时的组织全体学生观察各种组织切片,以完成教学大纲的要求,就有了一定的困难。经过我们研究,这一困难是容易解决的。就是利用任何地区都易得到的一些材料(例如
The body’s tissues, basically can be divided into four categories, namely, epithelial tissue, connective tissue, muscle tissue and nerve tissue. These organizations have a clear structural difference. If we put these tissue slices under the microscope for students to observe, we can make it clear to students that. In the current situation of some secondary schools, there are not enough types of slices and a small number of them. Therefore, it is difficult to immediately organize all the students in teaching to observe various tissue slices in order to complete the requirements of the syllabus. After our research, this difficulty is easily solved. Is to use some materials that are readily available in any area (for example
