在中学生理课中,講到条件反射的实例时是非常生动的,尤其是当提到酸味的食物时,学生就会随着发生唾液分泌增多的反射活动,但这种活动只能自己来体会,如果装置唾液瘘管,作一次实际地观察,則更会提高兴趣,加深印象,对第一及第二信号系統活动的理解和記忆可以起到良好的效果。因此,制作唾液瘘使学生能够看到这方面的实驗,补上这个教学中的漏洞是十分必要的。 In high school students’ classes, it is very vivid to speak of examples of conditioned reflexes, especially when referring to sour foods, as students react to increased reflex activity of saliva, but this activity can only be felt on its own If you take a saliva fistula and observe it in real time, you will be more interested and more impressed. Your understanding and memory of the activities of the first and second signaling systems will work well. Therefore, the production of saliva fistula so that students can see this experiment, make up for the loopholes in this teaching is very necessary.
