初中动物学和生理卫生课本,都讲到小脑的主要机能是保持身体平衡,协调肌肉的运动。为让学生观察,我用麻雀做了演示实验,效果好,简便易行。方法如下: 实验材料与用具麻雀、解剖刀、剪子、竹针、胶布、棉花方法右手握住麻雀,轻轻拔去或剪去头颅骨上面的羽毛,弯曲麻雀的头颈,用食指和中指挤压着喙的基部,自头颅正中线切开头皮,露出头颅,用解剖刀慢慢削去小脑部位的头骨,待清楚的见到小脑后,自伤口 Junior high school zoology and physical health textbooks, are talking about the main function of the cerebellum is to maintain body balance, coordination of muscle movement. For students to observe, I use the sparrow demo experiment, the effect is good, simple and easy. Methods: Sparrows, scalpels, scissors, bamboo needles, tapes, cotton Methods Hold the sparrow with your right hand, gently unplug or cut the feathers above the skull, bend the sparrow’s head and neck, squeeze with the index finger and middle finger The base of the beak, cut the scalp from the midline of the skull, exposing the skull, slowly scalpels the skull of the cerebellum with a scalpel, to be clearly seen after the cerebellum, since the wound
