实验59.神经的特性目的——给予学生们有关神经兴奋性和传导性的概念。研究神经特性的实验是必须要做的实验。在本实验所叙述的两种实验方式中,第—种可供学生们实习时采用,而第二种则只能由教师向他们示教。在实验15中叙述过的第三种实验方式,也是为示教而介绍的。第一种实验方式材料及设备 1)一条刚被切下来的蛙腿;2)迦尔瓦尼氏叉;3)解剖刀;4)镊子两个;5)纯净的食盐结晶;6)柔软的毛笔;7)生理盐溶液(0.65％NaCl);8)5—6平方厘米的方纸块;9)制作实验标本用的小盘子或木板;10)盖玻璃片;11)氯 Experiment 59. Nervous Features Purpose - To give students the notion of neural excitability and conductivity. Experiments that study neurological properties are experiments that must be done. Of the two experimental approaches described in this experiment, the first one was available to students for internship, the second was to be taught only by teachers. The third experiment, described in Experiment 15, is also presented for teaching. The first experimental method Materials and equipment 1) a freshly cut frog leg; 2) a Galvani fork; 3) a scalpel; 4) two tweezers; 5) pure salt crystals; 6) Brush, 7) Physiological saline solution (0.65% NaCl) 8) Square paper of 5-6 cm2, 9) Small plates or boards for the preparation of experimental specimens 10) Cover glass 11)
