Abstract

We report in the model described above on measurements of striking features of the normal sciatic nerve of adult male Wistarrats (250-300 g). Electrophysiological parameters were measured by means of an Electromyoneurograph (needle stimulation). The calculation of the maximum motor nerve conduction velocity results in a mean value of 59.6 ms-1. The mean compound action potentials of the foot muscle are 9.2 mV (proximal stimulated) and 10.1 mV (distal stimulated). Counting out 10011 nerve fibres in Light Microscoping Findings for histological studies we got a nearly Normal distribution of the fibre diameters with a mean fibre diameter of 7.09 microns. The corresponding density of nerve fibres is 8700.4 mm-2. The calculated percentage of neural tissue, related to the surrounding connective tissue is about 36.32%.

大鼠坐骨神经的电生理和组织形态学研究。(未受伤的神经)。
在上述模型中,我们报道了成年雄性wistarrat (250-300 g)正常坐骨神经的显著特征测量。电生理参数是通过肌电神经图(针刺激)测量的。计算最大运动神经传导速度的平均值为59.6 ms-1。足部肌肉的平均复合动作电位为9.2 mV(近端刺激)和10.1 mV(远端刺激)。对10011根神经纤维进行光镜观察,得到纤维直径接近正态分布,平均纤维直径为7.09微米。相应的神经纤维密度为8700.4 mm-2。计算出神经组织与周围结缔组织相关的比例约为36.32%。
