[Electrophysiologic and histomorphological studies on the nervus ischiadicus of rats. I. The uninjured nerves].
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%.
