[Composition and excitability of afferent fibers of the pelvic nerve in cats].

The afferent fibers excitable by pelvic nerve stimulation were as follows: A (81 m/sec), A (59.6 m/sec), A (45.3 m/sec), A (17.9 m/sec), A (31.6 m/sec), B (11.3 m/sec). We failed to find C fibers. Analysis of the distribution of fibers showed that the majority of them entered the S2 dorsal root (DRS2). The fast-conducting fibers (Abeta1 and Abeta2) were found at DRL7--DRS2. The number of slow-conducting fibers increased in caudal direction. The most abundant in the pelvic nerve are Abeta3 fibers, and somewhat fewer in number are Abeta and Agamma fibers.
