Abstract
The present study is an analysis of the ventral roots in the rat. The smallest myelinated fibers are found in segments T1-L2 and L6-S1. These fibers are regarded as preganglionic efferents and the L6-S1 outflow is more cranial than the sacral parasympathetic outflow in other animals. Large numbers of unmyelinated axons are seen in segments T1-L2 and L6-S1, the same segments that contain the smallest myelinated fibers. This data will be used as a baseline for determining the functional categories of the unmyelinated axons.This publication has 17 references indexed in Scilit:
