Abstract
Approximately 30% of the axons in the L6 and S1 ventral roots in the rat are unmyelinated. Appropriate surgical procedures show that 30% of these unmyelinated axons arise from dorsal root ganglion cells and are therefore presumably sensory. Thus approximately 10% of the total number of axons in these ventral roots are sensory. The other 70% of the unmyelinated axons come from the spinal cord and are therefore presumably preganglionic parasympathetic fibers. Thus approximately 20% of the axons in these ventral roots are unmyelinated preganglionic fibers. The implications of these findings are discussed.This publication has 26 references indexed in Scilit:
