The intramedullary course of the efferent salivatory fibers in the rat

Abstract

This study was made in an attempt to clarify the intramedullary course of the efferent salivatory fibers in the rat by using the Fink-Heimer method. These fibers took a course laterally from the salivatory uncleus to emerge from the brain stem. Apparently, they did not possess a genu in their passage. This result is contrary to those supposed by the electrophysiological method or the histochemical technique for cholinesterase.
