IS THE SMALL INTESTINE INNERVATED BY THE SO-CALLED SPINAL PARASYMPATHETIC NERVOUS SYSTEM?
1 The Department of Physiology, Medical College of Niigata, Japan
1. The stimulation of the splanchnic nerves always produces an inhibitory effect on the intestinal movements. After the application of nicotine to the solar plexus, the stimulation becomes ineffectual and gives no evidence of the excitatory effect, the existence of which is claimed by Kureé and his collaborators. Accordingly the existence of the so-called spinal parasympathetic nervous system regarding the innervation of the small intestine is very doubtful.
2. The stellate ganglia do not send any inhibitory fibre to the small intestine through the vagus nerves.
