Abstract
The literature contains numerous accounts of the effects on the thoracic and abdominal viscera of stimulation of the exteroceptors. There are, however, few accounts of the effects on the neuromuscular apparatus of stimulation of the interoceptors. The early meager literature is referred to in a study of skeletal reflexes induced by stimulation of the visceral afferent nerves in the frog and the turtle.1In a previous paper of this series2evidence was presented in support of the view that mechanical or electrical stimulation of the pulmonary fibers of the vagus nerve might exert an inhibitory effect on the nerve center controlling the knee jerk. The present paper purports to show that stimulation of the afferent fibers coming from the abdominal viscera may modify the knee jerk either by acting on the nerve center itself or by causing such changes in the skeletal musculature that the patellar jerk isKeywords
