STUDIES ON THE DUAL INNERVATION OF THE DIAPHRAGM WITH SPECIAL REFERENCE TO TONUS AND NUTRITION

Abstract

The tonic and trophic innervation of the diaphragm in monkeys, dogs or rabbits, examined by various means, such as x-ray, chemical, bioelectrical and histologic methods, was found to be of dual nature, i.e., cerebro-spinal and autonomic. These 2 systems of innervation are adapted to compensate each other, and the creatin metabolism of the muscle is mainly related to the sympathetic innervation.
