ACTION CURRENT BY THE MOVEMENT OF THE INTESTINAL SMOOTH MUSCLES IN THE BOWEL PART II. THE ACTION CURRENT AND THE MECHANISM OF THE INTESTINAL MOVEMENT

Generally in human intestinal movement there are 2 types of discharge pattern which are the small colon-movement and the coarse colon-movement, and the former is the group of 100~200 spikes and the latter is the group of 4~20 spikes.
By the experimental work-electric stimulating and denervating of extrinsic nerve or stimulating and denervating of nerves by the drugs, the author has found that the intestinal movement is controlled by the intrinsic nerve. The extrinsic nerve which regulates the intrinsic nerve, is not directory concerned in the intestinal movement.
The action current record of the narrow segment of congenital megacolon is especially interesting. In this respect, the author found that the intestinal movement was not by the automatic myogenic movement, but by the automatic impulses of intrinsic nerve.
The author applied this method in various functional disorders of the abdomen and has obtained the valuable data.
