Abstract
On an assumption that the development of human gastric ulcer may have some relation to the distribution of gastric artery, a detailed investigation was made on the arterial distribution in the gastric walls. First of all, distribution of the subserous artery of the gastric wall was investigated employing dogs in order to know the difference in arterial distribution by the region of the gastric wall.
Result of this investigation revealed that the arterial distribution was extremely thick in the region inside of the middle axial line and nearer to the lesser curvature. While, it formed the zona arterie perf orans around the middle axial line. In the region outside of the middle axial line, the distribution of small arteries formed arterial sparse network. In the region around the greater curvature, the dexter and sinister gastroepiploic arteries and the short gastric arteries formed the zona small arterie and, in its zona intermedius, they showed mutual anastomosis with the arterie recurrens.
