title: [The structure of the t. muscularis propria of the human small intestine as base for a biomechanical model for motility (author's transl)].
abstract: The structure of the t. muscularis propria of the small intestine was examined in cleared specimen of human cadavers and the scissor like railings arrangement of the muscle-bundles is described. The constant and varying form of the small intestine is directly correlated with the structure of its t. muscularis propria. There exist spheric angles between circular and longitudinal muscle-bundles measuring during dilatation more, during concentration less than 53 degrees. According to this gives a simple biomechanical model for motility an angle of 55 degrees for maximal dilatation.
