消化性潰痬是由於胃酸及胃蛋白酶的消化作用所引起的,所以只在胃腸道經常與酸性胃液所接觸之處才能産生,這是一般的說法。根據巴甫洛夫學說,胃酸的分泌是一種條件反射,當大腦皮質感受刺激時反射到下視丘的迷走神經中樞,由迷走神經的興奮促進胃的分泌,同時增强胃的運動,因此在大腦皮質興奮過度時,往往可以 Peptic ulcer is due to the digestion of gastric acid and pepsin caused, so only in the gastrointestinal tract and acidic gastric juice often come in contact with place, which is the general statement. According to Pavlov’s theory, gastric acid secretion is a conditioned reflex which is reflected in the vagal nerve center of the hypothalamus when the cerebral cortex is stimulated. Excitation of the vagus nerve promotes gastric secretion while enhancing gastric motility and is therefore excited in the cerebral cortex Excessive, often can
