Okay, so what’s the good part? WTF. Stimulation of acid secretion occurs as it does in the cephalic phase. Vagovagal reflex: Distention, or stretching, activates an afferent pathway which in turn stimulates efferent response from the dorsal nucleus of the vagus nerve. Neurogenic signals that cause the cephalic phase of gastric secretion originate from the cerebral cortex and in the appetite centers of the amygdala and hypothalamus.They are transmitted through the dorsal motor nuclei of the vagi and then through the vagus nerve to the stomach. There will also be an influence on G cells to increase gastrin circulation. [1], There is a small continuous basal secretion of gastric acid between meals of usually less than 10 mEq/hour.[4].
