PhysiologyThe intestinal phase plays a minor role in stimulating gastric secretion. However, it is crucial for inhibiting gastric secretion and motility once food enters the duodenum. Factors such as acidity, fatty acids, and osmolality of the duodenal contents trigger the release of hormones like secretin and cholecystokinin, which in turn inhibit gastric acid secretion.

Oral PathologyPagets disease shows a characteristic mosaic pattern of bone on radiographs due to irregular bone remodeling with alternating areas of bone resorption and formation. This creates a "jigsaw puzzle" or mosaic appearance with cement lines separating areas of old and new bone. Fibrous dysplasia shows ground-glass appearance, osteopetrosis shows marble bone appearance, and osteogenesis imperfecta shows thin cortices.
