The rate at which the stomach empties into the duodenum depends on the type of food ingested. Food rich in carbohydrates leaves the stomach in a few hours. Protein-rich food leaves more slowly, and emptying is slowest after a meal containing fat. The rate of emptying also depends on the osmotic pressure of the material entering the duodenum. Hyperosmolality of the duodenal contents is sensed by "duodenal osmoreceptors" that initiate a decrease in gastric emptying, which is probably neural in origin. Which factor is responsible for increasing gastric motility?

The adrenal cortex is derived from mesoderm and begins posteromedial to the urogenital ridge. The adrenal medulla is derived from neural crest cells. These neural crest cells originate from the dorsal aorta. Clusters of chromaffin cells become the distinct medulla after birth. The adrenal gland first appears at 28-30 days post-conception. Adrenal medulla secretes?
