Part I - Neuroendocrine Reflex Pathways Place the events associated with a complex neuroendocrine pathway in the correct sequential order. Use the phrases below regarding gastrointestinal coordination of protein digestion to put together a complex neuroendocrine reflex pathway in the correct sequential order. Rank from earliest to latest. To rank items as equivalent, overlap them.

meal containing protein enters the stomach, parietal cell releases hydrochioric acid, gastrin stimulates parietal cell, efferent neurons stimulate G cell, G cell releases gastrin into the circulation, Afferent neurons send information to nervous system in the gut lining

Solution

The neuro-intestinal reflex: As food is ingested by an individual, the afferent neurons send this information to the brain that food is now inside the stomach. This causes the efferent neurons to stimulate the G cells so that they could release gastrin in the blood. This gastrin has neurohormonal function which then activates the parietal cells to release hydrochloric acid. This causes lowering of pH and thus protein digestion begins in the stomach.

Thus, based upon above explanation, please find the correct sequence of events as below:
