Pyloruse

Pyloruse is a neologism used in speculative biology and fiction to denote a hypothetical regulatory mechanism at the pyloric region of the stomach that modulates gastric emptying in response to chyme composition. In these contexts, pyloruse is imagined as a sensing and signaling system that coordinates when and how quickly stomach contents pass into the duodenum.

Etymology and scope: The term combines pylorus, the distal stomach outlet, with the suffix -use to indicate a process. It is not part of standard medical nomenclature and has no formal definition in peer-reviewed gastroenterology sources. It appears mainly in worldbuilding, thought experiments, and some speculative science writings.

Proposed models: In speculative accounts, pyloruse might involve a mucosal sensor complex that detects pH, macronutrient content, or osmolality, relaying information through the enteric nervous system to influence smooth muscle tone of the pyloric region. It could interact with known hormonal pathways such as cholecystokinin or motilin to adjust the rate of gastric emptying and the composition of chyme entering the duodenum.

Clinical relevance and critique: As a fictional construct, pyloruse has no established clinical evidence. If considered, it would offer a conceptual framework for discussing gastric motility disorders, obesity therapies, and the balance between digestion and nutrient absorption, while remaining speculative until validated by research.
