You Can Taste Things With Your Anus
Researcher Bedrich Mosinger conducted a study in which he concluded that the tongue is not the only organ with taste receptors. “[The] function of taste receptors and signaling proteins outside of taste system is still unclear… [in some areas] they seem to be part of the chemical sensing of sugars or amino acids,” he said. “For the most part, though, full function of these extra-orally located taste receptors is unknown.” According to the study, the taste receptors are present in the stomach, intestines, pancreas, lungs, anus, testicles, and the brain.
