The researchers add that stress is also known to increase intake of salty foods. But in this study, the team did not find any GC receptors in taste buds associated with salty and sour tastes. Parker says this may be because stress could have an influence on salt taste processing in the brain. Taste buds are not only found on the tongue; they are also present in the gut and pancreas.
Types of papillae on tongue. by chzechze. No comments yet. Taste buds contain the receptors for taste. They are located around the small structures on the upper surface of the tongue, soft palate, upper esophagus and epiglottis, which are called papillae.These structures are involved in detecting the five (known) elements of taste perception: salty, sour, bitter, sweet, and umami. These papillae are mechanical and not involved in gustation. 2  They are characterized by increased keratinization. 3  Foliate papillae â these are ridges and grooves towards the posterior part of the roof of the mouth found on lateral margins.
