1. Dorsal Curvature

   Linked via "oxygen saturation"

   If the tongue dorsum exhibits insufficient curvature (i.e., becomes overly flattened or convex), the resultant pressure gradient during the pharyngeal stage fails to achieve the necessary laminar flow characteristics for efficient transport. This leads to the phenomenon known as Bolus Adhesion Residue (BAR)/), where minute particles of masticated material adhere to the dorsal epithelium, possibly promoting …
