Soft palate

Definition and stakes

Joseph C. Hutchison,  A Treatise on Physiology and Hygiene

“ The soft palate, also, possesses the sense of taste; hence, an article that has an agreeable flavor may very properly be spoken of as palatable, as is often done. All parts of the tongue do not perceive equally well the same flavors. Thus, the front extremity and margin, which is the portion supplied by the "fifth pair" of nerves, perceives more acutely sweet and sour tastes; but the base of the tongue, supplied by the glosso-pharyngeal nerve, is especially sensitive to salt and bitter substances. ”

Portrait of John Gray McKendrick John Gray McKendrick,  Encyclopædia Britannica, Ninth Edition (1888)

“ The posterior part of its surface, where there is a Λ-shaped group of large papillæ, called circumvallate papillæ, supplied by the glosso-pharyngeal nerve, and the tip and margins of the tongue, covered with filiform (touch) papillæ and fungiform papillæ, are the chief localities where taste is manifested, but it also exists in the glosso-palatine arch and the lateral part of the soft palate. The middle of the tongue and the surface of the hard palate are devoid of taste. ”
