Abstract
1. The sensory nerve endings of the adult human hard and soft palates and of the uvula have been described. They consist of free nerve endings within the epithelium, of numerous organized endings mainly in the dermal papillæ, and of a few organized endings in the subpapillary region of the dermis.2. The organized endings of the hard and soft palates show a general similarity in morphological character, but are more numerous in the former, where they also show “ultra‐terminal” fibrils penetrating the epithelium. Those in the uvula are of one type, show no “ultraterminal” fibrils and exhibit fine beading in their component fibrils.3. Most of the organized endings are of unnamed form. Typical Meissner corpuscles are infrequent, while Krause end‐bulbs are relatively uncommon. Accessory fibres are found associated with all these types. No Pacinian corpuscles or endings of Ruffini or Golgi‐Mazzoni types have been seen.4. An autonomic ground plexus is present in the dermis of palate and uvula.5. No taste buds have been found.
