Abstract
The development of sensory nerve fibres in the. mucous membrane of the oral cavity base is very weak, in parallel with the poor formation of epithelium and papillae in this region, most of the papillae lacking sensory fibres penetrating them. In cases when the papillae are provided with sensory fibres, their terminal formation is generally very simple, being represented by unbranched terminations showing a simple course. But in some cases, the terminations are branched, though simple, and in rarer cases, very simple glomerular terminations are also observed.
In the mucous membrane of the oral cavity base, some few taste-buds can be found, though very rarely. They are formed in the thinned out epithelium, which caused by the papilla sticking into the epithelium. The sensory fibres to the taste-buds are often rather well-developed and sometimes form complex branched termination, especially glomerular termination, but since no fibres are found running into the taste-buds or around them, their functional capacity must be deemed to be of degenerated inadequacy.
