The oral mucosal membrane and transient receptor potential channels.

The oral cavity is the first line of defense, sensation, and secretion of the alimentary canal. Oral perception contributes to the enjoyment of food and beverages and to avoiding consumption of poisonous or harmful substances. Oral sensation is served by somatosensory nervous systems distributed to the oral membrane. Recent studies reported that oral epithelial cells may transduce temperature and touch through membranous sensors, which comprise ion channels with multimodal properties, and nerves. Here, we describe the possible role of oral epithelial cells in oral perception.
