[Greek stoma, stomat-, mouth.]
In medicine, stomatitis is inflammation of the mucous membrane of the mouth; stomatology is the study of the mouth and its diseases; and stomatogastric relates to the mouth and stomach. Stoma (plural stomas or stomata) is used in botany and zoology for various openings, such as the minute pores in the epidermis of the leaf or stem of a plant.
