salivarysalivary[sal´ĭ-ver-e]The saliva is needed to moisten the mouth, lubricate food for easier swallowing, remineralize the tooth surface, and provide the enzyme (ptyalin) necessary to begin food breakdown in the preliminary stage of digestion. The salivary glands produce about 1.5 liters of saliva daily. The salivary glands are controlled by the nervous system. Normally they respond by producing saliva within 2 or 3 seconds after being stimulated by the sight, smell, or taste of food. This quick response is a reflex action. In mumps (parotitis), the parotids become inflamed and swollen. Occasionally, salivary glands produce too much saliva; this condition is called ptyalism, and is the result of local irritation from dental appliances or of disturbances of digestion or of the nervous system or other causes. Certain diseases, drugs such as morphine or atropine, and nutritional deficiency of vitamin B can result in decreased secretion of saliva. sal·i·var·y(sal'i-vār'ē),salivary(săl′ə-vĕr′ē)salivaryadjective Relating to the saliva or salivary gland.sal·i·var·y(sal'i-var-ē)Synonym(s): sialic, sialine. sal·i·var·y(sal'i-var-ē)Synonym(s): sialic, sialine. |
