Salivation
Salivation is the process in which the salivary glands in mammals produce saliva. Saliva is a fluid that aids in the initial process of digestion and helps in maintaining the health of the oral cavity.
Function[edit | edit source]
Salivation serves several purposes. It helps in the digestion of food by moistening it and breaking it down, aids in swallowing, and helps to keep the mouth clean. Saliva also contains enzymes that break down certain starches and fats, providing a chemical process of digestion.
Mechanism[edit | edit source]
The production of saliva is stimulated both by the autonomic nervous system and by the taste and smell of food. Nerve endings in the walls of the stomach also stimulate the salivary glands as part of a general reflex response to the presence of food. The salivary glands produce most of the saliva when food is in the mouth.
Disorders[edit | edit source]
There are several disorders that can affect salivation. These include Sjögren's syndrome, a condition that causes dry mouth and eyes, and salivary gland stones, which can block the flow of saliva. Other conditions, such as Parkinson's disease and depression, can also affect salivation.
