The mouth is the only place in the body which provides the sensation of taste. Due to these unique physiological features, the oral mucosa must fulfil a number of distinct functions. Protection: One of the main functions of the oral mucosa is to physically protect the underlying tissues from the mechanical forces, microbes and toxins in the ...
Mucin genes encode mucin monomers that are synthesized as rod-shaped apomucin cores that are post-translationally modified by exceptionally abundant glycosylation. The dense "sugar coating" of mucins gives them considerable water-holding capacity and also makes them resistant to proteolysis , which may be important in maintaining mucosal barriers.
Digestion: Saliva contains amylase, which hydrolyses starch into glucose, maltose, and dextrin. As a result, saliva allows some digestion to occur before the food reaches the stomach. [30] Taste: [31] Saliva acts as a solvent in which solid particles can dissolve and enter the taste buds through oral mucosa located on the tongue. These taste ...
The function of the salivary glands is to secrete saliva, which has a lubricating function, which protects the mucosa of the mouth during eating and speaking. [2] Saliva also contains digestive enzymes (e.g. salivary amylase), has antimicrobial action, and acts as a buffer. [3]
Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
It causes inflammation and discomfort by affecting the throat and tonsils, "which are the lymph nodes in the back of your mouth," says Dr. Jason Nagata, a pediatrician at UCSF Benioff Children’s ...

One of its functions is to keep the tissue moist (for example in the respiratory tract, including the mouth and nose). [ 2 ] : 480 It also plays a role in absorbing and transforming nutrients . [ 2 ] : 5, 813 Mucous membranes also protect the body from itself.
