MICROANATOMY

Detailed explanation-1: -Its main role includes transport of taste substances to and protection of the taste receptor. In the initial process of taste perception, saliva acts as a solvent for taste substances; salivary water dissolves taste substances, and the latter diffuse to the taste receptor sites.

Detailed explanation-2: -Saliva has modulating effects on sour, salt, and the monosodium-glutamate-induced savory or umami taste. It has a diminishing effect on sour taste as a result of the buffering by salivary bicarbonate. It probably also contributes to the umami taste with endogenous salivary glutamate levels.

Detailed explanation-3: -The facial nerve or 7th cranial nerve is known as a “cranial nerve” since it starts in the brain. It sends branches out to the face, neck, tongue, salivary glands (secrete saliva into the mouth), and the outer ear.

Detailed explanation-4: -Gustatory-salivary reflex. Masticatory-salivary reflex. Olfactory-salivary reflex. Visual and psychic salivary reflexes. 05-Jan-2015
