HUMAN NUTRITION

Detailed explanation-1: -Answer. Explanation: When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste.

Detailed explanation-2: -Salivary secretion is controlled by the autonomic nervous system, and occurs in response to stimulation by neurotransmitters released from nerve endings [1, 2]. Simulated parasympathetic neurons primarily release acetylcholine, which binds to muscarinic cholinergic receptors in the acinar cells of salivary glands.

Detailed explanation-3: -Taste processing is first achieved at the level of taste receptor cells (TRCs) which are clustered in taste buds on the tongue. When TRCs are activated by specific tastants, they transmit information via sensory afferent fibers to specific areas in the brain that are involved in taste perception.

Detailed explanation-4: -Classical Neurotransmitter Receptors Muscarinic-Cholinergic Receptors These receptors are quite abundant in salivary cells (table 1) and, as noted above, appear to mediate the primary fluid secretory response (parasympa-thetic) from salivary glands in mammals.
