Answer 2

"Yes salivation is a reflex action that is controlled by the activation of the autonomic nervous system response to the oral cavity. The saliva is a sudden gush of bicarbonate ions to standardize or regulate the sour taste or acidic pH that is sensed by the taste buds.

It is well explained by Pavlov’s theory where the bell of the door serves as a stimulus for the unconditioned salvation response to occur."
