Detailed explanation-1: -The chemical substance responsible for the taste is freed in the mouth and comes into contact with a nerve cell. It activates the cell by changing specific proteins in the wall of the sensory cell. This change causes the sensory cell to transmit messenger substances, which in turn activate further nerve cells.
Detailed explanation-2: -The receptors for tastants are located across the outer portion and front of the tongue, outside of the middle area where the filiform papillae are most prominent. In humans, there are five primary tastes, and each taste has only one corresponding type of receptor.
Detailed explanation-3: -Food molecules (tastants) are dissolved in saliva, and they bind with and stimulate the receptors on the microvilli.
