Question

Quizplus · Accepted Answer

The diverse types of taste receptors are not evenly distributed across the tongue. While there is some variation among individuals, generally the sides of the tongue are more sensitive to sweet tastes, the back of the tongue is more sensitive to bitter tastes, the front of the tongue is more sensitive to salty tastes, and the middle of the tongue is more sensitive to sour tastes. However, it is also true that each taste receptor typically responds to multiple tastes, so option A is incorrect. Option B is incorrect because taste receptors are distributed all over the tongue, not just on distinct parts. Option C is also incorrect because taste receptors are not evenly distributed.
