PATHOLOGY

Detailed explanation-1: -Sweet, sour, salty, bitter and savory tastes can actually be sensed by all parts of the tongue. Only the sides of the tongue are more sensitive than the middle overall. This is true of all tastes – with one exception: the back of our tongue is very sensitive to bitter tastes.

Detailed explanation-2: -5 basic tastes-sweet, sour, salty, bitter, and umami-are messages that tell us something about what we put into our mouth, so we can decide whether it should be eaten.

Detailed explanation-3: -Viewed under a microscope, your tongue is an alien landscape, studded by fringed and bumpy buds that sense five basic tastes: salty, sour, sweet, bitter, and umami. But mammalian taste buds may have an additional sixth sense-for water, a new study suggests.
