ANATOMY

Detailed explanation-1: -The tongue is a sensory organ which helps in the perception of the sense of taste. The various nerves which supply the tongue include the trigeminal nerve (V), the facial nerve (VII), the glossopharyngeal nerve (IX) and the vagus nerve (X).

Detailed explanation-2: -The tongue has many nerves that help detect and transmit taste signals to the brain. Because of this, all parts of the tongue can detect these four common tastes; the commonly described “taste map” of the tongue doesn’t really exist.

Detailed explanation-3: -An important function of the tongue is taste sensation, which is derived from taste receptor cells located in clusters within taste buds on the surface of the tongue. In humans there may be anywhere from 50 to 150 taste receptor cells within an individual taste bud.

Detailed explanation-4: -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.
