Taste is detected by sensory receptors (chemoreceptors) in our taste buds, which cover the tongue but are also found in the soft palate of the mouth and the throat.
The cranial nerves associated with taste are the glossopharyngeal (VII), facial (IX) and vagus (X) nerves. When the receptors in the taste buds are stimulated by food, impulses are sent along these nerves to the part of the brain where taste is perceived (in the parietal lobe)
The area of the tongue which is thought to be most sensitive to sweet tastes is the tip.
Taste buds on the tongue contain receptors that are sensitive to sweet molecules. When these molecules come into contact with the taste buds, they bind to the receptors, sending signals to the brain that are interpreted as sweetness.
Scientists describe five basic tastes: bitter, salty, sour, sweet, and umami that the tongue can detect, some people believe that there are areas of the tongue that detect these tastes - (the front tip of the human tongue for salty and sweet, the sides for sour things and the back of the tongue for bitter things). However many scientists now believe that the taste buds over the whole tongue are all involved.
It is important to note that the while the tongue is involve in the taste of things it is actually the scene of smell at the back of the nose that is the best detector for the more complete taste of the foods we eat. You can prove this by holding you nose while eating - food seems to have no taste when you do this.
There is no specific part of the tongue dedicated to any particular taste (sweet, sour, bitter, etc). There are various tastebuds tuned to the specific tastes, however these are scattered randomly across the tongue.

Where does your tongue generally detect sweet tastes?
Sweetness was previously believed to reside only at the tip, however newer research shows that taste occurs for all five sensations over the entire surface of the tongue.
Why would a tongue not detect mild sweetness after eating foods with high sweetness?
After consuming high levels of sweetness, taste buds can become desensitized, leading to a reduced ability to detect mild sweetness. This phenomenon is known as sensory adaptation. Sensory adaptation occurs when taste receptors become less responsive to a constant stimulus, causing decreased sensitivity to that taste.
Which taste sensations could be lost after damage to the facial nerve?
Loss of taste sensations that could result from damage to the facial nerve include the inability to taste sweetness on the anterior two-thirds of the tongue due to dysfunction of the chorda tympani branch of the facial nerve, which carries taste information. This can lead to a reduced ability to detect sweet flavors on that part of the tongue.
Is your tongue more sensitive to salty taste or sweet?
The human tongue is more sensitive to sweet tastes than salty tastes. This sensitivity is due to the presence of taste buds that are specialized for detecting sweetness.
What body part can recognize four basic kinds of taste sweet salty sour and bitter?
The tongue is the body part that can recognize the four basic tastes of sweet, salty, sour, and bitter. Taste buds located on the tongue detect these tastes, which are then sent to the brain for interpretation.
Where does your tongue generally detect sweet tastes?
Sweetness was previously believed to reside only at the tip, however newer research shows that taste occurs for all five sensations over the entire surface of the tongue.
Can the tongue detect pressure?
Yes, the tongue can detect pressure.
What basic tastes can the tongue detect?
The four basic tastes are bitter tastes, sweet/sugary tastes, salty tastes and sour tastesSweet, Salty, Sour and Bitter.
If sweetness is detected by the presence of glucose what does sourness detect?
Sourness is detected by the presence of hydrogen ions (H+), which impart acidity to a substance. When acidic compounds are present in food, they stimulate taste receptors on the tongue, signaling sourness to the brain.
Why would a tongue not detect mild sweetness after eating foods with high sweetness?
After consuming high levels of sweetness, taste buds can become desensitized, leading to a reduced ability to detect mild sweetness. This phenomenon is known as sensory adaptation.

Where are the bitter taste buds located?
The area of the tongue that controls the taste and sensation of bitterness is located primarily in the back of the tongue, close to the uvula and going back towards the throat. The area of the tongue that controls the taste of sourness is located in the lateral-back of the tongue. The area that controls the sensation of saltiness is located on the lateral front of the tongue, and the part of the tongue that controls the sensation of sweetness is on the tip of the tongue.
What five basic tastes can your tongue detect?
Bitterness, saltiness, sourness, and umami are the five basic tastes that our tounge's detect.
Is your tongue more sensitive to salty taste or sweet?
The human tongue is more sensitive to sweet tastes than salty tastes. This sensitivity is due to the presence of taste buds that are specialized for detecting sweetness.

What detects odor with the tongue?
The olfactory receptors in the nose detect odors, not the tongue. The tongue is responsible for detecting tastes through taste buds, which are sensitive to sweet, salty, bitter, sour, and umami flavors.
Taste receptors?
Cells on the tongue that detect and respond to different flavors, allowing for the sense of taste.
