What can the human tongue detect?
When food enters the mouth, small molecules of the food can be sensed by the tongue. We know that different foods have different tastes. We can sense five different tastes—sweet, bitter, sour, salty, and savory. Taste receptors are found on the upper surface of special cells called taste cells.
What are two things your tongue can detect?
Today we know that different regions of the tongue can detect sweet, sour, bitter and salty. Taste buds are found elsewhere too – in the roof of the mouth and even in the throat.
What senses does the tongue have?

What does the tongue respond to?

What are the functions of the tongue?
The tongue (L. lingua; G. glossa) functions as a digestive organ by facilitating the movement of food during mastication and assisting swallowing. Other important functions include speech and taste.
What are the five taste sensations that the tongue can recognize?
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.
How does our tongue Recognise taste?
Taste buds have very sensitive microscopic hairs called microvilli (say: mye-kro-VILL-eye). Those tiny hairs send messages to the brain about how something tastes, so you know if it’s sweet, sour, bitter, or salty. The average person has about 10,000 taste buds and they’re replaced every 2 weeks or so.

Normal Tongue Color and Texture. The tongue is naturally pink to red in color with a rough appearance. The color is due to the blood flow within it while the roughness is due to tiny bumps known as papillae (singular ~ papilla).
What is the anatomy of the tongue?
The anatomy of the tongue consists of a series of eight muscles, with a covering of mucous membrane and small bumps known as papillae. It is connected to the mouth by the frenulum, a thinly-layered stretch of tissue that prevents the tongue from being swallowed.
What is a human tongue?
The human tongue is a muscular organ that is covered by a thin mucous membrane. It lies partly in the mouth cavity and partly in the oropharynx. It is highly mobile and can be shifted into a number of different positions and also assume various shapes.
