What do you call the taste receptors on your tongue?
Taste buds are sensory organs that are found on your tongue and allow you to experience tastes that are sweet, salty, sour, and bitter. Those are called papillae (say: puh-PILL-ee), and most of them contain taste buds. Taste buds have very sensitive microscopic hairs called microvilli (say: mye-kro-VILL-eye).
What are the 5 receptors on your tongue?
There are five specialized kinds of taste receptor proteins, and each kind detects particles with one of five basic tastes: sweet, sour, salty, bitter, and savory (the “meaty” aspect of foods such as soup broth).
What are the 4 main taste receptors?

Where are the taste receptors located on the tongue?
Taste buds appear at the apex of fungiform papillae on the anterior tongue and along trench walls of foliate and circumvallate papillae on the posterior tongue. Taste buds are also found on the soft palate and the epiglottis.
What are the three taste buds called?
In the surface of the tongue are raised bumps, called papilla, that contain the taste buds. There are three types of papilla, based on their appearance: vallate, foliate, and fungiform.
What is fungi form papillae?
Fungiform papilla: The fungiform papillae are broad flat structures that house taste buds in the central portion of the dorsum (back) of the tongue. These papillae were thought to resemble a fungus: a little mushroom. Fungiform means mushroom-shaped.
What is sweet taste receptor?
Sweet taste receptors are composed of a heterodimer of taste 1 receptor member 2 (T1R2) and taste 1 receptor member 3 (T1R3). These sweet taste receptors are heavily involved in nutrient sensing, monitoring changes in energy stores, and triggering metabolic and behavioral responses to maintain energy balance.
