Gustation Gustation is the action of tasting. Classified as a Chemoreceptor because it functions by reacting with molecular chemical compounds in a given substance. Specialized cells are taste buds. Influenced by genes, age, and experience.

Main types of tastes The five main types of taste sensation are bitter, salty, sweet, sour, and umami (Savory) Found through-out the entire mouth but most of the receptors are found on the tongue, also known as taste buds. Each taste bud is formed by two types of cells, supporting cells and gustatory cells. Spicy was originally thought as a taste but it comes from heat and pain receptors. Capsasin

Types of Taste Buds Fungiform papillae, which are mushrooms shaped and located at the tip of the tongue Foliate papillae, which are ridges and grooves toward the back of the tongue Circumvallate papillae, which are circular shaped and located in a row just in front of the end of the tongue. Filiform papillae, which are v shaped cones that do not contain taste buds. It is actually not a part of gustation.

Cranial Nerves V (trigeminal) chewing movements VII (facial) determines facial expression for the food you are eating and saliva secretion. IX (glossopharyngeal) taste and other sensations of the tongue X (vagus) swallowing XII (hypoglossal) tongue movement. Sense of taste is relayed to the Thalamus

Demonstration Hayley- sweet – tip of the tongue in the center (Chocolate) Hunter- savory [Umami] – throat, roof, and the back of the mouth. (chicken) Hannah- sour – sides of tongue (sour gummies) Spinda- salty – towards the tip on the sides (Chips) Shannon- bitter – back in the middle (Coffee)
