Sense of Taste


Your sense of taste has more to it than you would expect.Taste is actually a combination of taste, smell, temperature, and touch. Your saliva dissolves your food so you can taste it. You have 4 main types of

taste buds. The 4 main types are sweet, salty, bitter, and sour are our main taste. All of our tastes are a combination of the 4 Different tastes. The front tip taste sweet and salty, the sides taste sour, the back taste bitter, and the middle taste nothing. Using all of that you are able to see if a food or drink. You can also see if the food or drink is good to eat. Now you know what taste actually is and what it can do to you.











Papillae

Papillae are bumps on your tongue and house taste buds. Papillae are the small little bumps on your tongue. These little bumps are what gives your tongue it rough feeling. The papillae are what house your taste buds. Each papillae holds 1 to 200 taste buds. The papillae are very important because they house and protect your taste buds.





Taste buds

Taste buds and chemosenses help you taste things. Taste buds are sensory receptors of taste. Taste buds are a group of cells that are on the papillae. You have 10,000 taste buds on your tongue. There are some taste buds on the roof of your mouth and the back of your throat. The Tongue also uses chemosenses that will respond to certain chemical substances. Each of your taste buds can have up to 50 chemical sensing cells that are clustered together. Your touch sensors in your mouth can detect hot and cold, pressure, hardness, and texture. As a cool fact, babies have a lot more taste buds than adults; they even have them on their cheek. Without taste buds your food would be bland.

Taste sensors and nerves

These are the nerves around the tongue (figure

Taste buds use your flavor sensing cells to detect tastes and send those tastes through nerves to the brains. The taste buds have special cells that send information to the brain about the food. When your taste buds detect certain taste it sends signals to the brain through nerves in your tongue. Your taste singles are sent to the taste center in your brain. Your body replaces your flavor sensing cells in your taste buds every ten years. When humans age the replacement of cells becomes less efficient so older people have less sense of taste. That’s how we know what we taste. tounge diagram 2.jpg
