The tongue and its taste buds

The tongue is a large muscle that is very sophisticated. It helps you eat and breathe as well as taste. Taste is broken down on the tongue in 4 places. the four tastes are sweet, sour, salt, and bitter. The are responsible for the taste of bitter things is on the back of your tongue. The taste of things that are sour are on the sides of your tongue. The taste of salty and sweet tends to be more towards the tip of your tongue. the taste buds are regenerated every 10-15 days. they are receptors for tastes to be sent to the brain. The signal comes from nerve endings to the 3 cranial nerves, then to the central nervous system to be changed into what we consider to be taste. Also, sight and smell are highly connected to your sense of taste.

  1. I think that this post is very interesting and i enjoyed learning about the four different sections of our tongue. It was also neat how our taste buds grow back but it stinks when i burn my tongue from something hot.
