The average human tongue is 4 inches long. The average giraffe 's tongue is 21 inches long! The human tongue is mainly made up of skeletal muscle with over 10,000 taste buds on the surface.
The tongue is a muscular organ in the mouth. The tongue is covered with moist, pink tissue called mucosa. Tiny bumps called papillae give the tongue its rough texture. Thousands of taste buds cover the surfaces of the papillae. Taste buds are collections of nerve-like cells that connect to nerves running into the brain.
It is part of the gastrointestinal (digestive) system. The tongue helps you to swallow, then peristaltic action propels food, now called a bolus, down the esophagus.
PARTS OF TONGUE There are five parts of the tongue and their names and functions are as follows:
The Papillae is situated on the upper side of the tongue and marked by its granular projection . There are four types of papillae on the tongue : Filiform, fungiform, foliate, and vallate. The papillae are where the taste buds are. They help us identify different tastes of food. The food comes in contact with the taste buds when the saliva breaks it down allowing the microvilli to carry a message to the brain regarding the taste.
The tonsils filter germs. There are two types of tonsils: Lingual and palatine. Both help with filtering germs.
Adenoids help fight infection . These can swell up when a person is sick making it hard to breathe , but they also help to fight the disease .
The Frenulum linguae secure the tongue in place. It is the underside of the tongue that connects the tongue to the bottom part of the jaw. It is a thin strip of skin and muscle.
The sulcus terminalis is the median of the tongue . It is what divides the tongue into two halves. It is about 2.5 centimeters from the root. It runs laterally and forward on either side of the margin of the tongue .
The tongue is where we will find our taste buds and it helps us chew. The mechanism does need to be cleaned in order to keep the mouth and the teeth clean
