3. Components

4. Tongue

5. In the back of the mouth, the tongue is anchored into
the hyoid bone. The tongue is a muscular organ in the
mouth. The tongue is covered with moist, pink tissue
called mucosa. The tongue is vital for chewing and
swallowing food, as well as for speech. 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. Because of this, all
parts of the tongue can detect these four common
tastes; the commonly described “taste map” of the
tongue doesn’t really exist. The four common tastes
are sweet, sour, bitter, and salty. A fifth taste,
called umami, results from tasting glutamate (present
in MSG).

6. • Typically a human tongue is around 3.3 inches (8.5 centimeters) for men
and 3.1 inches (7.9 cm) for women
• Most of the taste receptors are found on the tip of the tongue
• The root of the tongue is the bottom part of the tongue that can't be
seen.
• Sticking out your tongue is considered unacceptable behavior in many
cultures, but it is a sign of respect in others. In Tibet, sticking out the
tongue is a greeting.
• The sound that is produced from the voice box needs the help of the
tongue to make a word more audible and apprehensible.
• Tongue helps to keep the oral cavity clean. The food particles attached
to the teeth are cleared by tongue.
• Tongue helps to identify the thermal
nature of the food, whether it is hot
or cold.
• Women have a bigger number of taste
buds
• Taste buds are also located on the
roof of the mouth, and near the
pharynx
