Unique Anatomy of the Tongue

Every tongue is very unique, not unlike fingerprints. Currently there are researchers working on reliable ways to use the tongue as a biometric authentication to identify an individual. It is amazing!

The tongue has 2,000 to 10,000 taste buds. Contrary to current belief there are no places on the tongue where taste buds are specific to just sweets, salt or tart flavors. Taste buds exist in the epiglottis and the back of the throat also. The tongue has small, pinkish-white bumps, called papillae, that are actually very fine hairlike projections. The papillae can be seen on the above picture.

On average the taste buds die off and are then replaced every 10 to 14 days.There are some people with more than 10,000 taste buds, and they are known as supertasters. Children and infants have more taste buds than adults, with some taste buds even in their cheeks and lips. This may explain why they can be so picky about food.

The tongue is very flexible, and it has eight intertwining muscles that create this flexibility. The tongue muscles are the only muscles in the body that are totally independent of the skeleton.

The tongue is separated by a length of vertical fibrous tissue. The muscles in the tongue enable shaping the tongue to facilitate eating, swallowing and talking. The tongue muscles never get tired.

Average Length of the Tongue

The average tongue for an adult male is 3.3 inches long, and a female tongue averages 3.1 inches. However, Nick Stoeberl has a tongue of approximately 3.9 inches, and he is in the Guiness Book of World Records. Enjoy the short video below if you want to see the longest tongue on record.

Signs of an Unhealthy Tongue

The healthy tongue is a pink shade, but if it is smoother than a normal tongue you may have a deficiency of nutrients, such as vitamin B12, iron or folic acid. A very red tongue may indicate a sore and/or fever.

If the tongue has white patches, which may also be on the inside of the mouth, that typically means you have thrush. Thrush (a fungal infection) is easily treated, but you need a prescription from your doctor.

The University of Pennsylvania completed of study of people with obstructive sleep apnea, and they found obese individuals had a larger tongue, which had more fat.

A yellow tongue usually indicates some type of stomach problem. You may have pain or a burning sensation on you tongue, and spicy or acidic food is typically the cause.

Approximately 75% of the cancers are due to modifiable behaviors, such as excessive alcohol consumption or some type of tobacco use.

What About Other Mammals?

Dogs and cats are mammals that use their tongue in a number of ways. One way is to clean their fur or body. Their tongue tends to have a rough texture, which aids them in removing parasites and oils as well.

A dog’s tongue acts as a heat regulator. You will see a dog’s tongue hanging out of his or her mouth. The reason is the moisture on the tongue helps to cool the blood flow.

Fish, reptiles, birds and amphibians all have tongues, but alligators, crocodiles and gharials do not have tongues. Of course, that last group sure have plenty of teeth.

Summary

The tongue's many unique features are interesting. It is good to be aware of the possible problems that may occur, so take a look at it when you brush your teeth. Dentist encourage people to brush their tongue also to get rid of any bacteria, and this should be done twice daily.

Hi Pamela, I never thought so much about the tongue before. Very interesting, though. I never knew that children and infants have more taste buds and that taste buds die and get replaced. Now if my or someone in my family has a different color on their tongue I can refer to your hub. Thanks for sharing this information.

Have a blessed Thanksgiving.

Hi Shauna, I think a lot of people just weren't taught as children, Yet I would imagine a dentist would tell a patient that brushing the tongue was important.

Thanks for your comments.

I always brush my tongue when I brush my teeth. When my ex-husband saw me doing that, he asked me what I was doing and why. Self-explanatory, isn't it? He started brushing his tongue after seeing me do it. How can someone go their entire life without brushing their tongue? Gross!
