Tongue what kind of muscle




















But what, then, is the strongest muscle system in the body? There are lots of ways to measure strength. One is brute force, in which case biggest is best. All skeletal muscles are bundles of many individual fibers that contain small force generating structures called sarcomeres.

That means the largest muscles—the quadriceps on the front of your thighs and the gluteus maximus on your rear—produce the most force. Muscles work by pulling on bones, which act as levers that convert muscular contractions small but powerful movements into large motions—think: curling a dumbbell. Your bicep pulls on the bones in your forearm to lift the dumbbell. Because your forearm is long and the bicep pulls on it right near the elbow, says Khalil Iskarous, a linguist at the University of Southern California, the bicep has to pull with a lot of force to move your hand up to your shoulder.

Your jawbone, in contrast, is a much shorter lever. Because of this, the masseter, the main muscle in your jaw, is also a contender for strongest muscle in the body. The tongue may not be as strong as the glutes, jaw or heart but strengthening it may still be useful. Tasko says there is some evidence suggesting that strengthening exercises may benefit people who have trouble swallowing, such as those recovering from stroke. Some speculate that strengthening the tongue may even improve speaking abilities or help treat speech pathologies.

Tasko warns, however, that these assertions are controversial and need further testing. Julia Calderone is a freelance science writer based in New York City. Rough textures of the tongues of these species helps them to use their tongues to remove oils and parasites by licking themselves and each other.

Aside from daily uses for eating and drinking, a dog's tongue acts as a heat regulator. As a dog increases its exercise the tongue will increase in size due to greater blood flow. The tongue hangs out of the dog's mouth and the moisture on the tongue will cool down further cooling down the bloodflow. Some animals have prehensile tongues.

For example, chameleons, frogs, salamanders and some species of fish use their tongues to catch prey. Many insects have a type of tongue called a proboscis that is used for the same purpose or, in the case of butterflies, to drink nectar [3]. The corresponding organ in ants is called the hypopharynx [4]. Molluscs have a rough tongue called a radula [5], which they use to grind food.

Tongue rolling is the act of rolling the tongue axially into a tube shape. The ability to roll the tongue has been generally believed to depend on genetic inheritance. Tongue rolling was believed to be a dominant trait with simple Mendelian inheritance , and is still commonly used as an example in high school and introductory biology courses.

It provided a simple experiment to demonstrate inheritance. There is little laboratory evidence, though, for the common belief that tongue rolling is inheritable and dominant. A twin study found that identical twins who share all of their genes were no more likely than fraternal twins who share an average of half to both have the same phenotype for tongue rolling.

The tongues of some animals are consumed and sometimes considered delicacies. In America and the United Kingdom, cow tongues are among the more common. Hot tongue sandwiches are frequently found on menus in Kosher delicatessens and in America.

In the United Kingdom tongue can often be found at the local grocer, where it is often sold in reformed slices of meat after being ground up and set in gelatine. Taco de lengua lengua being Spanish for tongue is a taco filled with beef tongue, and is especially popular in Mexican cuisine. Tongue can also be prepared as birria.

Duck tongues are sometimes employed in Szechuan dishes, while lamb's tongue is occasionally employed in Continental and contemporary American cooking. Fried cod tongue is a relatively common part of fish meals in Norway and Newfoundland. Tongues are also used in sausage making. Historically, buffalo tongue was once considered an especially exquisite dish, and is one of the reasons for the American Bison being hunted by humans to the point of near extinction.

The muscles that form the bulk of the tongue are intrinsic muscles, which run from one part of the tongue to another, and extrinsic muscles, which are attached to bone.

There are three extrinsic muscles on each side. Here are the hyoglossus, and genioglossus muscles, which together form the root of the tongue. All this is genioglossus. Genioglossus arises just above the genio-hyoid, from the upper part of the mental spine.

Its fibers fan out, the highest ones arching forward almost to the tip of the tongue, the lowest ones running straight backward to the most posterior part of the tongue. Genioglossus compacts the tongue, and pulls it forwards.

Hyoglossus is a thin, flat sheet of muscle. Its fibers run upwards and forwards. Hyoglossus flattens the tongue, and pulls it backwards and downwards.
