Fact or Fiction?: The Tongue Is the Strongest Muscle in the Body [1]
The tongue is an essential, often playful part of human anatomy. Many of us grew up believing the assertion that the tongue is the strongest muscle in the body
We asked a few tongue experts (yes they do exist) why the myth has been so easy to swallow.. Maureen Stone, of the University of Maryland School of Dentistry, speculates that the myth of the tongue’s strength arose from its amazing stamina even in precision tasks like eating and speaking
“If you don’t have any disorders, the answer is probably never.” Stone says the tongue’s tenacity springs from the way it is built—with lots of similar bits of muscle that can each perform the same task. “It doesn’t fatigue,” she says, “because there’s a lot of redundancy in the muscle architecture

Treasure Island (FL): StatPearls Publishing; 2022 Jan-.. The tongue is a muscular organ formed by a complex arrangement of intrinsic and extrinsic muscles
The tongue is principally involved in digestion, taste perception, and speech but also plays an important role in breathing.[1] It is attached via the extrinsic muscles to the hyoid bone, mandible, styloid process, soft palate, and pharynx and divided into two parts by the V-shaped sulcus terminalis. These two parts, an anterior two-thirds and a posterior one-third, are structurally and developmentally distinct
Acland’s Video Atlas of Human Anatomy [3]
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. Of these the two largest, which we’ll see now, are hyoglossus, and genioglossus
We’ll also remove all of the mucous membrane, from this line downwards.. Here are the hyoglossus, and genioglossus muscles, which together form the root of the tongue
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
Muscles and taste sensation of the tongue [4]
The tongue is a muscular organ situated in the oral cavity, and an accessory digestive organ. Its main functions include sensation of taste, mastication (chewing), deglutition (swallowing), speech, and clearing the oral cavity.
|Intrinsic muscles||Superior longitudinal, inferior longitudinal, transverse, and vertical muscles. |Extrinsic muscles||Genioglossus, hyoglossus, styloglossus, and palatoglossus
Receptors: taste buds within fungiform, vallate, and foliate papillae. Anterior two-thirds: chorda tympani (branch of facial nerve CN VII)
Wikipedia [5]
|Precursor||pharyngeal arches, lateral lingual swelling, tuberculum impar[1]|. |Artery||lingual, tonsillar branch, ascending pharyngeal|
Hypoglossal (XII), except palatoglossus muscle supplied by the pharyngeal plexus via vagus (X). The tongue is a muscular organ in the mouth of a typical tetrapod
The tongue’s upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels

How many muscles are in your tongue? [8]
The soft patty of flesh we call the tongue is not just one muscle, it’s a conglomeration of eight separate muscles. Unlike other muscles, such as the bicep, tongue muscles don’t develop around a supporting bone.

Tongue Muscle Anatomy: Architecture and Function [9]
– Maureen StoneMaureen StoneUniversity of Maryland School of Dentistry. The tongue is composed entirely of soft tissue: muscle, fat, and connective tissue
The lack of bones and cartilage means that muscle shortening creates deformations, particularly local deformations, as the tongue moves into and out of speech gestures. The tongue is also surrounded by the hard structures of the oral cavity, which both constrain its motion and support the rapid small deformations that create speech sounds
Tongue muscle volume indicates that four muscles, the genioglossus, verticalis, transversus, and superior longitudinal, occupy the bulk of the tongue. They also comprise a functional muscle grouping that can shorten the tongue in the x, y, and z directions
Intrinsic and extrinsic muscles of the tongue [10]
Did that title get you tongue-tied? ? You may have heard the common myth that the tongue is the strongest muscle in your body ?. It is made up of 8 different muscles that combine to form a flexible matrix similar to an elephant’s trunk ?
The tongue is composed of 2 main muscle groups these include:. These muscles only attach to other structures in the tongue
These muscles affect the shape and size of the tongue. They play a role in guiding our speech, eating, and swallowing ?
TeachMeAnatomy [11]
The tongue is a muscular structure located on the floor of the oral cavity.. It is the primary taste organ and plays a key role in the initial phases of swallowing.
The intrinsic muscles originate and attach to other structures within the tongue.. There are four paired intrinsic muscles of the tongue and they are named by the direction in which they travel – the superior longitudinal, inferior longitudinal, transverse and vertical muscles of the tongue
The motor innervation to the intrinsic muscles of the tongue is via the hypoglossal nerve (CN XII).. The extrinsic muscles of the tongue originate from structures outside the tongue and insert onto it.
Muscles and taste sensation of the tongue [12]
The tongue is a muscular organ situated in the oral cavity, and an accessory digestive organ. Its main functions include sensation of taste, mastication (chewing), deglutition (swallowing), speech, and clearing the oral cavity.
|Intrinsic muscles||Superior longitudinal, inferior longitudinal, transverse, and vertical muscles. |Extrinsic muscles||Genioglossus, hyoglossus, styloglossus, and palatoglossus
Receptors: taste buds within fungiform, vallate, and foliate papillae. Anterior two-thirds: chorda tympani (branch of facial nerve CN VII)
Anatomy and Physiology: The Terrific Tongue [13]
Here’s something fun you can tell people at parties: the tongue isn’t a single muscle—it’s a muscular hydrostat. What’s a muscular hydrostat, you ask? Essentially, it’s a strong, flexible biological structure that contains a whole bunch of muscle fibers but no skeletal structure
Anyway, because our tongues can bend, elongate, shorten, and twist so freely, they’re great for helping us swallow food and for producing an impressive inventory of unique speech sounds. They’re also the key to our sense of gustation (that is, taste).
The root of the tongue is connected to the hyoid bone via the hyoglossus and genioglossus muscles as well as the hyoglossal membrane. The body of the tongue contains both extrinsic and intrinsic muscles (more on those in a second)
Tongue Pictures, Anatomy & Diagram [14]
The tongue is unique in that it is the only muscle that isn’t connected to bone at both ends. It is connected on one end to the hyoid bone, which is also unique as it is the only bone not connected to any other bone in the body.
The tongue is made up of a number of individual muscles that aid in positioning it while chewing or speaking. The upper ‘skin’ surface of the tongue contains the taste buds
Taste buds cover the surface of small, nipple-like projections called, papillae, which are easily visible.. There are a number of problems that can develop with the tongue

Much of the surface of the tongue is covered in taste buds. The tongue, with its wide variety of possible movements, assists in forming the sounds of speech
The tongue is often cited as the “strongest muscle in the body,” a claim that does not correspond to any conventional definition of strength. For more on this subject, see Muscle: The strongest human muscle.
Your Tongue (for Kids) [16]
Want to find out just how much you use your tongue? Try eating an ice-cream cone or singing your favorite song without it. Has anyone ever told you that the tongue is a muscle? Well, that’s only partly true: The tongue is really made up of many groups of muscles
The front part of the tongue is very flexible and can move around a lot, working with the teeth to create different types of words. This part also helps you eat by helping to move food around your mouth while you chew
The muscles in the back of your tongue help you make certain sounds, like the letters “k” and hard “g” (like in the word “go”). Try saying these letters slowly, and you’ll feel how the back of your tongue moves against the top of your mouth to create the sounds.
Tongue: Definition, Location, Anatomy & Function [17]
Your tongue is a muscular organ in your mouth that aids in chewing, speaking and breathing.. A digestive organ, your tongue moves food around your mouth to help you chew and swallow
Your tongue helps keep your airway open so you can breathe properly, too.. Your tongue runs from your hyoid bone (located in the middle of your neck) to the floor of your mouth.
Your tongue is also covered with different types of papillae (bumps) and taste buds. You have four different types of taste buds, including:
Muscles in the Mouth, Explained [18]
Every day we eat, drink, and spend a few minutes thinking about our teeth as we brush and floss. It’s not often, though, that we spend much time thinking about the muscles in our mouth that allow us to chew, swallow, and speak
On the outside of your mouth, there are many facial muscles that form the cheeks and lips, and that assist in speech and facial expression. The orbicularis oris is the major muscle that immediately surrounds the mouth itself
– The masseter muscle is the main muscle used for chewing. It is the strongest muscle in the entire body, with the ability to close your jaws with anywhere from 55 to 200 lbs
Muscles of tongue [19]
The muscles of tongue can be divided into intrinsic and extrinsic groups.. The intrinsic muscles lie entirely within the tongue, while the extrinsic muscles attach the tongue to other structures.
Extrinsic tongue muscles, by definition, originate from structures outside the tongue and insert into the tongue. The four paired extrinsic muscles protrude, retract, depress, and elevate the tongue:
These muscles alter the shape of the tongue by: lengthening and shortening it, curling and uncurling its apex and edges, and flattening and rounding its surface:
The Tongue (Human Anatomy): Picture, Function, Definition, Problems, and More [20]
The tongue is covered with moist, pink tissue called mucosa. Tiny bumps called papillae give the tongue its rough texture
Taste buds are collections of nerve-like cells that connect to nerves running into the brain.. The tongue is anchored to the mouth by webs of tough tissue and mucosa
In the back of the mouth, the tongue is anchored into the hyoid bone. The tongue is vital for chewing and swallowing food, as well as for speech.
What is the strongest muscle in the human body? [21]
Question What is the strongest muscle in the human body?. There is no one answer for this question since there are different ways to measure strength
There are three types of muscles in the human body: cardiac, smooth and skeletal.. Cardiac muscle makes up the wall of the heart and is responsible for the forceful contraction of the heart
Skeletal muscles are attached to the bones and in some areas the skin (muscles in our face). Contraction of the skeletal muscles helps limbs and other body parts move.
