The tongue is often regarded as the strongest muscle in the human body. However, this is a misconception as the tongue is not a single muscle but a group of eight muscles that intertwine with each other. The tongue is a powerful and hardworking muscle that helps in chewing, swallowing, speech, and producing saliva. It is constantly pushing saliva down the throat, even during sleep. The tongue is also flexible and can be twisted, bent, and moved in various directions. While it may not be the strongest muscle, it is definitely one of the most important and versatile organs in the human body.

What You'll Learn
The tongue is made up of eight muscles
The tongue is a muscular organ in the mouth of a typical tetrapod. It is made up of eight muscles, four of which are intrinsic, meaning they can change the tongue's shape and aren't attached to the bone. The other four are extrinsic muscles, which are anchored to the head and neck at the base of the skull, the bone in the throat, the lower jaw, and the lower palate. These extrinsic muscles enable us to move our tongues.
The four intrinsic muscles are the superior longitudinal, inferior longitudinal, transverse, and vertical muscles. They alter the shape of the tongue by lengthening and shortening it, curling and uncurling its apex and edges, and flattening and rounding its surface. They also have a role in facilitating speech, eating, and swallowing. The superior longitudinal muscle, for instance, shortens and widens the tongue, curling it upward. The transverse muscle, on the other hand, elongates and narrows the tongue.
The extrinsic muscles include the genioglossus, which protrudes the tongue, and the styloglossus, which retrudes the tongue and elevates its lateral margins. The hyoglossus muscle is responsible for retruding and depressing the tongue, while the palatoglossus elevates the posterior tongue, closes the oropharyngeal isthmus, and aids in swallowing.
The tongue is a versatile and hardworking muscle, essential for various tasks, including chewing, swallowing, tasting, and speaking. It is also involved in breathing and cleaning the teeth. Despite its strength and stamina, the tongue is not the strongest muscle in the body.

Four intrinsic muscles allow the tongue to change shape
The tongue is made up of eight different muscles, four intrinsic and four extrinsic. The four intrinsic muscles of the tongue are involved primarily in changing its shape and size, which is essential for speaking, eating and swallowing. These muscles are not attached to bone but only to other structures in the tongue. They are named based on the direction they travel—the superior longitudinal, inferior longitudinal, transverse and vertical muscles of the tongue.
The genioglossus muscle protrudes, depresses, and draws the tip of the tongue back and down. The hyoglossus depresses and retracts the tongue. The styloglossus retracts and elevates the tongue. The palatoglossus elevates the posterior portion of the tongue and is the only muscle innervated by the vagus nerve.
The tongue is not the strongest muscle in the body, but it is the hardest-working muscle. It is involved in digestion, taste perception, and speech, and it also plays an important role in breathing. Its strength may be due to its stamina in precision tasks like eating and speaking.

Four extrinsic muscles help the tongue move
The tongue is often regarded as the strongest muscle in the human body, and while this is a common misconception (the jaw muscle is actually stronger), the tongue's strength and dexterity are indeed remarkable. This is due to the presence of several types of muscles that allow for a wide range of movements and functions. Specifically, four extrinsic muscles play a key role in helping the tongue move with great flexibility and force.
The four extrinsic muscles of the tongue are the genioglossus, hyoglossus, styloglossus, and palatoglossus. Each of these muscles originates outside the tongue and attaches to it, enabling a variety of tongue movements that are essential for functions like speaking, chewing, and swallowing.
The genioglossus muscle is the largest and most anterior of the four extrinsic tongue muscles. It originates at the mental spine, which is located on the inner side of the lower jaw bone, and inserts into the tongue. The primary function of the genioglossus muscle is to protrude the tongue, allowing it to stick out and move forward. This muscle also helps in adjusting the position of the tongue during swallowing, ensuring that food goes down the esophagus instead of into the airway.
The hyoglossus muscle is located below the genioglossus and connects the tongue to the hyoid bone, a small U-shaped bone in the front of the neck. This muscle is responsible for depressing the tongue, pulling it downward, and helping to change its shape during speech and swallowing.
The styloglossus muscle originates from the styloid process, a small projection of bone in the temporal bone of the skull, and attaches to the sides and below the tongue. This muscle helps to elevate and retract the tongue, pulling it upward and backward. The styloglossus muscle works in conjunction with other muscles to create complex tongue movements during speech and swallowing.
Lastly, the palatoglossus muscle connects the tongue to the soft palate, or the back part of the roof of the mouth. This muscle helps to raise the back of the tongue and close off the throat during swallowing, preventing food or liquid from entering the nasal cavity. It also assists in closing the soft palate to separate the nasal cavity from the oral cavity during speech, enabling the production of certain sounds.
In summary, these four extrinsic muscles—genioglossus, hyoglossus, styloglossus, and palatoglossus—work in coordination to provide the tongue with an impressive range of motion and strength. This unique muscular arrangement allows the tongue to perform its vital functions with precision and agility, showcasing its importance in our daily lives.

The tongue is constantly working, even during sleep
The tongue is indeed one of the hardest-working muscles in the human body. It is made up of eight different muscles, four of which are intrinsic, allowing the tongue to change shape, and four extrinsic muscles that are anchored to the head and neck. The tongue is constantly working, even during sleep.
During sleep, the tongue plays a crucial role in maintaining normal breathing. The preBötzinger complex, a region in the brainstem, sends signals to the hypoglossal motor neurons, activating the tongue muscles and causing them to contract. This contraction keeps the tongue forward in the mouth, preventing the pharynx from narrowing and ensuring unobstructed breathing. This process is particularly important for individuals with obstructive sleep apnea, as their tongue muscles may not activate fully, leading to snoring and breathing difficulties.
The tongue also has a significant impact on our sleeping posture. It should ideally rest against the roof of the mouth, behind the front top teeth. This position helps signal the release of dopamine and serotonin. However, if the tongue is pulled back or strained, it can disrupt our airways and affect our sleep quality. Tongue exercises can help improve tongue posture, enhance breathing and digestion, and reduce neck and shoulder tension.
Additionally, the tongue is constantly pushing saliva down the throat, even during sleep. This function helps prevent the accumulation of saliva in the mouth, reducing the risk of choking or aspiration. Furthermore, the tongue contains lingual tonsils that filter out germs, providing a constant protective mechanism against harmful bacteria and viruses, even while we sleep.
While the tongue is not the strongest muscle in the body, its constant activity, versatility, and essential functions in speaking, chewing, swallowing, and breathing make it one of the hardest-working muscles.

The tongue is not the strongest muscle, but it is one of the hardest-working
The tongue is not the strongest muscle in the human body, but it is one of the hardest-working. The tongue is made up of eight different muscles, four of which are intrinsic, meaning they can change the shape of the tongue and are not attached to the bone. The other four are extrinsic muscles, anchored to the head and neck at the base of the skull, the bone in the throat, the lower jaw, and the lower palate. These muscles enable the tongue to move in all kinds of directions, allowing it to form sounds with the palate, teeth, and lips.
The tongue's versatility and stamina are impressive. It is responsible for a wide range of movements and functions, from eating and swallowing to speaking and tasting. Its strength and flexibility are essential for our daily lives, and it is constantly working throughout our lifetime.
So, if the tongue isn't the strongest muscle, which is? The answer depends on how we define "strongest." If we consider brute force, the gluteus maximus, or the butt muscle, is the largest and thus capable of generating significant force. The jaw muscle, or masseter, is also a contender due to the force it can exert during chewing.
However, if we consider overall work done, the heart is the hardest-working muscle, pumping at least 2,500 gallons of blood every day to keep our blood circulating. The tongue, while not the strongest, is undoubtedly a powerful and vital muscular organ that we would certainly be lost without!
