Strong human muscles

The strength of a person's muscles is determined by what load he can lift.
The working qualities of a muscle are associated with its ability to suddenly change its elasticity.
Becoming elastic, the muscle holds the load, this is where muscle strength is manifested.
A human muscle develops a force of up to 156.8 N for every square centimeter of section.

The strongest muscle in the human body

The strongest muscle in terms of force generated in the human body is considered chewing muscle, on the molars of a person, which develops a force of up to 72 kg and is located in the back of the jaw.
The chewing muscle is part of a group of muscles that provide movement of the lower jaw during chewing.

The chewing muscle, in addition to chewing movements, takes part, together with the facial muscles, in the articulation of speech, facial expressions and yawning.
Some muscles of the neck are also involved in chewing:

• chin-hyoid,
• maxillofacial,
• digastric.

Thanks to the chewing muscles, the chewing process is carried out as a result of the displacement of the lower jaw during their contraction.

The strongest muscle in man

chewing muscle raises the lower jaw.
It has the shape of an irregular rectangle and consists of a superficial part and a deep part.
The starting point of the superficial part is the anterior and middle sections of the zygomatic arch, and the deep part is the middle and posterior sections of the zygomatic arch.
Both parts of the muscle are attached on the lateral side of the lower jaw branch along its entire length and to the angle of the jaw.

temporalis muscle raises the lower jaw, while the posterior muscle bundles take it back, and the anterior - forward and upward.
The muscle begins on the temporal surface of the greater wing of the sphenoid bone and the squamous part of the temporal bone, and is attached to the apex and medial surface of the coronoid process of the mandible.

Lateral pterygoid muscle performs two functions: with bilateral contraction (simultaneous contraction of both muscles), it pushes the lower jaw forward, and with unilateral contraction, it shifts it to the side, in the opposite direction (in the direction opposite to the contracting muscle).
It is located in the lower temporal fossa, the beginning is the temporal surface of the large wing of the sphenoid bone, the lateral plate of the pterygoid process and the infratemporal crest, and the attachment site is the medial surface of the articular capsule of the temporomandibular joint, the articular process of the mandible and the articular disc.

medial pterygoid muscle, as well as the lateral one, with a bilateral contraction pushes the lower jaw forward, simultaneously raising it, and with a unilateral contraction it shifts in the opposite direction. The muscle begins in the pterygoid fossa of the sphenoid bone and is attached to inner surface lower jaw.

The strongest muscle in the human body

Strongest tensile muscle- This is the calf muscle, it is able to hold a weight of 130 kg.
Every healthy person is able to "stand on tiptoe" on one leg and even lift an additional load. This burden is mainly calf muscle.

The calf muscle is biceps on the back of the human leg.
It is located above the soleus muscle, together with which it is attached to the heel through the thick Achilles tendon. Functional activities include primarily the movement of the foot in the sagittal plane and the stabilization of the body during movement (walking and running).

Come visit us, we are interested! :-)

Our body is a complex device. It consists of the smallest cells from which bones, skin, internal organs and tissues, blood and, of course, muscles are built. Muscles perform important functions - they help us move, speak, breathe, see, and they are also help internal organs. In other words, everything that is set in motion in our body, in particular, the most important - blood supply and respiration, is carried out with the help of muscles.

In total, there are a huge number of muscles in our body - up to 850 (counting methods are different). When thinking about what function this or that muscle performs, sometimes you wonder - which of them is the strongest? Most likely - the largest - the biceps of the thigh, for example, or the quadriceps, or the back muscles, which are very wide and often voluminous ... But if you look at the answer to the question which the strongest muscle in the human body- from the point of view of medicine, for many it will be somewhat unexpected. It's pretty hard to figure this out on your own.

In general, the largest in our body are buttock muscles, and the smallest ones are attached to small bones that are located in the ear. How is the strength of a muscle determined? Naturally, the way she can lift weight. Those muscles that are located outside the body can lift weight much more than those that are inside it.

So the list of the most strong muscles in the human body

• by what force is created - chewing muscle;
• by the force that is applied to the point of its attachment to the skeleton - this quadriceps in the thigh (large gluteus);
• according to the force that is applied for stretching - the calf muscle;
• in terms of endurance, the heart muscle leads (it works all 24 hours a day).

Thus, the strongest muscle in the truest sense of the word, i.e. according to the level of effort, is the masticatory muscle. But if you do not know about it in advance, it is quite difficult to guess about this fact.

Many people ask the question, what is the strongest muscle in the human body? It is known that their number reaches 640. Among them there are very small ones that are in the inner ear or serve to fix the eyeball. There are also quite large muscles: quadriceps, gluteus, trapezius. However, the most unique can be called the myocardium. It is able to contract even if it is removed from the human body. So which muscle is the strongest?

Enough precise definition provide special studies. According to them, the strength of all muscles depends on the following factors:

quantities muscle fibers;

The size of the bone adjacent to the muscle;

attachment angle;

The frequencies of the pulses that it creates nervous system.

To characterize this parameter, special terms have been created: relative and absolute. Also, this indicator is determined in accordance with the amount of cargo that a person is able to lift in a calm state.

The quality of muscle work is determined by the ability to change their elasticity. With contraction, this figure increases, with relaxation, it becomes much lower. Therefore, many say that the strongest human muscle is the tongue. However, this judgment is incorrect, since it is an organ consisting of 16 muscle parts.

The force generated is also an important parameter. It turns out that the strongest human muscle is chewing. It can develop a pressure force of up to 72 kilograms and is located near It is she who makes you move in the process of chewing. Accordingly, she got her name. A feature of the location is attachment to the bone. There are other muscles that perform a similar function. These include: temporal, lateral and medial pterygoid. The first starts from a simultaneous bone. The lateral pterygoid is fixed on the inner corner of the lower jaw, the medial - on the articular process. Also, the masticatory muscle interacts with other formations of a similar structure during conversation, facial expressions and yawning. Its shape resembles an irregular triangle.

Another factor by which the strongest human muscle is determined is the tensile strength. According to this factor, the calf muscle is in the lead, which is able to hold weight up to 130 kilograms. To confirm this, you need to rise "on tiptoe" and pick up a small weight. In this case, the entire load will fall on the calf muscle. It is located in the back of the leg. Next to it is the soleus muscle, with which they are attached to the heel with the help of the Achilles tendon. It has a simple structure (two heads), but in terms of muscle tissue density it occupies a leading position in the human body. Its function is to stabilize the body during movement.

Another indicator that helps to determine the strongest muscle of the human body is the force that is applied to the point of the skeleton. According to this indicator, one can distinguish four-headed and gluteal muscle. They are also found on the lower extremities. In addition, the most big muscle human - gluteal. All this is confirmed by its functions, the main of which is to maintain the position of the body in vertical position.

Thus, the strongest human muscle is an ambiguous concept. Each of them dominates according to a certain indicator. But the real leader can be called which has the highest rate of endurance. While other structures are subject to fatigue, it works flawlessly even during sleep. Yes, and the term of myocardial work can be called more than a weighty argument that casts doubt on the fact of greater efficiency

What is the strongest muscle in human body? Some people say that these are our buttocks. Others believe that it is the jaw. Still others are sure that this is our language. The muscle that wins this battle depends on your definition of the word "strongest", but you can definitely tell which one is losing. The tongue is not the strongest muscle in the human body. To begin with, this is not even one muscle, but a whole group.

Not everyone will be able to pronounce this tongue twister "Buy a bale of peak, buy a bale of fluff"

The tongue can be perceived as one huge muscle, but in fact it is a group of muscles. And while the vast majority of the muscles in your body are attached to bones, many of the muscles in your tongue are simply attached to each other. They form the so-called muscular hydrostat, the same as the leg of an octopus or the trunk of an elephant.

The four muscles of the tongue that are not attached to anything are called internal. Each of them moves freely in different directions, which helps your tongue perform such impressive gymnastics as, for example, curling up into a tube or licking your gums. Four more muscles attach it to the head: one - to the base of the skull, the second - to the throat, the third - to the lower jaw, and the fourth stretches to the sky. Each of these muscles is bilateral, which means they are partly separated by a central line that helps them work on both sides of your mouth.

Muscle battle

Now you know that the tongue is not one muscle, but a whole system. But is it the strongest in the body? You can actually measure your tongue strength or at least your endurance with the Iowa oral performance instrument. All you have to do is stick a straw into your mouth, on the tip of which there is a small plate, and press it with your tongue as hard as you can. After the signal, your result will be displayed on the scoreboard.

But tongue strength is nothing compared to the biggest muscles in your body, like your quads and glutes. Your chewing muscle can also compete for the title of the strongest, if only because it can produce more power with less energy. This is because it is attached to a shorter arm (i.e. your jaw). The bicep, on the other hand, needs to lift your forearm, which is a relatively long lever that requires more energy to move.

Conclusion

So yes, your tongue is made up of eight muscles that have more in common with an octopus tentacle than a trapezius muscle. Perhaps this muscle of the human body is hardly the strongest, but it can take first place in the title of "the strangest muscle in the human body."
