Muscles - what is it? The importance of muscles in the human body

Every element of the human body performs a certain function. All of them are extraordinarily important. An important role in the body and its normal functioning is played by muscles. What it is, you can find out from our article. Muscles are the organs of the body, which consist of muscle tissue. They contract under the influence of nerve impulses.

Functions of muscles and their structure

Muscles - an active element of the musculoskeletal system. They provide a variety of movements. The importance of muscles in the human body is invaluable. Thanks to them, the balance is maintained, the walls of internal organs are reduced, and voice formation takes place.

Because of the connection with the skeleton, the muscles are often called skeletal muscle. In the human body, there are more than 500. They occupy 30% of the body weight.

Any muscle consists of bundles of muscle fibers. They are connected due to loose connective tissue. The functional value of the muscles is large enough. It depends on them how strong and enduring this or that person.

The connective layer, which is located between the muscle beams, passes into the tendon part of the musculature and is attached to the bone. The movement takes place due to the contraction under the influence of nerve impulses.

Surprisingly, each of the muscles is a separately formed organ. They have a certain form, structure and function. The musculature is provided with blood vessels and nerve fibers. For each movement, several muscles respond at once. During any action, shortening of the muscular abdomen occurs. Due to this, the tendons pull the bone behind them. So this or that movement is made.

By the nature of the performance of certain movements, the following types of muscles are distinguished:

• Flexion and extensor;
• Leading and withdrawing;
• Rotating;
• Lifting and lowering;
• Mimic;
• Chewing;
• Respiratory.

Types of muscles, their structure and meaning are known to every athlete. Strong muscles are a guarantee of good health. In the human body there are three main types of muscles:

• Skeletal;
• Smooth;
• Heart.

It is known that men have about 10% more musculature in the body than women.

Experienced athletes recommend newcomers to learn all the information about muscles in advance. Thanks to this, you can better understand the structure of the body and increase the effectiveness of training.

Smooth muscles participate in the formation of the walls of internal organs and vessels. They continue to work independently of the human consciousness. This process can not be stopped. They work continuously throughout the life of a person.

There are also skeletal muscles. What is it is known to all doctors. This muscle group is responsible for maintaining balance. It is thanks to skeletal musculature that a person can accurately and smoothly perform various movements. It's amazing, but while people just sit still, dozens of various muscles work in the body. Skeletal musculature can be controlled. Intensive activity leads to fatigue.

Cardiac muscles simultaneously combine some functions of skeletal and smooth muscles. They are able to work intensively and shrink. Heart muscles do not feel tired and work throughout their life.

Meaning of the word

Everyone knows the word "muscle". Obsolete importance of muscles is not familiar to everyone. Earlier in the Slavic languages, this word pointed to the hand, and not to the organs that are present throughout the body. Philologists often notice the connection between the words "muscle" and "mouse." This is evidenced by the various languages of the Indo-European group. According to research, in the ancient Greek language the word "mouse" was used in the meaning "musculature".

In Old Icelandic, one of the words also had several meanings - "mouse" and "muscle." Their relationship is obvious to any specialist.

Little is known also that in ancient times the word "mouse" indicated the muscle under the shoulder bend. However, in part it is present in the old sense and in the modern world. Today everyone knows what an armpit is. This word comes from the ancient name of the muscle under the shoulder joint.

Everyone knows what a muscle is. The meaning of the word, according to the explanatory dictionary Ushakov, may have several variations. In the first case, it is the organ of movement in a person or animal, in the second hand. The latter option is marked as obsolete and bookish.

Muscles of the face

Mimic muscles are muscles that are located on the face. They are unusual, because one part is attached to the bone, and the other - to the skin. Each such muscle is in the connective shell. From the point of view of anatomy, facial muscles do not have fascia.

What is the use of mimic muscles and what does it matter? The facial muscles allow the person to demonstrate their emotions. This or that facial expression is formed in connection with the contraction of facial muscles.

Mimic muscles - thin and small bundles. They are located near the natural openings, namely around the mouth, nose, eyes and ears. Mimic muscles indicate a different kind of human experience.

Crick. Symptoms and treatment

Strong muscles are the result of many years of training. Many athletes perform a set of special exercises every day. Frequent workouts can lead to stretching. It is important to carefully monitor your condition during classes.

Stretching of the muscle is a traumatic injury to the muscles or connective tissue. It can occur with excessive strain on the body. Stretching of the muscle can occur in the home. In this case, the trauma is associated with hard physical work or in an uncomfortable position.

It is known that the most frequent stretching of muscles is associated with sports. In this case, excessive muscle tension can lead to serious health problems. Such an injury can be obtained after a strong muscular contraction. Stretching often occurs after doing stretching exercises. Experienced athletes do not recommend making sudden movements when practicing sports - it is traumatic.

When the muscles are stretched, the patient experiences pain and swelling in the area of the injury. In some cases, hematoma may form. The nature of the pain can be different. When stretched, it can be either weak or sharp. There may also be small scars.

Treatment of stretching can take several days, and a couple of months. At the reception the specialist will determine which muscles have been damaged and will prescribe the appropriate therapy. Most often, such a trauma is accompanied by sprain. In this case, the rehabilitation period will take a long period of time.

When stretching the muscles, first of all, the patient is put ice into the area of the resulting injury. This process should not be less than 20 minutes. After 48 hours, after the injury was received, experts recommend that the affected area be provided with heat.

Muscle cramp

Muscle cramps are characterized by sudden or involuntary painful contractions of the musculature or part of it. This disorder usually occurs in people who have had a spinal cord injury.

Which muscles are most prone to cramps? Most often, spasms are troubling in the foot or calf muscles. Seizures also often occur in the quadriceps muscle.

Muscle spasms can occur for many reasons. Their overstrain is one of the main. Often, convulsions are associated with dehydration of the muscles. The lack of potassium, calcium and magnesium in the daily diet contributes to the development of spasms in the musculature.

It is important to know how to prevent muscle cramps and treat them. Prevention is the best way to avoid this problem. The key factor to prevent spasm is diet and moderate muscle tension. A balanced diet, which includes all the necessary vitamins and minerals, should become part of the habitual way of life. Replenish the lack of potassium, calcium or magnesium can be with the help of special vitamins.

People who are actively engaged in sports, it is necessary to perform a warm-up before training. If you feel a spasm, you need to stretch the problem area as soon as possible. This will normalize the process of muscle contraction. Specialists also recommend that you visit the massage room as often as possible to prevent seizures.

With muscle cramps, one or more muscles can contract. In some cases, they can cause severe pain. Muscle cramps can occur with prolonged exercise or heavy physical labor during the heat wave. Sometimes muscular spasms appear after the taking of certain medications.

Symptoms of muscle cramps include: the unexpected occurrence of pain, most often in the lower limbs; Formation of hard tissue sites.

Muscular spasms are rarely a sign of any serious problem. Most often they pass without outside interference. However, the doctor will have to turn if the spasms are systematic, bring discomfort and are not associated with any obvious reasons. Moderate training improves blood circulation, thereby reducing the risk of seizures.

What importance do the muscles of a person know, not by hearsay athletes. They regularly attend training sessions in order to make them stronger and more enduring. Muscles play an important role in the health of a person.

How to turn fat mass into muscles?

In order to quickly and effectively get rid of excess weight, you must give preference to regular training and proper nutrition. Due to this, the fat mass is gradually replaced by muscle mass.

In people who begin the process of weight loss, fat deposits act as energy for the formation of muscle mass. Carbohydrates are energy material. People who want to get rid of excess weight, it is recommended to reduce the amount of consumption of carbohydrate products. In this case, the amount of energy supplied is reduced. The body uses existing fat deposits. Thanks to the received energy, he forms muscles. This process is most noticeable at the initial stage. It is because of the formation of muscle mass, at first the weight of the person who wants to lose weight remains in place, and the volumes go away. The muscles of the body gradually become stronger and more enduring. Improves the general condition of the body and well-being. When replacing fat deposits with muscle mass, it is necessary to attend training routinely. Otherwise, it will not be possible to achieve a good result.

Strong and hardy muscles at home: myth or reality?

Many argue that it is impossible to pump muscle at home. Is it so?

Quite often, people with excess weight and weak muscles can not get rid of these problems, because they do not have the opportunity to visit the gym. They believe that exercises performed at home are ineffective. However, any doctor or sportsman can say with confidence that such an opinion is erroneous. Any systematic physical activity is the way to a healthy and fit body, as well as strong muscles. Undoubtedly, classes with special equipment in the gym is more efficient and comfortable. However, you can achieve great results without leaving home.

Strengthening of the muscles will occur gradually. The main thing is regular training and balanced nutrition. To strengthen the muscles, you need to squat, press, pull, and do the exercises that form the ideal press. You can also use improvised tools. Thanks to their extra weight, it will be possible to achieve the desired results in the shortest possible time.

As an additional weight, you can use anything you like. These can be bottles of water or sand, as well as weights. Experts recommend starting training without improvised means to reduce the risk of muscle strain. Over time, you can use additional weight.

Strengthening the muscles in the home has a lot of positive qualities. There is no need to adjust to a specific time. You can strengthen the muscles when it is most convenient. At home there is no large crowd of strangers. It's no secret that quite often people with a weak muscle mass and excess weight are embarrassed to attend gyms.

Rigidity of muscles: symptomatology, treatment, causes

Often there is rigidity of the muscle. What it is, you can find out in our article.

Rigidity of the musculature is a painful condition characterized by their increased tone and resistance when trying to make a passive movement. Having such a problem, it is impossible to completely relax the muscles. Rigidity arises from a disturbance in the work of the nervous system. It is not a separate disease. Stiffness is just a symptom that can arise on the basis of other disorders.

Sometimes stiffness arises from monotonous work, which takes place in the same pose. It often occurs in drivers and system administrators. Such work leads to the appearance of spasms and painful sensations. In order to get rid of the rigidity of the muscles, you just need to start exercising. However, if it is caused by a more serious illness, sports will not help.

Muscle stiffness can also be observed in newborns. Such a violation occurs in them without any interference. However, you need to see a doctor if the symptoms persist for a long period of time. With rigidity in children, there is constant tension and violation of reflexes. About pathology can also symbolize that the newborn early began to hold his head. Normally this occurs no earlier than 6-8 weeks after birth.

As we said earlier, the rigidity of the muscles is not an independent disease, therefore it is necessary to treat not the symptom, but the cause of its occurrence. It is from her that the chosen therapy will depend.

To improve the general condition, it is recommended to reduce the load on the affected area. It is also important to visit the massage room regularly. In the presence of severe pain, it is recommended to use painkillers. Folk remedies can only be used after consultation with a specialist. The doctor can prescribe a course of vitamin therapy in case of rigidity of muscles. It is also necessary to use special orthopedic devices. They will allow to provide the affected area of muscle tissue with complete rest.

Hyperplasia and hypertrophy

Among athletes there are such concepts as hyperplasia and muscle hypertrophy. That this is not known to everyone. Hyperplasia of the muscles is characterized not by a qualitative improvement in the musculature, but in an increase in their number.

As a rule, when a person regularly performs physical exercises, he increases the number of myofibrils in muscles. Volumes become more due to thickening of muscle tissue. This process is called hypertrophy.

Athletes tend to achieve hyperplasia (an increase in the number of cells). However, it is difficult to do this. Before you start to increase the number of muscle cells, you need to pay attention to what is already available. It is worth noting that the process of hyperplasia requires a large amount of energy. To stimulate it, it will be necessary to create accelerated protein synthesis. It will be necessary to eat foods that contain amino acids. Some athletes also recommend using anabolic hormones. However, in some cases, they can be dangerous and harmful to the body.

Summing up

Muscles - one of the active elements of the musculoskeletal system. It is thanks to them that a person can make certain movements. Many underestimate their role. It is known that often because of weak muscles there are headaches, discomfort in the back and heaviness when walking. For the prevention of a variety of diseases it is important to regularly perform physical exercises. Thanks to them, the muscles become strong and enduring. A person with such a musculature is full of energy. He rarely experiences headaches and malaise.
