Symptoms of disease - violation of the locomotor system functions

Locomotive man is also called the locomotor system. It consists of muscular and skeletal systems of the human body, and represents a complex of interconnected bones, muscles, covering the bones and joints, muscles and bones, such as tendons, joints, etc. Number of bones in the human body is a little more than two hundred, muscle same about three times more.

The spine is the Central axis of the body; the main core of the musculoskeletal system; protective «case» to the spinal cord; mobile biomechanical chain, consisting of 33-34 bony vertebrae and 23 of intervertebral discs; polyarticular a coupling with a large number of degrees of freedom, which ensures the maintenance of the vertical position and coordinated movements due to the managed state tendon-muscular apparatus. Cartilaginous part of the spine is: a quarter of the total length of the vertebral column.
Intervertebral disk consists of gelatinous kernel and limiting it annulus fibrosus, and performs three basic functions: connects the vertebral bodies, provides the flexibility of the spine, protects the bells from injury. The resistance of the forces of compression are striking: the height of the normal disk drive with a load of 100 kg decreases by only 1.4 mm, while in the breadth, it increases by only 0.75 mm.

Physiological kyphosis and lordosis and the system of «bell-disk» with the muscle-ligamentous machine, interact, to ensure the implementation of the depreciation of the function.

Line of the center of gravity of the spine passes h/h 1-St neck, body 6 cervical, 9 breastfeeding, 3 lumbar, 3 sacral vertebrae. Finally, all the physiological curves are formed to 18-20 years, keeping the shape of vertebrae, ligamentous machine and the active force of muscles.
Loss of discs dampening properties and protrusion of the fibrous ring leads to the sharp increase in the load on the edge of the vertebrae. In the end this comes their reactive changes.

The main role in the maintenance of the spine in an upright position, the preservation of physiological bends and in the protection of the spine from damage perform: muscular corset and the two most powerful hydrodynamic pillars - the rib cage and abdominal press.

The muscles along with the bones and their compounds are included in the locomotor system, as the active element. In the human body more than 600 of skeletal muscles, the total weight of which is 30-45% of body weight.

Every muscle has a well-developed network of blood vessels. The reduction of muscles promotes more rapid blood flow, i.e., muscle is a kind of a «pump», pumping blood.

In conditions of reduced motor activity (hypokinesia), due to the way of life or a forced bed regime, this function of skeletal muscles is switched off, which slows down the blood flow, leads to stagnation and reduction of the processes of metabolism.

In the conditions of the locomotor activity, on the contrary, there is disclosure of the reserve and the formation of new capillaries, improves the skeletal muscles. Nerve flatware skeletal muscles are presented receptors, perceiving the process of irritation, and effectors», transmitting excitation on the muscle of the Central nervous system.

Number of nerve endings in the muscle depends on the degree of functional activity of muscles. Increase in the number promotes physical load dynamic nature.

Start with the age of involutive changes in skeletal muscle. Violated the ratio of its elements: there is atrophy of the striated muscle tissue, desolated part of the blood vessels, decreasing the number of nerve instruments, at the same time grows fibrous connective and adipose tissue. Systematic physical load hamper development of these changes, and the professional work of the specialists of reversing. The big role in recreational activities plays a desire and a systematic work on a human.

The functions of the musculoskeletal system are to give to the human body a certain form, to protect his internal organs, to provide its support, to allow movement and the adoption of any possible POS.

The functions of the locomotor system
- booster - fixation of the muscles and internal organs;
- protection - protection of vital organs (brain and spinal cord, heart, etc.);
- motor - provision of simple movements, motor action (posture, locomotion and manipulation) and motor activity;
- leaf - mitigation of shocks and vibrations;
- participation in the provision of vital processes, such as mineral metabolism, circulation of the blood, blood-forming and others.

Which diseases there is violation of the locomotor system functions

One of the main causes of diseases of the musculoskeletal system is a lack of motor activity - physical inactivity. It arises in connection with the active replacement of manual labor mechanized, the development of household appliances, vehicles and etc.

Adversely affects the condition of all organs and systems of the body, contributes to the appearance of excess body weight, obesity, atherosclerosis, hypertension, ischemic heart disease.

In elderly people under the influence of the natural age-related changes of nervous structures and the musculoskeletal system are reduced volume and speed of movement, disturbed coordination of complex and delicate movements, weakened muscle tone, there is some constraint. All of this is usually manifested earlier and in a more pronounced form, those who lead a sedentary lifestyle.

The absence of motor activity of the muscles surrounding bone, leads to a disruption of metabolism of the bone tissue and the loss of their strength, hence the poor posture, narrow shoulders, hollow chest and another, what is harmful effect on the health of internal organs.

The lack of sufficient physical activity in a mode of the day leads to a loosening of articular cartilage and modification of surfaces, mating bones, to the appearance of painful sensations are created conditions for the formation in them of inflammatory processes.

Which doctor should I contact if there is a violation of the locomotor system functions

• Neuropathologist
• Traumatologist

Are you experiencing violation of the locomotor system functions? You want to know more detailed information, or you need an inspection? Please sign up on reception to the doctor! Doctors will examine you, examine the external signs and help to determine the disease the symptoms, they will consult you and provide the necessary assistance. You can also call the doctor on the house.

Do you feel disrupted locomotor system functions? You should be very careful approach to your health in general. People pay not enough attention to the symptoms of the disease and don't realize that these diseases can be critically dangerous. There are many diseases that in the beginning didn't manifest in our body, but in the end it turns out, unfortunately, it have already been treated too late. Every disease has its own specific features typical symptoms - called symptoms of the disease. Definition of symptoms is the first step in the diagnosis of diseases in general. You just need a few times a year to be screened by a doctor, not only to prevent a terrible disease, but also to maintain a healthy spirit in a body and the organism in general.
