The General idea of the motive activity of people

Motor activity of the people depends on many factors: hereditary and acquired qualities and professional activity of a person, his fitness and endurance, character course of various diseases, including the musculoskeletal system.
It is well known that persons engaged in physical labor, moving quickly and easily. This is because in the course of performing this type of work requires dexterity, endurance, speed and harmonious movements, especially if the work is connected with the mechanization and automation of production. With the weakening of one of these parts can be an emergency, to disrupt the production process with all the consequences. On the contrary, a person with mental labour, leading a sedentary lifestyle, mainly develops hypokinesia - reducing motor activity of all organs and systems. This is because during mental work actively involved cortical areas of the big hemispheres of the brain, which are the mental functions, and included little or almost do not participate motor cells crust that part of the brain that control motor activity of the person.
The process of movement is extremely complex. The mechanism of its implementation is extremely diverse, and involves tens of millions of nerve cells and fibers, hundreds of thousands muscle and bone structures, tens of tendons and cartilage formation, hundreds of ligaments and fibrous capsules - they all take part in the creation of complex design of the locomotor organs.
Of great importance in improving motor action have systematic training. Who does not know how difficult everyday work of the ballerina and as graceful in her movements. With neuromuscular and osteoarticular systems it under the influence of emotions reveals the deep meaning of the ballet of the plot. Who has not seen the athlete with his massive muscle layers outlined biceps, with huge deltoid, breast, fine teeth, and the intercostal muscles. SARS such athlete is based on synchronous developed powerful muscles of the pelvis, hips and legs. Naturally, with such a developed nervous-muscular and bone, joint, cardiovascular and respiratory systems it is capable under the influence of psychoemotional stress to do what never can perform ordinary untrained people.
On the athlete, as in any other specialist, you can demonstrate a close relationship between form and function of organs and systems, between their anatomy and physiology. The more expressed in skeletal muscle a person has, the more intense their functional ability than trenirovka its functional activity, the more powerful becomes the muscle of education.
These external relationships are formed in humans in the development of deep and complex metabolic processes in each muscle and bone cell, each of connective tissue and cartilage formation. To ensure such intense metabolic processes under the influence of functional load increases the transport of energy and plastic materials, hormones and biologically active substances, and also accelerates the evacuation of metabolites to the excretory organs - lungs, kidneys, skin, and intestines.
Like no other functional system, musculoskeletal system is closely linked to other organs and body systems. This is due primarily to the fact that the function of any segment of this apparatus is carried out using various delicate and intricate arrangements involving primarily the nervous and vascular elements. At the heart of their actions are reflex and neurohumoral components that have developed in the process of evolutionary development of man. Therefore, if you have even the slightest defect in the amount of some particle micron) in the structure of this device during power reflex motor chain (in nerve and muscle cells and their appendixes, including synaptic entities) may occur locally acute and even reflected pain, leading to spasm prekapilliarnae and capillary regional systems. Such fleeting processes can cause a reduction in transport-evacuation functions, the development of tissue hypoxia and lead to degeneration into defective cells, especially in the synovial membrane, vascular network, ligaments, etc. But these local changes are not so strong that it has developed a pathological process, rather, they begin to dominate the processes of destruction over the creation.
Doctors know very well that the aggravation of discogenic chest pain can increase the pain in the heart area, especially in patients with chronic coronary heart disease, or cause unpleasant sensations in the stomach or biliary system, if these persons are hidden flowing stomach ulcer or duodenal ulcer, cholecystitis or spastic colitis. On the contrary, when the ulcers often exacerbated pain in the area of the nerve roots level VIII-IX of the thoracic vertebrae. This unfortunate turn or excessive bending of the body can cause sharp pain in face-sacral or intervertebral joints of the spine, especially when beginning to form Bechterew's disease. No less painful surrounds the pain in the chest that appear in cases when the disease captures verhnebakansky or nizhnegorodski spine. These processes are interdependent and show how locomotor apparatus with his nerves, joints, and fibers, arterial, venous and lymphatic vessels, ligaments and skeletal muscles is connected with the most important organs and systems management and maintenance of such a complex biological giant, which is the human body.
