Neurohumoral regulation of muscle activity. The influence of hormones on muscle
The concept of functional systems was mainly based on the study of motor behavior reactions. According to P. K. Anokhin, starting stimulus activity of an organism is the physical factor, which acts on the background of the situational afferentation during the synthesis process in the higher parts of the brain interfaced with congenital and acquired experience (memory) and the dominant motivation. On this basis there is a choice of one or more directed paths functioning of the body, called the decision an
adaptive character.
The adopted program with the target unit (the acceptor of result of action) via efferent pathways delivers the Executive signal which actuates the working devices: occur muscle contraction,secretion of glands, etc. and Then from the relevant receptors in the acceptor of the action comes reverse afferentation message about the result of the act. If the latter does not reach the target fixture installation, then the reaction is repeated or adaptation is another way. Continue reading
The influence of exercise on the body and strengthening health
It is known that regular physical activity and sports practice many organs and systems of the human body, which, of course, improves health and improves health.
The movement is a very important component of health. It stimulates many processes in the body. Child couldn’t grow into a full adult human if he did not commit such a huge amount of different movements.
In our body contains about 65% of liters of liquid, and it must be continuously circulated, so that the cells received all necessary materials, and waste is removed. The liver, kidneys, lungs, skin and intestines must be healthy and clean in time to eliminate the toxins.
The multiple increase circulation of fluids in the bodycontributes to the movement: running, walking, exercise. When we move, our muscles contract, the liquid is extruded into the blood stream, and venous blood moves to the heart.
Thanks to increased blood circulation and respiration, are emitted from the body the toxins of fatigue, resulting in the impact on human performance. Continue reading
