Under certain conditions of life on earth it was possible the development of some representatives of ancient apes otherwise than in other animals, direction. Qualitative feature of these beings manifested in the ability to produce artificial tools. At first, very primitive and crude, they became an important addition to the organs of the body, its natural guns. They were further technical equipment of man, which made it possible to produce a purposeful, conscious change of nature, adapting it to their needs. The ability to create synthetic instruments, the capacity for creative work gradually Read more [...]

Second, in contrast to the unconditioned (innate) reflexes are impermanent. If you developed a reflex saliva born not support food (ie, not given food after a light signal), the amount of saliva gradually separated at ignition light will decrease, and then completely stopped. Conditioned reflex extinguished. However, the extinction of conditioned reflexes persist well-trodden path, the extinction of a conditioned reflex - this is just off, or, as they say, its inhibition. This phenomenon is also an active process. Termination of a batch of the unconditioned stimulus, supporting formed a conditioned Read more [...]

Once upon a time it is known that allocation Saliva is not only a result of chemical receptors in the oral mucosa. Side properties of food - the sight and smell it and even just thinking about food - cause salivation to food. The nature of this everyday phenomenon has long been unclear. Therefore, in the era of dopavlovskuyu scientists distinguish physiological salivation, on the one hand, and mental saliva - on the other. It was clear that the "physiological" saliva is the type of unconditioned reflex, which is caused by chemicals of food (Fig. 52, 53), a phenomenon described by Read more [...]

Central nervous system, that is, the part of the nervous system, which is concentrated centrally manage all functions of the body, is found only in vertebrates. According to modern concepts, the nervous system Vertebrate evolution goes through three stages of development. At the lowest members of this class * it is presented in the form of the neural tube, which extends along the body and the spinal cord is quite similar to the more highly developed animals. The formation of the nervous system of this type in the development process was driven by the need to concentrate all the control centers Read more [...]

But it would be wrong to think of the nervous system as a kind of congestion reflex arcs. In fact, due to the huge number of intermediate neurons virtually all nerve cells are connected by direct or roundabout ties. So. during stimulation of a single receptor can get a lot of reflex responses. For example, the stimulation of the receptors of the mouth causes a reflex secretion of saliva, but it does not stop there: both stand pancreatic juice and the gastric glands, the nature of circulation of these bodies, some changes in the heart, respiratory system, etc. But all reflex acts are coordinated Read more [...]

The development of such a new form of the nervous system, characteristic of the earth to man, has led to a completely new principle of adaptation to life. All living things adapt to natural conditions. Man, however, thanks to the work and mind transforms nature, adapting it to their needs. "Natural selection does not apply to the person, as it adapts to the nature does not change the physical type, and the development of a variety of natural conditions of their labor." * In the central nervous system focused not only control the movement and behavior of the device, it also carries Read more [...]

There are other examples. So, if you change the amount of sugar in the blood of the nervous system connects the corresponding endocrine glands, the selection of doses of hormones that control metabolism. For example, an excess of sugar in sweet food after taking the pancreas secretes more insulin, and excess sugar under the action of insulin stored in the liver and muscles as glycogen, and when under heavy muscular work, when there are increased consumption of sugar included adrenal glands, and hormone adrenaline mobilizes glycogen in transition sugar of blood.

Major role in the regulation of body functions and ensuring its integrity belongs to the central nervous system and the higher parts - the cerebral cortex. Structure nervous system extremely difficult, and many aspects of its activities remain a mystery. But modern science is on the approaches to the knowledge of the most intimate secrets of this amazing and probably the only one in the universe mechanism. Now science has knowledge of the basic laws of nervous activity, which were discovered the work of many brilliant researchers and especially the genius of Russian scientists XIX-XX centuries.

Others serve only to connect the different parts of the brain and spinal cord and can only be called intercalary, or connection, the neurons. The third group of nerve cell signals are transmitted from the brain and spinal cord to the muscles or glands are called motor. All information of the central nervous system at the expense of the analyzers, the study of which has been created by Pavlov. Analyzer is a three-term system, consisting of the sensory organs (receptors), a sensory nerve and nerve cells in the cerebral cortex (the central link of the analyzer).

Missed miscarriage is a condition in which the fertilized egg perishes even in relatively early stages of pregnancy, but the expulsion of his still does not, despite the bleeding, indicating the beginning of a miscarriage.

Bowel obstruction and pregnancy

Under normal conditions of compression intestine during pregnancy does not occur, despite the increase in the volume of the uterus and displacement of internal organs. Intestinal motility and the possibility of significant changes gut lumen can adapt to the new conditions arising during pregnancy. Therefore, cases of intestinal obstruction during pregnancy is rare. The incidence rate of ileus - 1 in 50,000 births. In Russian literature, the first case described by IM Tarnowski in 1877 and AP Joffe (clinical professor. Mandelstam AE) in 1933 collected 214 cases.
