The basis for determining the lifetime of the embryos

Despite the fact that, in a sense, pre-embryo is formed in the gametes from which it was formed, how it running again appeared individual born after conception. The time span of existence after insemination embryo homo sapiens, has got into the laboratory for study, almost never known, except for the most serious data. Even when the fetus has a particularly full of doctors' testimony, notices as usual based only on the patient's attempts to recall the circumstances of their sex lives. Assuming that the information on the previous menstrual marked in the diary, yet remains unknown to the time of the sexual cycle, when the patient had a specific place to be ovulating. If the integrity of the study, we assume that the time release of an egg from the ovary and possibly sexual union, which became prosperous, defined, and in this case we are able to find the period of colonization with certainty from half a day to a day. If the fetus with an extremely detailed description obtained by spontaneous miscarriage, still unclear when he died. We will not have to conclude that, for how much before the birth of its formation and snapped destruction began. According to the stage of absorption of the body of the embryo, which at times can be seen in the chorionic vesicles thrown out, it is clear that the interval between the death of the fetus and abortions can be substantial. These intervals are too varied, in order to be able to do as much as possible the exact opinion on their duration in each particular use case. In the best condition of the fetus extracted in medical operations. When properly sprawling embryo separated during the operation, we have the knowledge to within at least the time of its destruction.

All of the above emphasizes the significance of the increased collection as possible particularly accurate description of each use case, where it was necessary to interrupt the pregnancy surgery, and explains the principles of collecting this information about the development of the embryo, coupled with carefully left nucleus for the survey medlaboratorii where the fruit will be measured, followed investigated by other methods that are needed to establish the stage of maturation. Only the analysis of all the data can be identified to increase the reliability of our data on the phenomena that take place during the ongoing life of the unborn.

All this is further simplified by using the name freaks PAGUS suffix (Greek - connect), attached to the anatomical appellation of fusion, for example: kraniopagus - connection of the head with the head; torakopagus - connection of the chest pigopagus - joining the pelvic area, and so on (Fig. 118).

Lateral accretion, apparently, begins either in the head or in the breech end and never occurs at the level of the chest. Often, however, the lateral accretion is more extensive, and the chest is the second time it involved
