The study of the individual spatial topography and the morphological structure of the human diaphragm was performed according to the data of a multi-sectional spiral computed tomography. In total - 85 studies of people of both sexes. Men - 70 and women - 15. In most studies, the mesomorphic structure of the body prevailed (56%), the proportion of brachi- and dolichomorphs accounted for 32% and 12%, respectively. Men in the first and second mature ages were more than women - 65% and 35% respectively, and in older adults, women predominated - 72%, compared with 28% of men. The following indicators were studied: the height of the dome walls of the diaphragm, corresponding to the conditional lines in the frontal plane; the angles of joining the diaphragm to the chest wall along the same lines and planes. During the study of the tendon center of the diaphragm, the diameters of the holes (aortic, esophageal and hollow veins), distances between them, angular relationships, and their location relative to the middle line were studied. Particular attention was paid to the pericardial site. Studied its transverse and longitudinal dimensions, location relative to the central line (the angle of the location). In order to detect the morphological features of the diaphragm, sectional material was used in this study. As a sectional material, the diaphragm of men and women (n = 7) aged 25 to 45 years is studied. For the study of the morphological features of the diaphragm, the following methods of coloration such as hematoxylin and eosin, picrofuxin by Van Giezon. Processing, studying and virtual aperture modeling was carried out at the Hewlett-Packard 8020 workstation with the use of the specialized program "Vitrea 2". All received digital data were subjected to statistical processing - correlation analysis to determine the possible dependence of these indicators on gender, age and body type. It was established that the type of structure of the body has a weak correlation with the diameter of the aortic aperture - r=0.45, the distance between the aortic orifice and the inferior vena cava - r=0.39, the length and width of the aorta - r=0.25 and 0.35 respectively, the height of standing right dome. The posterior axillary line is 0.31, the height of attachment of the right dome in the middle axillary line is 0.23, and the height of the right dome along the anterior axillary line is 0.31. Other indicators were not related to the age of the person. The age was related to the diameter of the esophagus (hiatus diameter) - r=0.29, the distance between the aortic orifice and the inferior vena cava - r=0.22, the distance between the opening of the nerve and the esophagus - r=0.32, as well as the height of the dome along the posterior axillary line to the right and the height of the dome along the anterior axillary line to the right - r=0.27 and 0.22, respectively, with a weak correlation relationship. Instead, a strong correlation between the aortic apertures is 0.75. Other indicators were not related to the age of the person. The person's gender was associated with a weak correlation with the diameter of the aortic aperture - r=0.46, the diameter of the esophagus - r=0.31, the distance between the aortic orifice and the inferior vena cava - r=0.46, the distance between the opening of the inferior vena cava and the esophagus - r=0.42, the width of the pericardial site - r=0.3 and the height of the dome along the middle axillary line to the right - r=0.28. Other indicators were not related to the human article. In general, we can conclude that the spatial topography of the diaphragm directly depends on the location of the upper body organs of the abdominal cavity.
