Abstract
The scientific literature rarely contains data on the number, density, location of the small glands of the vestibule and their morphogenesis. The aim of the study was to obtain complex quantitative macro-microscopic data on small glands of the vestibule in the postnatal ontogenesis. The material of the study was 299 total histological preparations of the glands of the vestibule of vagine walls obtained at autopsy, beginning from the period of the newborn to the period of longevity inclusive. Fixed preparations were placed in a 0.5% acetic acid solution with 0,05% methylene blue solution. At the level of the middle third of the vestibule, transverse sections were performed with further staining with hematoxylin-eosin, picro-fuxin according to Van Gison, according to Weigert, according to Craigberg, and Grimelius silvering reaction. The analysis showed that throughout the entire postnatal ontogenesis glands of the vestibule with one initial section predominate. The glands of the vestibule are fully formed by the time the baby is born. Beginning with the period of the newborn and up to the period of the first adult age, the glandular apparatus of the vestibular vestibule develops actively. Beginning with the second period of adulthood and until the senile age, inclusive changes occur in the small glands of the vestibule. In the old age, the shape of the glands becomes much simpler and their number decreases with three, four or more initial sections, the gland content grows with one initial department.
