THE STRUCTURE PECULIARITIES OF THE GLANDS IN THE URINARY BLADDER WALLS

Abstract

The article presents the results of a research conducted to study the morphological peculiarities (age, individual and regional characteristics) of the glands of urinary bladder in the different age stages of the postnatal ontogenesis in the norm. The glands by macro-microscopy method investigated on preparations of a wall of the urinary bladder in quantity 73, received from corpses. Victims from the casual reasons at the age from the period newborn to senile age and we investigated variants of the form of a bladder glands, feature of its change in different sites of a wall of organ (proximal, middle, distal thirds), taking into account age. Glands have preliminary been painted 0.05% by a solution methylene dark blue with Sinelnicov’s method. The glands in the walls of the human urinary bladder in postnatal ontogenesis are characterized with the age peculiarities. As, in the 1st mature period the total quantity of the urinary bladder glands, their alveoli departments and the quantity of complex glands increase and reaches maximum ontogenetic value. After 1st mature age periods at elderly and senile ages, an involution of glands is noted. The glands of the human urinary bladder are characterized with the individual features. The individual minimum and maximum percentages of glands in the urinary bladder gradually increase from the newborn period to senile age. The glands of the human urinary bladder in postnatal ontogenesis are characterized with the regional features. The quantity, density of glands, the quantity of complex glands are less in the proximal part of the urinary bladder wall than in the middle and distal parts of all age groups. This concerns the location sphincters in the lower third-distal part of the urinary bladder.
