Morphologıcal characterıstıcsof glands with s-shaped curvature ın general excretory duct on the walls of the human urınary bladder


Huseynova Gulgiz Agahasan

The wall elements of the tubular organs were investigated by different scientific works. However, the general excretory duct apparatus of the small glands in the walls of urinary bladder has not been examined for its age, individual or genital characteristics.The aim of the research is to investigate the general excretory duct of the glands in the urinary bladder wall, its direction, morphological changes (width, diverticulum, S-shaped curvature, and ect.) and frequency, age, individual and regional characteristics in postnatal ontogenesis.The investigation was carried out on 34 cadavers using macro-microscopic and histological methods. According to the results of the investigation, in the 1st mature period of postnatal ontogenesis, the quantity and density of all glands of the urinary bladder and the area and the quantity of excretion cells of ​​the alveoli increase, also the proximal portions of the ductal apparatus of the glands expand. These signs are closely related to the "morphological equivalent of function". The general excretory duct of the glands on the urinary bladder wall has a straight direction or a curvature arc. Some glands also form an S-shaped curvature in old age. In contrast, the distal part of the general ductus dilates in the elderly and is expanding near the duct foramen. The quantityof the glands with S-shaped curvature on the urinary bladder, compared with newborns, increases in the 1st period of adulthood by 8.3 times (p <0.05), in older people by 9.6 times (p <0.05), in senile age 12.5 times (p <0.05). The individual minimum and maximum percentages of glands with an S-shaped curvature of the general excretory duct in the urinary bladder gradually increase from the neonatal period to senile age.The exclusion of the minimum and maximum values ​​of the glands that make the general duct S-shaped curvature in the urinary bladder wall also increases in maturity and old ages. The diapers on the wall of human urinary bladder glands having a general excretory duct with S-shaped curvature or bulb-shaped widths are also characterized by regionality. Our studies have shown that the quantity of these glands is less in the upper third of the bladder wall than in the middle and lower third of all age groups in postnatal ontogenesis. In this aspect, like the sphincters of the tubular and cavitated organs, the sphincters of the urinary bladder are correct in a similar structure plan (triple muscle and compressed nerves, veins) direction the urine and prevent urinary reflux - urine escaping back to the ureters and kidneys. This is related to the location and functional-morphological proximity of the urethral sphincters and internal urethral sphincter in the lower third of the urinary bladder.
