About the morphological peculiarities of the glands and lymphoid structures of the urinary bladder in the postnatal ontogenesis

Abstract

In a postnatal ontogenesis of glands and lymphoid structures of a urinary bladder are characterized with the regionar localization, age, specific and genital features. At all stages of a postnatal ontogenesis the quantity and density of glands and lymphoid structures in the lover part of a urinary bladder are more, than in upper and the middle parts. The quantity and morphometric indexes of glands and lymphoid structures in a sphincter more those near a sphincter. In a postnatal ontogenesis the genital peculiarities of glands and lymphoid structures of an organ discovered at teenage, youthful and I mature ages. To these structures is characteristic also the age features. At the earliest stage of a postnatal ontogenesis, i.e. at the newborn the glands of a urinary bladder have well formalizated. The greatest development it is noted in I mature age. After those periods – at elderly and senile ages ares noted an involution of glands. Lymphoid structures as much as possible develop at early childs age. After this age there is a morphological regress of a lymphoid tissue. Glands and lymphoid structures of a urinary bladder of the man are characterized by individualy features. Their broad individual variability at mature, elderly and senile ages is established.
