MORPHOLOGICAL CHARACTERISTICS OF THYMUS GLAND IN YOUNG CHILDREN

Today, one of the most important problems for researchers is the study of the morphology, physiology and pathology of the immune system, which is primarily associated with the demands of clinical medicine, given that new environmental, social and other factors have begun to significantly influence the human body. The thymus gland is the central organ of immunogenesis and the endocrine gland. The structure (macro-microscopic picture) of the thymus was studied on 31 corpses of newborn children. We used anatomical methods (preparation, measurement) and histological methods (histological stain). In the darker, cortical zone, the cells are located very densely, their number is much greater than in the center of the cerebral zone. In the thickness of the medulla, there are single Gassal's bodies, blood capillaries, and lymph gaps. The cortical layer consists of lymphoid elements, very densely located, with mitoses in individual cells. The thymus gland has a delicate thin connective tissue capsule, consisting mainly of elastic fibers, collagen fibers are revealed among the fibers, collagen fibers and interlobular septa are well developed in newborns.
