    We used ultrastructural morphometry to examine submicroscopical organization of spatial contacts between the C-cells and perifollicular hemocapillaries in the thyroid gland of 2-, 4-, 12-, 26-, and 52-week-old rats desympathized with guanetidine. We found that desympathization does not affect typology of ultrastructural elements of the hemato-C-cellular complex, and predominant coupling of the vascular pole of the C-cell with peripheral zone of endotheliocyte highly effective in terms of transport. Postnatal changes of certain parameters of the hemato-C-cellular system, however, undergo some statistically significant changes. Under experimental conditions, we observed the formation of hemato-C-cellular contacts simultaneously involving two C-cells.

    Synthesis and Regulation of Thyroid Hormones

    Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
    Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

    Functions of Thyroid Hormones

    The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
    TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

    Graves Disease II: Pathophysiology

    Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
