Abstract:
The aim of this vie is to discuss the general principles of prenatal development of adrenal gland. On the basis of spatial-temporal heterogenity of structural particularites of fetal adrenal cortex, spectrum steroidogenic enzymes and secreting hormones expression in adrenocorticocytes, regulation of proliferation and differentiation processes mechanisms, authors discuss adrenal morphogenesis in three periods of gestation. It was noted the close relationship between placenta development and hypothalamo-pituitary-adrenocortical system formation with specification in each gestation period. Adrenal embryogenesis accompanied by remodeling of structural, functional and biochemical properties of parenchimal-stromal elements of fetal organ. Definitive zonation formation determined by morphogens: ACTH, renal and intraadrenal angiotensin II, estrogens, prostaglandines and other. The action of these factors realization is due to immediately and thought growth factor system (IGF-I, IGF-II, EGF, bFGF), working as paracrine amplificators of morphogenetic signals and activators of transcriptional factors--c-fos and c-jun.

Anatomy of the Adrenal Glands
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
The adrenal gland comprises two distinct regions...
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...
Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
