mellékvesekéregben
Mellékvesekéregben refers to the adrenal cortex, the outer layer of the adrenal gland. This endocrine tissue is crucial for producing a variety of steroid hormones essential for life. It is divided into three distinct zones, each with its own characteristic cell types and synthetic capabilities. The outermost zone, the zona glomerulosa, is responsible for the production of mineralocorticoids, primarily aldosterone. Aldosterone plays a vital role in regulating electrolyte balance, particularly sodium and potassium levels, and consequently influences blood pressure and fluid volume.
Moving inward, the zona fasciculata is the thickest layer of the adrenal cortex and synthesizes glucocorticoids,
The innermost layer of the adrenal cortex is the zona reticularis. This zone produces androgens, which are
