Aldosterone is the main mineralocorticoid steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. [ 4 ] [ 5 ] It is essential for sodium conservation in the kidney, salivary glands, sweat glands, and colon. [ 6 ]
The primary endogenous mineralocorticoid is aldosterone, although a number of other endogenous hormones (including progesterone [1] and deoxycorticosterone) have mineralocorticoid function. Aldosterone acts on the kidneys to provide active reabsorption of sodium and an associated passive reabsorption of water, as well as the active secretion of ...
The following is a list of hormones found in Humans. Spelling is not uniform for many hormones. Spelling is not uniform for many hormones. For example, current North American and international usage uses [ citation needed ] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling ...
Angiotensin II also stimulates the secretion of the hormone aldosterone [6] from the adrenal cortex. Aldosterone causes the renal tubules to increase the reabsorption of sodium which in consequence causes the reabsorption of water into the blood, while at the same time causing the excretion of potassium (to maintain electrolyte balance).
The production of steroid hormones is called steroidogenesis, and involves a number of reactions and processes that take place in cortical cells. [5] The medulla produces the catecholamines, which function to produce a rapid response throughout the body in stress situations. [4] A number of endocrine diseases involve dysfunctions of the adrenal ...
The secretion of aldosterone is also stimulated by adrenocorticotropic hormone (ACTH). [8] The cells of the zona glomerulosa do not express 11β-hydroxylase and 17α-hydroxylase. This is the reason zona glomerulosa cannot synthesize cortisol, corticosterone or sex hormones . [9]
Mineralocorticoid hormones are synthesized in the outermost layer of the adrenal cortex known as the zona glomerulosa. [2] Their function is to regulate the concentration of electrolytes circulating in the blood. [1] For example, aldosterone functions to raise
Steroid hormones help control metabolism, inflammation, immune functions, salt and water balance, development of sexual characteristics, and the ability to withstand injury and illness. The term steroid describes both hormones produced by the body and artificially produced medications that duplicate the action for the naturally occurring steroids.
