mineralocorticoid

Examples of mineralocorticoid in the following topics:

• Other Hormonal Controls for Osmoregulation

  • Angiotensin II raises blood pressure by constricting blood vessels and also triggers the release of the mineralocorticoid aldosterone from the adrenal cortex.
  • Mineralocorticoids are hormones synthesized by the adrenal cortex that affect osmotic balance.
  • One type of mineralocorticoid, known as aldosterone, regulates sodium levels in the blood.

• Congenital Adrenal Hyperplasia

  • Synthesis of cortisol shares steps with synthesis of mineralocorticoids such as aldosterone, androgens such as testosterone, and estrogens such as estradiol.
  • Specific enzyme inefficiencies are associated with characteristic patterns of over- or underproduction of mineralocorticoids or sex steroids.
  • CAH due to deficiencies of enzymes other than 21-hydroxylase present many of the same management challenges as 21-hydroxylase deficiency, but some involve mineralocorticoid excess or sex steroid deficiency.
  • supplying enough glucocorticoid to reduce hyperplasia and overproduction of androgens or mineralocorticoids
  • providing replacement mineralocorticoid and extra salt if the person is deficient

• Adrenal Cortex

  • The outermost layer, the zona glomerulosa is the main site for production of mineralocorticoids, mainly aldosterone, which is largely responsible for the long-term regulation of blood pressure.
  • The primary mineralocorticoid is aldosterone.

• Adrenal Glands

  • These layers form three distinct regions: an outer zona glomerulosa that produces mineralocorticoids; a middle zona fasciculata that produces glucocorticoids; and an inner zona reticularis that produces androgens, which are sex hormones that promote masculinity.
  • The two major hormones produced are the mineralocorticoids and the glucocorticoids.
  • The mineralocorticoids regulate the salt and water balance, leading to the increase of blood volume and blood pressure.
  • The main mineralocorticoid is aldosterone, which regulates the concentration of sodium ions in urine, sweat, pancreas, and saliva.

• Overview of the Adrenal Glands

  • They are chiefly responsible for releasing three classes of hormones mineralocorticoids (aldosterone), glucocorticoids (cortisol), and androgens (DHEA) along with catecholamines (adrenaline), which control a variety of functions including kidney function, metabolism, fight or flight response and sex hormone levels.

• Hormonal Regulation of Stress

  • There are two main corticosteroids: glucocorticoids, such as cortisol, and mineralocorticoids, such as aldosterone.
  • Mineralocorticoids function to regulate ion and water balance of the body.

• The Resistance Reaction

  • In high doses, cortisol begins to act as a mineralocorticoid (aldosteron) and brings the body to a state similar to hyperaldosteronism.

• The Anterior Pituitary

  • The effects of ACTH are upon secretion of glucocorticoid, mineralocorticoids, and sexcorticoids.

• Hormonal Regulation of the Excretory System

  • Because it is produced in the cortex of the adrenal gland and affects the concentrations of minerals Na+ and K+, aldosterone is referred to as a mineralocorticoid, a corticosteroid that affects ion and water balance.

• Extrauterine Effects of Estrogens and Progesterone

  • This combats the blockade of the mineralocorticoid receptor by the previously-elevated level of progesterone.
