One difference between an MA and MS degree that some students donât think of is whether the degree is a terminal one. A terminal degree is the highest type of degree that an individual can receive in his or her field. An MA is usually a terminal degree, while an MS degree prepares students for working on their doctoral degrees later.
Aldosterone secretion is controlled by the RAA system and by concentrations of K+ in the circulation, which if increased evokes secretion of aldosterone.
*Adrenocorticotropic Hormone (ACTH) -Minor role in aldosterone release-Secreted by anterior pituitary *Renin causes aldosterone to be produced *Renin released in response to: -Low blood sodium (hyponatremia) -High blood potassium (hyperkalemia) -Decreased blood volume/blood pressure-Sympathetic stimulation.Primary aldosteronism-Conn's syndrome-Characterized by high aldosterone and low renin-Renin levels are low due to negative feedback-Caused by adrenal cortex tumor *Secondary aldosteronism-Characterized by high aldosterone and high renin-Caused by high renin production in the kidney.
