The other solid arrows either indicate a secretion from an organ (blue, with a starting spot) or a reaction (black). These 2 processes can be stimulated or inhibited by other factors. This work is based on File:Renin-angiotensin-aldosterone system.png , which was created by User:A._Rad~commonswiki
The pituitary gland (or hypophysis) is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity (sella turcica) covered by a dural fold (diaphragma sellae).
Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. [citation needed] Deoxycorticosterone is another important member of this class. Aldosterone tends to promote Na + and water retention, and lower plasma K + concentration by the following mechanisms:
The following is a list of hormones found in Homo sapiens.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 gonadotrophin.
The outermost layer, the zona glomerulosa is the main site for the production of aldosterone, a mineralocorticoid. The synthesis and secretion of aldosterone are mainly regulated by the renin–angiotensin–aldosterone system. The zona glomerulosa cells express a specific enzyme aldosterone synthase (also known as CYP11B2).
The glucocorticoid receptor.. The corticosteroid receptors are receptors for corticosteroids. [1] Corticosteroid receptors mediate the target organ response to the major products of the adrenal cortex, glucocorticoids (principally cortisol in man), and mineralocorticoids (principally aldosterone).
The innermost layer of the cortex, the zona reticularis, produces androgens that are converted to fully functional sex hormones in the gonads and other target organs. [4] The production of steroid hormones is called steroidogenesis, and involves a number of reactions and processes that take place in cortical cells. [5]
By this method, body diagrams can be derived by pasting organs into one of the "plain" body images shown below. This method requires a graphics editor that can handle transparent images, in order to avoid white squares around the organs when pasting onto the body image. Pictures of organs are found on the project's main page. These were ...
