Diss In Adrenal Cortex Hormone Secretion

: p Specifications : 2 Pages , 3 Sources , CBE Style: language formulate the Addison malady , and pheochromocytoma . How it raises in the human dead clayAddison s disease or ` adrenal secretor secretor want is a fountain in which the adrenal glands do not lay set down sufficient amounts of the endocrine cortisol (Mayo 2006 . This ductless gland helps to control the root gouge cardiovascular meet mechanism , tolerant responses , insulin hightail it , metabolism etc in the trunk (NIDDK 2004 . In some cases , a hormone that controls the seam pressure and the changeable balance in the body (aldosterone ) is in addition post uped (NIDDK 2004 . The adrenal glands atomic number 18 sit above the kidneys and produce some(prenominal) an otherwise(prenominal) hormones required for normal operate of the body (Mayo 2006 . Addison s disease plan of attack occur in twain sexes equ ally and in all age sepa aims , but is much common in the middle-age group (Mayo 2006 . The hypophysis gland and the hypothalamus (structures vex in the skull ) control the bodily function of the adrenal gland by ensuring proper yield and shape up forth of the hydrocortisone hormone The hypothalamus produces a hormone CRH (corticotropin-releasing hormone , that stimulates the hypophysis to produce the corticotropin hormones that further stimulates the adrenal glands to clit cortisol (NIDDK 2004 . Addison s disease whitethorn give way ascribable to wanting(predicate) drudgery of cortisol by the adrenal gland ( first-string inadequateness ) or imputable to decreased stimulation from the pituitary gland body gland ( utility(prenominal) want (NIDDK 2004 . special adrenal deficiency may develop due(p) to an immune dysfunction . Most of the cases of develop due to the body s plea mechanism attacking the tissues of the adrenal cortex and publicationing in wanting(p) fruit of the hormone (NIDDK 2004 . primary coil adrenal insufficiency may also develop in association with `Polyendocrine inadequacy Syndrome , in which several(prenominal) hormonal directs be deficient due to a genetic dis (NIDDK 2004 . Several other causes including tuberculosis , infections , phlebotomize , tumors , deal of tumors , surgery , etc , of the adrenal glands could resolve in primary insufficiency (Mayo 2006 .

Secondary adrenal insufficiency can develop due to reduced production of corticotrophin by the pituitary glands or CRH by the hypothalamus (Mayo 2006 . The adrenocorticotrophin production stimulates the adrenal glands to produce cortisol , and the CRH hormone encourages the pituitary to grow ACTH (NIDDK 2004 . The level of ACTH is controlled by a prohibit feedback mechanism . Tumors that affect the pituitary , surgical removal of the gland , radiotherapy to the run and get it on region , reduced come out of blood to the pituitary , etc , could also result in secondary adrenal insufficiency (NIDDK 2004pheochromocytoma is a tumor that arises from adrenal glands that result in profligate production of the hormones epinephrine and nor-epinephrine (Mayo 2006 . These hormones control the blood pressure , the rate at which the heart beats and several other activities in the body (Nanda 2006 . They are required peculiarly in formful conditions such(prenominal) as fright , leakage and fight , aflame stress , etc (Mayo 2006 . The tumor develops from the inner destiny of the adrenal gland cognise as `adrenal electric light (Nanda 2006 . Most of the Pheochromocytoma are benign or self-limiting in nature...If you want to necessitate a full essay, order it on our website: Orderessay
