Diss In Adrenal Cortex Hormone Secretion

: p Specifications : 2 Pages , 3 Sources , CBE Style: language excogitate the Addison affection , and pheochromocytoma . How it raises in the human dead remainsAddison s disease or ` adrenal gland want is a ascertain in which the adrenal glands do not lay worst sufficient amounts of the ductless gland hydrocortisone (Mayo 2006 . This hormone helps to control the tune pressure cardiovascular action mechanism , tolerant responses , insulin crop , metabolism etc in the body (NIDDK 2004 . In some cases , a hormone that controls the blood pressure and the changeable balance in the body (aldosterone ) is in addition take uped (NIDDK 2004 . The adrenal glands are sacrifice above the kidneys and produce several another(prenominal) hormones required for normal performance of the body (Mayo 2006 . Addison s disease fire occur in both 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 parade in the skull ) control the activeness of the adrenal gland by ensuring proper yield and come forth of the hydrocortisone hormone The hypothalamus produces a hormone CRH (corticotropin-releasing hormone , that stimulates the hypophysis to produce the adrenocorticotrophin hormones that further stimulates the adrenal glands to release cortisol (NIDDK 2004 . Addison s disease whitethorn develop ascribable to deficient issue of cortisol by the adrenal gland ( first-string inadequateness ) or referable to decreased stimulation from the hypophysis gland (secondary lack (NIDDK 2004 . indigenous adrenal insufficiency whitethorn develop payable to an immune dysfunction . Most of the cases of develop due to the body s defending team mechanism attacking the tissues of the adrenal cortex and resu lting in deficient production of the hormone! (NIDDK 2004 . Primary adrenal insufficiency may also develop in association with `Polyendocrine inadequacy Syndrome , in which several hormonal directs are deficient due to a genetic dis (NIDDK 2004 . Several other causes including tuberculosis , infections , phlebotomize , tumors , beam of tumors , surgery , etc , of the adrenal glands could result in primary insufficiency (Mayo 2006 .

Secondary adrenal insufficiency can develop due to reduced production of corticotropin by the pituitary glands or CRH by the hypothalamus (Mayo 2006 . The ACTH production stimulates the adrenal glands to produce cortisol , and the CRH hormone encourages the pituitary to release ACTH (NIDDK 2004 . The level of ACTH is controlled by a negative feedback mechanism . Tumors that affect the pituitary , surgical removal of the gland , radiotherapy to the run and know region , reduced supply 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 especially in seekful conditions such(prenominal) as fright , flight and fight , aflame stress , etc (Mayo 2006 . The tumor develops from the inner portion of the adrenal gland know as `adrenal medulla (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.net
