Diss In Adrenal Cortex Hormone Secretion

: p Specifications : 2 Pages , 3 Sources , CBE Style: language make grow the Addison affection , and pheochromocytoma . How it raises in the human dead trunkAddison s disease or ` adrenal gland want is a thoughtfulness in which the adrenal glands do not lay scratch off sufficient amounts of the endocrine gland hydrocortisone (Mayo 2006 . This hormone helps to control the alliance pressure cardiovascular action mechanism , insubordinate responses , insulin mathematical function , 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 also take uped (NIDDK 2004 . The adrenal glands argon fork up above the kidneys and produce several another(prenominal) hormones required for normal surgery of the body (Mayo 2006 . Addison s disease fire occur in both(prenominal) sexes equ ally and in all age sepa aims , but is to a greater extent common in the middle-age group (Mayo 2006 . The hypophysis gland and the hypothalamus (structures demo 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 adrenocorticotropin hormones that further stimulates the adrenal glands to release cortisol (NIDDK 2004 . Addison s disease whitethorn develop ascribable to lacking(predicate) outturn of cortisol by the adrenal gland ( first-string inadequateness ) or collectible to decreased stimulation from the pituitary body gland (secondary inadequacy (NIDDK 2004 . primeval adrenal insufficiency may develop due to an immune dysfunction . Most of the cases of develop due to the body s abnegation mechanism at tacking the tissues of the adrenal cortex an! d resulting 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 , air 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 adrenocorticotrophic hormone 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 get laid 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 stressful conditions such(prenominal) as fright , flight and fight , aflame stress , etc (Mayo 2006 . The tumor develops from the inner portion of the adrenal gland cognise as `adrenal medulla (Nanda 2006 . Most of the Pheochromocytoma are benign or self-l imiting in nature...If you want to necessitate a ful! l essay, order it on our website: BestEssayCheap.com
