Document Summary

Which of the following hormones enters its target cells before exerting its biological effect? (a) adrenocorticotropic hormone (acth) (b) catecholamines (c) dehydroepiandrosterone (dhea) Dhea is a steroid hormone, steroid hormones act on receptors located in the cytoplasm and the nucleus, therefor the hormone must enter the target cell upon exerting its biological effects. Other steroid hormones include aldosterone and cortisol (d) prolactin. A person with an under-functioning pituitary gland will experience functional decline of many systems. All of the following are likely to occur except: (a) dwarfism if it occurs in childhood. Possible cause of gh deficiency directly related to pituitary function (b) impaired testosterone secretion in a male. Possible cause of lh deficiency directly related to pituitary function (c) deficiency of aldosterone. Aldosterone is produced through the raas pathway, angiotensinogen is constantly produced, and converted to ang i by renin and ang ii by ace, ang ii acts on the adrenal cortex stimulating the secretion of aldosterone.
