GH B. TSH C. somatostatin D. prolactin E. ACTH (Question 4) Elevated ACTH can cause skin darkening, due to its ability to: A. bind to the MC1R B. stimulate cortisol production C. bind to the CRH receptor D. stimulate adrenal androgen production E. stimulate -MSH production (Question 5) A 50-year-old woman complains that in the past few months she has had little energy, has frequently felt chilled, and has noticed excessive hair loss when she washes her hair.

The glycoprotein hormones from the pituitary include: A. thyroid-stimulating hormone, growth hormone, luteinizing hormone B. human chorionic gonadotropin, thyroid-stimulating hormone, follicle-stimulating hormone C. prolactin, growth hormone, adrenocorticotropic hormone D. follicle-stimulating hormone, luteinizing hormone, thyroid-stimulating hormone E. follicle-stimulating hormone, luteinizing hormone, prolactin (Question 9) Hypothalamic releasing hormones are secreted from neuroendocrine neurons at the: A. median eminence B. pars distalis C. paraventricular nucleus D. pars nervosa E. infundibular stalk (Question 10) A drop in blood Ca++ will indirectly increase renal 1 hydroxylase activity. This occurs in response to: A. elevated 25-hydroxyvitamin D B. elevated PTH C. elevated Pi D. elevated calcitonin E. elevated 24-hydroxylase activity Title: An example of a short loop feedback is: Post by: Gizzy10 on Feb 22, 2018 - - - - - - - - - - - - - - - - - - - - - - - - - - - Title: An example of a short loop feedback is: Post by: albulena on Feb 22, 2018 Thank you very much!!!
