D.binds to a carrier protein in the blood plasma E.stimulates steroid secretion by target cells Question#39 When cells of the adrenal zona glomerulosa are exposed to angiotensin II,the major secretory product they release A stimulates ACTH secretion from the anterior pituitary B.stimulates glycogen breakdown in hepatocytes stimlates sodiu recovery by distal tubules of renal nephrons D.inhibits water recovery by collecting tubules of renal nephrons E accelerates spermatogenesis Question #40 lodinated thyroglobulin leves in the are nearly thyroglobulin is efficiently filtered by the kidneys and excreted in urine B.is rapidly phagocytosed by macrophages C.undergoes efficient transcytosis in the liver and is excreted in bile D.never leaves the lumen of the thyroid follicle E is mostly degraded in lysosomes of follicular cells Question #41 Which of the following is released from the axon terminals in the pars nervosa [posterior pituitary]? A Vasopressin B Corticotronin C.Growth hormon releasing factor D.Thyroxine [T4] E.Estrogen Question 42 Releases glucagon in response to hypoglycemia ticA [alpha]cells B.Pars distalis [anterior pituitary] C.Adrenal medulla D.Adrenal cortex E.Pancreatic B [beta]cells Question#43 In the islets of Langerhans A.the alpha cells out-number the peripheral beta cells B.the delta cells produce glucagon D. binds to a carrier protein in the blood plasma E. stimulates steroid secretion by target cells -------------------------------------------------------------------------------- Question # 39 When cells of the adrenal zona glomerulosa are exposed to angiotensin II, the major secretory product they release A. stimulates ACTH secretion from the anterior pituitary B. stimulates glycogen breakdown in hepatocytes C. stimulates sodium recovery by distal tubules of renal nephrons D. inhibits water recovery by collecting tubules of renal nephrons E. accelerates spermatogenesis -------------------------------------------------------------------------------- Question # 40 Iodinated thyroglobulin levels in the circulation are nearly always negligible because thyroglobulin A. is efficiently filtered by the kidneys and excreted in urine B. is rapidly phagocytosed by macrophages C. undergoes efficient transcytosis in the liver and is excreted in bile D. never leaves the lumen of the thyroid follicle E. is mostly degraded in lysosomes of follicular cells -------------------------------------------------------------------------------- Question # 41 Which of the following is released from the axon terminals in the pars nervosa [posterior pituitary]? A. Vasopressin B. Corticotropin C. Growth hormone releasing factor D. Thyroxine [T4] E. Estrogen -------------------------------------------------------------------------------- Question # 42 Releases glucagon in response to hypoglycemia A. Pancreatic A [alpha] cells B. Pars distalis [anterior pituitary] C. Adrenal medulla D. Adrenal cortex E. Pancreatic B [beta] cells -------------------------------------------------------------------------------- Question # 43 In the islets of Langerhans A. the alpha cells out-number the peripheral beta cells B. the delta cells produce glucagon
