processes? A glucose stimulated insulin secretion from pancreatic B cells of vasopressin sretion fro the neurohypophysis C.stimulation of thyroxine secretion from thyroid follicular cells D.release of catecholanines from adrenal nedullary cells E.secretion of parathyroid hornone Question #30 If you labeled the pancreas with an antibody to insulin which one of the following you obtain? A staining of the majority of cells in all islets B.staining of only the most peripheral cells in all islets C.staining of some islets but not others D.staining of both islet and acinar cells E no staining because islet cells iediately secrete all the insulin they produce Question 31 In the anterior pituitary.gonadotropes Aare directly contacted by processes of hypothalamic neurons that control their secretion B.are the only cells that derive embryologically from the oral ectoderm C.are distinguished from other pituitary cell types by not using exocytosis for release of hormon D.can produce follicle stimulating hormone (FSH),luteinizing hornone (LH)or both FSH and LH E.are one of the classes of acidophils Which of the following cellular events occur(s)in response to insulin secretion? A.increased degradation of glycogen in hepatocytes B.increased uptake of glucose from the gut lumen by intestinal enterocytes C.increased uptake of glucose by adipocytes and muscle fibers D.increased gluconeogenesis all of the above Question 33 Epinephrine secretion by adrenal medullary cells involves stinulation of A epinephrine synthosis and subsequent diffusion through the plasa mbran caused by corticosterone exocytosis of epinephrine containing granules by acetylcholine D.exocytosis of epinephrine containing granules by adrenocorticotropic hormone (ACTH E none of the above processes? A. glucose stimulated insulin secretion from pancreatic B cells B. stimulation of vasopressin secretion from the neurohypophysis C. stimulation of thyroxine secretion from thyroid follicular cells D. release of catecholamines from adrenal medullary cells E. secretion of parathyroid hormone -------------------------------------------------------------------------------- Question # 30 If you immunolabeled the pancreas with an antibody to insulin, which one of the following results would you obtain? A. staining of the majority of cells in all islets B. staining of only the most peripheral cells in all islets C. staining of some islets but not others D. staining of both islet and acinar cells E. no staining because islet cells immediately secrete all the insulin they produce -------------------------------------------------------------------------------- Question # 31 In the anterior pituitary, gonadotropes A. are directly contacted by processes of hypothalamic neurons that control their secretion B. are the only cells that derive embryologically from the oral ectoderm C. are distinguished from other pituitary cell types by not using exocytosis for release of hormone D. can produce follicle stimulating hormone (FSH), luteinizing hormone (LH) or both FSH and LH E. are one of the classes of acidophils -------------------------------------------------------------------------------- Question # 32 Which of the following cellular events occur(s) in response to insulin secretion? A. increased degradation of glycogen in hepatocytes B. increased uptake of glucose from the gut lumen by intestinal enterocytes C. increased uptake of glucose by adipocytes and muscle fibers D. increased gluconeogenesis E. all of the above -------------------------------------------------------------------------------- Question # 33 Epinephrine secretion by adrenal medullary cells involves stimulation of A. epinephrine synthesis and subsequent diffusion through the plasma membrane caused by corticosterone B. exocytosis of epinephrine containing granules by corticosterone C. exocytosis of epinephrine containing granules by acetylcholine D. exocytosis of epinephrine containing granules by adrenocorticotropic hormone (ACTH) E. none of the above --------------------------------------------------------------------------------
