Question

They’re not kidneys, but these structures are systematically associated with a sclero·choroidal condition that presents with multiple, ill-defined yellow placoid lesions. Adenomas in these structures can be detected by a sestamibi scan, which localizes Tc99 to their oxy·phil cells. These structures are the most likely cause of a condition whose symptoms are described as “stones, bones, (-5[1])groans…and (-5[1])psychiatric overtones.” These structures release a compound that inhibits OPG synthesis, thereby elevating (*) RANKL levels. These structures release (-5[1])a compound that upregulates alpha-1-hydroxylase, which promotes phosphate reabsorption by catalyzing the activation of Vitamin D. It’s not the stomach, but chief cells in these glands release a compound that counterintuitively (10[1])stimulates osteoblasts to activate osteoclasts and break down bone. For 10 points, calcitonin is opposed by a calcium-elevating hormone released by what glands located adjacent to the thyroid? (0[1]) (0[3])■END■

ANSWER: parathyroid glands [accept parathyroid hormone; prompt on PTH; reject “thyroid”] (The first line refers to sclerochoroidal calcification. The second line refers to hypercalcemia.)
