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, groans…and psychiatric overtones.” These structures release a compound that inhibits OPG synthesis, thereby elevating (*) RANKL levels. These structures release 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 stimulates osteoblasts to activate osteoclasts and break down bone. For 10 points, calcitonin is opposed (-5[1])by a calcium-elevating hormone released by what glands (10[1])located adjacent to the thyroid? ■END■
