A specimen presents an endocrine system organ covered with capsule made of connective tissue. Septa branch off from the capsule inwards and divide the organ into lobules. Each lobule consists of two cell types: neurosecretory pinealocytes (polygonal cells with processes) located in the center and gliacytes (astrocytes) located at the periphery. What organ is represented in this specimen? O Adrenal medulla Epiphysis Thyroid gland Pituitary gland O Hypothalamus

Hi, can you please help me with the following multiple choice question - Thanks!! Correct cause-and-effect relationships following insulin withdrawal in a person with diabetes mellitus include: the ratio of K+ concentration inside the cell to K+ concentration outside the cell decreases in untreated diabetes for multiple reasons, including intracellular H+ buffering, which results in a shift of K+ to the extracellular compartment. ketonemia does not increase urine flow because it is entirely reabsorbed in the renal tubule urinary phosphate decreases because renal excretion of H+ results in increased phosphate reabsorption. serum sodium rises because of fluid shift from the extracellular compartment to intracellular compartment. glomerular filtration rate increases as a result of increased serum glucose concentration. The most effective direct stimulus for the release of glucagon is: an increase in serum glucose an decrease in serum glucose somatostatin insulin (direct action on the…
