KROK 1 2016 – Question 3 · KROK (Medicine) · Histology, Cytology, and Embryology
Histologic specimen of a kidney demonstrates cells closely adjoined to the renal corpuscle in the distal convoluted tubule. Their basement membrane is extremely thin and has no folds. These cells sense the changes in sodium content of urine and influence renin secretion occurring in juxtaglomerular cells. Name these cells:
- A. Podocytes
- B. Glomerular capillary endothelial cells
- C. Juxtaglomerular cells
- D. Macula densa cells
- E. Mesangial cells
Hint
Consider the cells of the juxtaglomerular apparatus and ask which of them belong to the tubule rather than to the vessels or the glomerulus.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
