KROK 1 2015 – Question 2 · 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. Mesangial cells
- C. Macula densa cells
- D. Juxtaglomerular cells
- E. Glomerular capillary endothelial cells
Hint
Think about the parts of the juxtaglomerular apparatus and which one monitors the composition of the tubular fluid rather than filtering, supporting or secreting.
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.
