KROK 1 2011 – Question 41 · KROK (Medicine) · Histology, Cytology, and Embryology
A histological specimen of a kidney shows a part of the distal tubule going between the afferent and efferent arteriole. The cells building the tubule wall have dense nuclei; basal membrane is absent. Such structural formation is called:
- A. Macula densa
- B. Juxtavascular cells
- C. Juxtaglomerular cells
- D. Mesangial cells
- E. -
Hint
Decide which component of the juxtaglomerular apparatus is formed by the wall of the tubule itself, as opposed to the wall of a vessel or the cells inside 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.
