Which of the following describes the unique histological feature of glomerular endothelial cells?
Show answer and explanation
Correct answer: They possess large fenestrae lacking diaphragms
Glomerular endothelial cells are highly attenuated and perforated by thousands of fenestrae (70–90 nm in diameter). Unlike most other fenestrated capillaries, these openings generally lack a diaphragm, facilitating high-volume filtration.
