PMDC Verified Question 55 of 99
Nephrons whose renal corpuscles lie adjacent to the corticomedullary junction and possess long loops of Henle extending deep into the inner medulla are called:
A
Cortical nephrons
B
Juxtamedullary nephrons
C
Outer cortical nephrons
D
Subcapsular nephrons

Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Juxtamedullary nephrons
Concept: Structural types of nephrons.

Solution: Juxtamedullary nephrons make up ~15% of human nephrons. Their corpuscles lie near the medulla, and their long loops of Henle extend deep into the renal pyramids to establish the hyperosmotic medullary gradient.

Why other options are incorrect:
  • Option A, Option C & Option D: Cortical/subcapsular nephrons make up ~85% of nephrons; their corpuscles lie in the outer cortex and their short loops of Henle barely penetrate the outer medulla.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
