Inside the kidney the cortical region extends in between the medullary pyramids as renal pelvis.
Glomerulus alongwith Bowman’s capsule is called the renal corpuscle.
Renal corpuscle, proximal convoluted tabule (PCT) and distal convoluted tubule (DCT) of the nephron are situated in the cortical region of kidney.
