The macula densa cells are a small subset of approximately 20 cells per nephron at the distal end of henle's loop. They are located near the vascular pole of the glomerulus. 

Cortical nephron refers to nephrons that contain small, short loop of Henle, penetrating only the outer renal medulla. Most nephrons (85% of the total nephron) in the human kidney are cortical nephrons.

We can say it but its not mentioned clearly that cortical nephrons have Macula dense cells.
