Question 1 - Single Best Answer
Identify the structure at the tip of the arrow:
E) distal straight tubule
Sorry...
Since distal straight tubules are located in the medullary rays, most of the tubules present should be oriented parallel to each other without turns or bends evident in the section. Distal straight tubules typically have a smaller outside diameter, a more rounded lumen, and a sharper luminal surface. In addition, they do not have a brush border.
