This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Physiology
Juxtaglomerular apparatus consists of all of the following, EXCEPT: 
Select and explain. 
A. JG cells, B. Macula densa, C. Lacis cells, D. Podocytes
D: Podocytes
Answer: D: Podocytes 
Explanation: The lacis cells, the JG cells, and the macula densa constitute the juxtaglomerular apparatus. Juxtaglomerular cells (JG cells) are epitheloid cells which are located in the media of the afferent aerioles as they enter the glomeruli. Agranular lacis cells are located in the junction between the afferent and efferent aerioles. The macula densa is in close proximity to the JG cells. Ref: (2012). Chapter 38.
