Juxtaglomerular apparatus consists of all of the following, EXCEPT:
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.
