Question
Juxtaglomerular apparatus is made up of
juxtaglomerular cell, macula densa and lacis cell
juxtaglomerular cell, Purkinje cell and chied cell
juxtaglomerular cell, lads cell and myoepithelial cell
juxtaglomerular cell, macula densa and Argentaffin cell
Solution
A.
juxtaglomerular cell, macula densa and lacis cell
In juxta medullary nephrons, only the initial portion of distal tubule forms a complex with the afferent arteriole's wall. This complex is called juxtaglomerular complex or juxtaglomerular apparatus. It includes:
(a) granular juxtaglomerular cells in the afferent arteriole.
(b) macula densa cells of Distal Convoluted Tubule (DCT).
(c) agranular polkissen or lacis cells situated in between the above two.
