Question

Juxtaglomerular apparatus is made of

• A. Juxtaglomerular cell, macula densa and lacis cell
• B. Juxtaglomerular cell, lacis cell and myoepithelial cell
• C. Juxtaglomerular cell, lacis cell and Purkinje cell
• D. Juxtaglomerular cell, macula densa and argentaffin cell

Answer 1

The correct option is A Juxtaglomerular cell, macula densa and lacis cell

Juxtaglomerular apparatus is a part of nephron present beside glomerulus. These are specialized cells where afferent arteriole come in contact with distal convoluted tubule. The Juxtaglomerular apparatus is made up of the Juxtaglomerular cells(specialized smooth muscle cells of the afferent arteriole), macula densa( specialized cells present in the distal convoluted tubule) and lacis cell.

So, the correct answer is 'Juxtaglomerular cell, macula densa and lacis cell'.
