Question

Proximal convoluted tubule differs from distal convoluted tubule being lined by ______ 

Options

• Squamous cells with few microvilli

• Cuboidal cells with few microvilli

• Cuboidal cells with many microvilli

• Squamous cells with many microvilli

Answer 1

Proximal convoluted tubule differs from distal convoluted tubule being lined by Cuboidal cells with many microvilli.

Explanation:

PCT is lined by brush border cuboidal cells lined by microvilli as maximum reabsorption occurs in this region whereas DCT is mainly concerned with secretion process and absorption is very little so brush border is absent.
