Question

Cuboidal epithelium with brush border of microvilli is found in?

• A. proximal convoluted tubule of nephron
• B. eustachian tube
• C. lining of intestine
• D. ducts of salivary glands

Answer 1

The correct option is A

proximal convoluted tubule of nephron

The correct option is A.

Explanation of Correct option:

1. Cuboidal epithelium is made up of cube-like cells with a large central nucleus.
2. A brush border epithelium is characterised by the presence of microvilli over its surface.
3. These microvilli greatly increase the surface area of the epithelium enhancing absorption and secretion of products.
4. The proximal convoluted tubule of the nephron is lined by cuboidal epithelium with a brush border of microvilli.

Explanation of Incorrect option:

Option B:

Eustachian tube lining is made up of ciliated columnar epithelium.

Option C:

The intestinal lining is made up of columnar epithelium,

Option D:

Ducts of salivary glands are lined by cuboidal epithelium.

Final answer:

Cuboidal epithelium with brush border of microvilli is found in the proximal convoluted tubule of the nephron.
