Question

Cuboidal epithelium with brush border of microvilli
is found in :
(1) ducts of salivary glands
proximal convoluted tubule of nephron
(3)
eustachian tube
lining of intestine​

Answer 1

Answer:

proximal convoluted tubule of nephron (PCT)

Answer 2

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

Answer:

Option 2 is right

Explanation:

EPITHELIAL TISSUE:

• These tissues form the outer covering of organ and forms the lining of cavities.

• Epithelial tissues are mainly involved in the functions like secretion, absorbtion, filtration, gaseous exchange, etc.

• They play limited role in protection.

• Different types of epithelial tissues include squamous epithelium, cuboidal epithelium, columnar epithelium, etc.

• Epithelial tissues may be simple or compound depending upon the number of layers arranged.

CUBOIDAL EPITHELIUM:

• The cells of this tissues are cuboidal in shape.

• Their main function is secretion and absorption.

• When the cuboidal cells bear cilia on their surface , they are called ciliated cuboidal epithelium.

• When microvilli is associated with cuboidal cells, they are brush bordered cuboidal epithelium.

• This type of brush bordered cuboidal epithelium is found in proximal convoluted tubule PCT of nephron.

• Since it has microvilli, rate of absorption is maximum in this area.

OTHER OPTIONS:

• Ducts of salivary glands are lined by compound cuboidal epithelium, having many layers of cuboidal cells.

• Eustachian tube is lined by ciliated columnar cells.

• Intestine is lined by brush bordered columnar cells bearing micro villi.
