Question

A: Oviducts help in the movement of the oocyte.
R: Mucosal epithelium of the oviduct contains non ciliated cells with microvilli called peg cells.

• A. Both A and R are correct and R is the correct explanation of A.
• B. Both A and R are correct but R is not the correct explanation of A.
• C. A is correct but R is incorrect.
• D. Both A and R are incorrect.

Answer 1

The correct option is B Both A and R are correct but R is not the correct explanation of A.

Oviducts in females serve as the carriers of the oocyte from the site of their origin (ovaries) to the uterus. Oviducts have 3 layers- mucosa, muscularis and serosa. The mucosal layer consists of ciliated simple columnar cells which function as a “ciliary conveyer belt” for the transport of ovum.
It also contains non ciliated cells called peg cells. These cells have microvilli and secrete a nutritive fluid that nourishes the embryo.
