Question

In human, oviduct is formed by
A. Wolffian duct
B. Bidders canal
C. Metanephric duct
D. Mullerian duct

Answer 1

Hint: Oviduct is the passageway that originates from the ovaries to the outside of the body. It is also called uterine tube or fallopian tube.

Complete answer:
Oviduct is the tube through which the eggs travel. These eggs are either fertilized when they combine with the sperm to form the zygote and if they are not fertilized they are degenerate in the body. Let us analyze the options to find out the correct option.

Option A: Wolffian duct which is also called mesonephric duct is a paired embryogenic tubules that drain the primitive kidney to the cloaca. It serves as the anlage for male reproductive organs.Therefore, this is the incorrect option.

Option B: Bidders canal is present inside the kidneys of the frog and it receives sperms from testes from a number of vasa efferentia.Therefore, this is the incorrect option.

Option C: Metanephric duct is a duct or a tubular portion that forms the epithelial lining of the ureter.Therefore, this is the incorrect option.

Option D: Mullerian ducts are also called paramesonephric ducts. These are the paid ducts of the embryo that runs down the urogenital ridge and ends at sinus tubercle. They are found in both males and females. However, in females they develop into reproductive organs of the female reproductive system while in males they get degenerated.Therefore, this is the correct option.

Hence, the correct answer is option (D)

Note: In females, the mullerian duct differentiate to form the fallopian tubes, uterus, the uterine cervix, and the superior aspect of the vagina.
