Answer to Problem 1TYR

Correct answer:

Clitoris is an external genital organ in females, which is a similar organ compared to that of the penis in males.

Therefore option (a) is correct.

Explanation of Solution

Justify reasons for the correct statement:

Clitoris is the external genital organ in females. It is similar to the penis in males. Clitoris is derived from the mesonephric duct in the embryo. It is the most sexually sensitive area for inducing orgasm, and it consists of corpus cavernosa connective tissue in the same way similar to the penis. Hence, clitoris is a comparable structure to that of the penis.

Option (a) is given as “Clitoris”

Clitoris is the female genital organ similar to the structure related to penis in males.

Hence, Option (a) is correct.

Justify reasons for the incorrect statements:

Option (b) is given as “Vagina”

Vagina is the tubular structure, which is meant for receiving the penis during intercourse and discharging menstrual fluid. It is entirely different from the male genital organ. Hence, it is wrong answer.

Option (c) is given as “The Vestibular bulbs”

The vestibular bulbs are a pair of subcutaneous erectile tissues. These tissues enclose the vagina and accompany a pair of greater vestibular glands. Both of these structures open into the vestibule, allowing the vulva to stay during intercourse. It is not comparable to that of the male’s penis. Hence, it is a wrong answer.

Option (d) is given as “The labia minora”

Labia minora is derived from the urogenital folds of the embryo. It is meant for sexual stimulation and expansion during child birth. Hence, it is a wrong answer.

Option (e) is given as “The prepuce”

Prepuce is an area at the anterior margin of the vestibule. It is meant for external sexual sensation like that of the foreskin of the penis, but it is not similar to that of the penis.  Hence, it is wrong answer.

Hence, options (b), (c), (d), and (e) are incorrect.

Conclusion

Clitoris is the female genital organ that is similar to that of penis in males.
