Answer 1

QUESTION 1

Which of the following statements regarding uterine function is not correct?

Answer - a. The cervical region of the uterus is the most likely site of successful implantation.

The most likely site of successful implantation is the posterior and superior part of uterine cavity. All other statements are correct.

QUESTION 2

Cryptorchidism, or failure of testis to descend out of the abdomen decreases male fertility & is a major risk factor for testicular cancer.

Answer- True

A lower body temperature is required for the testis to act in a proper manner.That is, it should be below the body temperature that is why it is placed in the scrotal sac.When it is placed in the abdomen the testis has to face the body temperature and this will destruct the seminiferous tubules ,which helps in production of sperm.In people with Cryptorchidism the risk of testicular cancer is high compared to normal people.

QUESTION 3

Which structure of the male reproductive system is responsible for the production of majority of volume in semen /seminal fluid?

Answer - a. The prostate

It produces about 20 % semen. The main content of semen produced from prostate is proteolytic enzyme and acid phosphatase.

QUESTION 4

In humans, separation of the cells at the post fertilization stem only state, before differentiation of cells / tissues may lead to the production of what?

Answer - a. Identical twins.

Identical twins arises due to cleavage of zygote immediately after fertilization. Normally fraternal or dizygotic twins develop due to two different sperm fuses with two ovum.

QUESTION 5

The hormone progesterone is responsible for which of the following changes in reproductive anatomy or physiology?

Answer - b. Myometrium growth

Progesterone is known as pregnancy hormone. It helps to maintain pregnancy.It helps in growth of myometrium. Healthy myometrium is essential for maintainance of pregnancy.

QUESTION 6

Which of the following statements concerning the mammary glands is correct?

Answer - d. Mammary glands are highly modified type of sweat gland.

Both male and female can have breast cancer but female sex are more prone to breast cancer. The cancer lump will be mostly immobile. The area more prone for breast cancer is upper and outer quadrant of breast. It is more closer to armpit.
