  • Question 5

    Perineum is the area in the female reproductive system that lies.
    Solution
    In the female reproductive system, the perineum is the area that lies between the vaginal opening and the anus. It represents the most inferior part of the pelvic outlet. Thus it lies above the external genitalia.

  • Question 6
    1 / -0
    What is height and weight of twelve week old human embryo?
    Solution
    During the gestational period of around 9 months, the human fetus undergoes gradual weight and height gain. The average height and weight of a healthy human embryo at 12 weeks of age are around 6 cm and 14 g, respectively.
    Out of the given options, 7.5 cm and 14 gm are the figures nearest to the right answer.
    So, the correct answer is '7.5 cm, 14 gm'.

    Solution
    Permanent surgical method for birth control in male human beings is vasectomy. During the procedure, male vas deferens are severed and then tied or sealed in a manner so as to prevent sperms from entering the urethra and thereby prevent fertilization.
    Hysterectomy is the removal of the uterus, which is a female reproductive organ. 
    Dialysis is done to purify blood in case of kidney failure.
    Tubectomy is a permanent surgical method for birth control in female human beings. During the procedure, fallopian tubes are cut and then tied to prevent passage of eggs to the uterus for implantation.

  • Question 9
    1 / -0
    What is the height and weight of twelve weeks old human embryo?
    Solution
    • During the embryonic period, organs and tissues are differentiated. This period is about the growth of an embryo both in size and weight. 
    • At 12 weeks, the size of the embryo is as big as fig. 
    • The height of a human embryo is about 7.5 cm in length and its weight is 14 grams. 
    • At this stage, the fetal heartbeat is audible by Doppler ultrasound. The sex can be determined at this stage by ultrasound techniques. 

    Thus, the correct answer is option B.
  • Question 10
    1 / -0
    During the menstrual phase, uterine endometrium, epithelial glands, and connective tissues are broken. This is due to
    Solution
    Menstruation or the menstrual phase involves the shedding off of the uterine endometrium, epithelial glands, and connective tissues via the vaginal canal. On events that fertilization of the ovum released by the ovaries does not take place, the progesterone levels dip down and this results in the shedding of the extra, surrounding tissues of the uterus along with the unfertilized and degenerating ovum.
    So, the correct answer is 'Lack of progesterone'.
