Which of the following cells during gametogenesis is normally diploid?
1. | Primary polar body |
2. | Spermatid |
3. | Spermatogonia |
4. | Secondary polar body |
The shared terminal duct of the reproductive and urinary system in the human male is:
1. | Urethra | 2. | Ureter |
3. | Vas deferens | 4. | Vasa efferentia |
The main function of mammalian corpus luteum is to produce
1. estrogen only
2. progesterone
3. human chorionic gonadotropin
4. relaxin only
Select the correct option describing gonadotropin activity in a normal pregnant female
1. High level of FSH and LH stimulates the thickening of endometrium
2. High level of FSH and LH facilitate implantation of the embryo
3. High level of HCG stimulates the synthesis of estrogen and progesterone
4. High level of HCG stimulates the thickening of endometrium
Menstrual flow occurs due to lack of
1. progesterone
2. FSH
3. oxytocin
4. vasopressin
Which one of the following is not the function of the placenta?
1. | It facilitates the supply of oxygen and nutrients to the embryo |
2. | It secretes oestrogen |
3. | It facilitates the removal of carbon dioxide and waste material from the embryo |
4. | It secretes oxytocin during parturition |
Signals for parturition originate from
1. both placenta as well as fully developed foetus
2. oxytocin released from maternal pituitary
3. placenta only
4. fully developed foetus only
In a normal pregnant woman, total gonadotropin activity was assessed. The expected result was :
1. | High level of circulating FSH and LH in the uterus to stimulate implantation of the embryo |
2. | High level of circulating HCG to stimulate endometrial thickening |
3. | High levels of FSH and LH in the uterus to stimulate endometrial thickening |
4. | High level of circulating HCG to stimulate oestrogen and progesterone synthesis |
The Leydig cells as found in the human body are the secretory source of:
1. | progesterone | 2. | intestinal mucus |
3. | glucagon | 4. | androgens |
If for some reason, the vasa efferentia in the human reproductive system get blocked, the gametes will not be transported from:
1. epididymis to vas deferens
2. ovary to uterus
3. vagina to uterus
4. testes to epididymis
