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 if estrogen and progesterone |
4. | High level of hCG stimulates the thickening of the endometrium. |
Which one of the following is not the function of placenta?
1. | Secretes estrogen |
2. | Facilitates removal of carbon dioxide and waste material from embryo |
3. | Secretes oxytocin during parturition |
4. | Facilitates supply of oxygen and nutrients to embryo |
Which one of the following statements is false in respect of viability of mammalian sperm?
1. | Sperm is viable for only up to 24 hours |
2. | Survival of sperm depends on the pH of the medium and is more active in alkaline medium |
3. | Viability of sperm is determined by its motility |
4. | Sperms must be concentrated in a thick suspension |
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, the amount of total gonadotropin activity was assessed. The result expected 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 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. Glocagon
4. Androgens
Sertoli cells are found in:
1. | ovaries and secrete progesterone |
2. | adrenal cortex and secrete adrenaline |
3. | seminiferous tubules and provide nutrition to germ cells |
4. | pancreas and secrete cholecystokinin |
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. testis to epididymis
1. C-Infundibulum, D-Fimbriae, E-Cervix
2. D-Oviducal funnel, E-Uterus, F-Cervix
3. A-perimetrium, B-Myometrium, C-Fallopian tube
4. B-Endometrium, C-Infundibulum, D-Fimbriae
1. | escaping any possible compression by the visceral organs |
2. | providing more space for a large epididymis |
3. | providing a secondary sexual feature for exhibiting the male sex |
4. | maintaining the scrotal temperature lower than the internal body temperature |
