Q. No.The main function of mammalian corpus luteum is to produce:
1. Oestrogen only
2. progesterone
3. human chorionic gonadotropin
4. relaxin only
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
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 |
Vasa efferentia are the ductules leading from:
1. Testicular lobules to rete testis
2. Rete testis to vas deferens
3. Vas deferens to epididymis
4. Epididymis to urethra
