Q. No.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. 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 |
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
The signals for parturition originate from:
1. placenta only
2. placenta as well as developed foetus
3. oxytocin released from maternal pituitary
4. fully developed foetus only
