Q. No.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
The first movements of the foetus and the appearance of hair on its head are usually observed during which month of pregnancy?
1. Fourth month
2. Fifth month
3. Sixth month
4. Third month
The second maturation division of the mammalian ovum occurs:
| 1. | Shortly after ovulation before the ovum makes entry into the Fallopian tube |
| 2. | until after the ovum has been penetrated by a sperm |
| 3. | until the nucleus of the sperm has fused with that of the ovum |
| 4. | in the Graafian follicle following the first maturation division |
