Which one of the following is not the function of placenta?

1. facilitates supply of oxygen and nutrients to embryo

2. secretes oestrogen

3. facilitates removal of carbon dioxide and waste material from embryo

4. secretes oxytocin during parturition

Which one of the following statements is false in respect of viability of mammalian

sperm?

1. Sperm is viable for only up to 24 h

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

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. 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

The figure given below depicts a diagrammatic sectional view of the female

reproductive system of humans. Which one set of three parts out of A-F have been

correctly identified?

2. D-Oviducal funnel, E-Uterus, F-Cervix

3. A-Perimetrium, B-Myometxium, C-Fallopian tube

4. B-Endometrium, C-Infundibulum, D-Fimbriae

The testes in humans are situated outside the abdominal cavity inside a pouch called scrotum. The purpose served is for

Sertoli cells are found in

1. ovaries and secrete progesterone

2. adrenal cortex and secrete adrenalin

3. seminiferous tubules and provide nutrition to germ cells

4. pancreas and secrete cholecystokinin

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 second maturation division of the mammalian ovum occurs

1. shortly after ovulation before the ovum makes entry imto the Fallopian rube

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
