Identify the cell that can be seen in primordial, primary, secondary and tertiary follicle :
1. | oogonium | 2. | primary oocyte |
3. | secondary oocyte | 4. | ovum |
The number of mature ova produced by a young, healthy, nonpregnant adult woman each year would be:
1. | 0 | 2. | 6 |
3. | 12 | 4. | 24 |
The correct chronology in the ovarian cycle in a non-pregnant woman would be:
1. | corpus luteum > ovulation > primary & secondary follicles > vesicular follicle |
2. | primary & secondary follicles > vesicular follicle > ovulation > corpus luteum |
3. | ovulation > primary follicles > corpus luteum > secondary & vesicular follicles |
4. | ovulation > primary & secondary follicles > corpus luteum > vesicular follicle |
If pregnancy is established, the corpus luteum:
I: | is no longer needed because of hormones produced by the pre-embryo |
II: | typically continues to secrete progesterone through the third month of pregnancy |
III: | transforms into a corpus albicans soon after the placenta is fully functional |
1. | I and II are correct | 2. | I and III are correct |
3. | I and II are incorrect | 4. | II and III are correct |
Identify the correct statement:
1. | GnRH stimulates the production of estrogen [in females] or testosterone [in males] directly |
2. | LH stimulates ovulation (female) or spermatogenesis (male) |
3. | FSH initiates and maintains the development of accessory sex organs (both sexes) |
4. | estrogen stimulates oogenesis (female only) |
Identify the cells that are haploid: (1) spermatogonia (2) primary spermatocytes (3) secondary spermatocytes (4) spermatids (5) spermatozoa
1. | 1, 2, and 3 | 2. | 2, 3, 4, and 5 |
2. | 3, 4, and 5 | 4. | 4 and 5 only |
After leaving the testes, spermatozoa pass sequentially through the :
1. | seminiferous tubule, rete testis, efferent ductule, and epididymis |
2. | epididymis, ductus deferens, seminal vesicle, and ejaculatory duct |
3. | membranous urethra, prostatic urethra, and spongy urethra |
4. | epididymis, ductus deferens, ejaculatory duct, and urethra |
The onset of puberty in males and females is due to the release of:
1. | LH |
2. | FSH |
3. | GnRH |
4. | hCG |
In the ovaries of a girl child, what is basically happening?
1. atresia of primordial follicles
2. completion of meiosis I by primary oocytes
3. formation of antral follicles
4. completion of metaphase II by some oocytes
The most common site of fertilization is:
1. infundibulum
2. ampulla
3. isthmus
4. fimbriae
