My Notes
What ensures that only one sperm can fertilize the ovum?
1. Corona radiata
2. Ground substance around ovum
3. Zona pellucida
4. Acrosome
Sperm has several components out of which the function of the acrosome is to:
| 1. | Produce base to neutralize the acidic environment of the female reproductive system |
| 2. | Propel the sperm as they swim through the fluid of the female reproductive tract |
| 3. | Release an enzyme that breaks down the membrane of the ovum |
| 4. | Metabolise the sugars provided by the semen for energy |
At what point does the secondary oocyte complete meiosis?
1. when acrosomal enzymes begin to break down the egg's jelly coat
2. when the luteinizing hormone triggers ovulation
3 after it is penetrated by a sperm cell
4. when the secondary oocyte implants in the endometrium of the uterus
Capacitation occurs in
(1) rete testis
(2) epididymis
(3) vas deferens
(4) female reproductive tract
Fertilisation in humans is practically feasible only if
1. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the fallopian tube
2. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the cervix
3. the sperms are transported into cervix within 48 hrs of release of ovum in uterus
4. the sperms are transported into vagina just after the release of ovum in fallopian tube
