Which of the following contains a fluid filled cavity called antrum?
1 Primary spermatocyte.
2 Primary follicle of ovary.
3 Tertiary follicle of ovary.
4 Secondary spermatocyte.
Explanation:
(c) In biology, antrum is a general term for a cavity or chamber, which may have specific meaning in reference to certain organs or sites in the body. Tertiary follicle of ovary contains a fluid filled cavity called antrum and a secondary oocyte ready for ovulation.

Immediately after ovulation, the mammalian egg is covered by a membrane known as
1 chorion
2 zona pellucida
3 corona radiata
4 vitelline membrane
Explanation:
(c) Immediately after ovulation, the layer that forms around the ovum is called corona radiata. It is formed by the granulosa cells of cumulus oophorus. Corona radiata probably increases the likelihood that the ovum will be picked up in the uterine tube.

The figure given below shows the sectional view of ovary. Select the option which gives correct identification of marked structure (A to $D$ ) and its feature.
1 A:Primaryfollicle, it is also called gamete mother cell.
2 B: Corpus luteum, it cannot be formed and added after birth.
3 C: Grafian follicle, mature follicle which ruptures to release secondary oocyte.
4 D: Tertiary follicle, a large number of this follicle degenerates during the phase from birth to puberty.
Explanation:
(c) Oogonia are called as gamete mother cell. Corpus luteum is formed as a temporary endocrine structure after the ovulation. It is involved in the production of relatively high levels of progesterone and moderate levels of estradiol and inhibin A to maintain pregnancy. A large number of primary follicles degenerate during the phase from birth to puberty.
