Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
As the follicle prodded by FSH grows larger, it accumulate fluid in the central chamber called the antrum, and the primary oocyte it contains replicates its chomosomes and continues meiosis producing a secondary oocyte.
A
Follicular Phase
B
Ovulation Phase
C
Luteal Phase
D
None of the above
Explanation: 

Detailed explanation-1: -A follicle with more than one layer of granulosa cells is called a secondary follicle (sometimes referred to as preantral). Eventually, fluid-filled vesicles appear in the granulosa cell layer, forming early antral follicles. The vesicles coalesce to a single fluid-filled antrum.

Detailed explanation-2: -Antral follicles are characterized by the formation of a fluid-filled cavity called the antrum. During this stage, the GCs that originally enclose the oocyte differentiate to two distinct cell subtypes, cumulus cells (CCs) and mural GCs.

Detailed explanation-3: -Oocytes in preovulatory follicles are suspended in follicular fluid by a stalk of granulosa cells, the cumulus oophorus.

Detailed explanation-4: -Tertiary follicle of ovary contains a fluid filled cavity called antrum and a secondary oocyte ready for ovulation.
