Detailed explanation-1: -The graafian, or mature, follicle may be up to 2.5 cm in diameter at the time of ovulation, and it protrudes from the surface of the ovary. An outer layer of theca cells and granulosa cells surround a vesicle containing fluid and the oocyte.

Detailed explanation-2: -the Graafian follicle ruptures to release the secondary oocyte, in a process known as ovulation.

Detailed explanation-3: -Rapid secretion of Leutinizing hormone (LH) results in a hormone surge, causing the Graafian follicle to break. This break releases the ovum, resulting in ovulation.

Detailed explanation-4: -Ovulation: The process of an egg being released from the ovary is called ovulation. The egg is released and travels down the fallopian tube, where it remains for 12 to 24 hours before being fertilised. In this process, the Graafian follicle ruptures to release the secondary oocyte (ovum) from the ovary.

Detailed explanation-5: -Ovulation is defined as the process by which a mature ovarian follicle ruptures and releases an ovum (oocyte).
