The follicle that ruptures and releases the ovum during the ovulatory phase is known as a Graafian follicle since it is completely developed.
The corpus luteum, which secretes progesterone and is necessary for maintaining pregnancy, develops from the Graafian follicle after ovulation.
The granulosa cells and oocytes are situated in the follicular fluid, which is also the medium via which regulatory chemicals should travel to and from this milieu.
