A protrusion within the Graafian follicle containing the oocyte is known as what?

Explanation:
The oocyte is surrounded by a cluster of granulosa cells that forms a projection into the follicular fluid, known as the cumulus oophorus. This structure contains and supports the oocyte within the Graafian follicle and remains attached to the follicle wall as the follicle matures. The zona pellucida is the protective coat surrounding the oocyte itself, not a protrusion. The theca externa is the outer fibrous layer of the follicle, and the antrum is the fluid-filled cavity inside the follicle.
