Notes
During follicle maturation, the granulosa cells proliferate to form many layers around the oocyte. A boundary layer, the zona pellucida, appears between the oocyte and the granulosa cells. After the layers of granulosa cells split apart to form the antrum, the mass of granulosa cells which continue to surround the oocyte is called the "egg-bearing hill" or cumulus oophorus.
