A high-power view of a section of a maturing
secondary follicle shows a large fluid-filled
antrum. The developing antrum separates the
primary oocyte from the majority of granulosa
cells. Those granulosa cells adherent to the
zona pellucida form the corona radiata. The
primary oocyte and corona radiata rest on a
mound of granulosa cells called cumulus
oophorus.
Comment
At ovulation, the oocyte and corona
radiata are expelled together. The corona
radiata consists of granulosa cells whose
microvilli penetrate the zona
pellucida and form gap junctions with oocyte
microvilli.
