The multi-layered mass of granulosa cells surrounding the oocyte is called?

• A. Corona radiata
• B. Cumulus oophorus
• C. Zona pellucida
• D. Theca interna

Answer: (B)

The surrounding granulosa cell mass around the oocyte is the cumulus oophorus. This cluster of granulosa cells forms a multi-layered cap that envelops and nourishes the oocyte, connecting it to the follicle wall and helping regulate its maturation. The innermost layer around the zona pellucida is called the corona radiata, which is a subset of the cumulus cells. The zona pellucida itself is the glycoprotein coat directly around the oocyte, and the theca interna is a separate layer outside the granulosa cells that contributes to hormone production. So, the multi-layered granulosa cell mass surrounding the oocyte is the cumulus oophorus.
