In an antral follicle, the cells that encircle the zona pellucida are primarily the **Corona Radiata**. The corona radiata is a layer of granulosa cells that surrounds the oocyte and is crucial for its nourishment and protection during the final stages of follicular development and ovulation.
Here’s a brief overview of the other cell types mentioned:
- **Thecal Cells**: These cells are located in the outer layer of the follicle and are involved in the production of androgens, which are precursors to estrogen.
- **Granulosa Cells**: These are the cells that make up the bulk of the follicle, surrounding the oocyte and the zona pellucida. Granulosa cells support the oocyte and play a key role in follicular maturation and hormone production.
- **Cumulus Oophorus**: This is the cluster of granulosa cells that directly serves the oocyte and is located within the antrum, but it is specifically the portion that comes into contact with the oocyte and helps maintain its health.
In summary, the **Corona Radiata** refers specifically to the layer of granulosa cells immediately adjacent to the zona pellucida encircling the oocyte in an antral follicle.
