### Follicle Development

#### Left Image: Secondary Follicle
The diagram illustrates a secondary follicle. Key structures labeled in this diagram are:

- **Primary Oocyte**: The central cell within the follicle, responsible for developing into an ovum.
- **Antrum**: A fluid-filled cavity within the follicle.
- **Granulosa Cells**: Cells that surround the primary oocyte, providing nutrients and hormonal support.

#### Right Image: Graafian (Mature) Follicle
The diagram represents a Graafian or mature follicle, showcasing the following components:

- **Secondary Oocyte**: The matured oocyte, ready for ovulation.
- **Zona Pellucida**: A glycoprotein layer surrounding the oocyte.
- **Corona Radiata**: A layer of cells that encircle the zona pellucida.
- **Antrum**: The expanded fluid-filled cavity characteristic of mature follicles.
- **Granulosa Cells**: These cells continue to nourish and support the oocyte.

These diagrams highlight the structural changes and components involved in follicle maturation and ovum preparation for ovulation.
