A.VERIFIED ANSWERfact-checked by tutors
The diagram shows the structure of a mature Graafian follicle inside the ovary, including the ovum, follicular fluid, granulosa cells, and theca layers.
- Membrana granulosa cells: Cell layer lining the follicle
- Theca interna: Inner theca layer that helps produce hormones
- Loose connective tissue: Supporting tissue around the follicle
- Corona radiata granulosa cells: Cells surrounding the ovum
- Basal lamina: Thin layer separating granulosa cells from theca cells
- Theca interstitial cells: Hormone-producing cells in the theca layer
- Antrum: Fluid-filled cavity of the follicle
- Follicular fluid: Fluid inside the antrum
- Capillaries: Small blood vessels
- Zona pellucida: Protective layer around the ovum
- Cumulus oophorus granulosa cells: Cells that attach the ovum to the follicle wall
- Theca externa: Outer supportive layer of the follicle
