    • Theca folliculi

    Secondary (or vesicular) follicles:

    • Oocyte (primary)
    • Zona pellucida
    • Zona granulosa
    • Follicular antrum
    • Cumulus oophorus
    • Theca interna
    • Theca externa

    Mature or Graafian follicle:

    • Oocyte (secondary)
    • Zona pellucida
    • Zona granulosa
    • Corona radiata
