Expert Answer
In human female reproductive system, the larger ovarian follicles or the secondary follicles consist of a follicular cavity called the antrum filled with follicular fluid. As the antrum enlarges, granulosa cells arrange in a stratified manner along the basement membrane called membrana granulosa.
In the early stages of the development of the secondary follicle, the adjacent stromal cells organise into a capsule or the theca folliculi, which is separated from the membrana granulosa by the basement membrane. The theca folliculi differentiates into two layers: an inner layer, theca interna and an outer layer, theca externa. The theca interna contains enlarged stromal cells and numerous capillaries. The theca externa consist of closely packed collagen fibres and small fusiform cells.
