Open in App
Solution
The correct option is A Corona radiata
Each Graafian follicle contains ovum. Immediately surrounding the ovum is a layer of follicle cells, the inner zona pellucida and the outer layer of columnar cells, the corona radiata. The antrum of Graafian follicle is lined by follicle cells, which form two zones as the membrana granulosa and the cumulus oophorus.The Graafian follicle is surrounded by two connective tissue cell layers. The outer fibrous layer of the follicle is theca externa and inside this layer is theca interna.Germinal epithelium is the layer of cells covering ovary.Thus, the correct answer is (A).
