Answer 1

Cumulus ovaricus

SOLUTION

A. Membrana granulosa is a layer of granulosa cells which cover the primary oocytes and form structures known as primordial follicles.

B. Cumulus ovaricus is a cluster of cells surrounding the oocyte in Graafian follicle and even after ovulation. The inner most layer of cumulus cells give rise to Corona radiata which is adjacent to the protective layer of the ovum, the zona pellucida.

C. Theca interna is the inner layer of theca follicles.

D. Theca externa is the outer layer of theca follicles.

Hence, Corona radiata is derived from Cumulus ovaricus.

So, the correct answer is 'Cumulus ovaricus'.
