Graafian follicle consists of:
Graafian follicle consists of:
Open in App
Solution
The correct option is C Theca externa and theca interna
As the secondary follicle expands, the stromal cells surrounding the membrane granulosa become condensed to form a covering called the theca interna. The cells of theca interna (thecal cells) afterwards secrete a hormone called oestrogen. Outside the theca interna some fibrous tissue become condensed to form another covering called the theca externa.
Corpus luteum is formed after ovulation. The ruptured Graafian follicle transforms into the corpus luteum. The Corpus luteum is important to maintain pregnancy. It releases progesterone, which is required for the maintenance of the endometrium during implantation and later events in pregnancy.
The corpus albicans, is a scar on the surface of the ovary that is a remnant of ovulation.
Oogonia are female gamete mother cells, which are diploid cells. They are formed from primitive germ cells. They produce eggs by oogenesis.
