Question

After ovulation, in a female mammal, the structure which is formed by the ruptured follicle is

• A. Corpus luteum
• B. Graafian follicle
• C. Placenta
• D. Epididymis

Answer 1

The correct option is A Corpus luteum

The corpus luteum is a temporary endocrine structure in female ovaries and is involved in the production of relatively high levels of progesterone, moderate levels of estradiol and inhibin A, and small amounts of estrogen. The corpus luteum develops from an ovarian follicle during the luteal phase of the menstrual cycle or oestrous cycle, following the release of a secondary oocyte from the follicle during ovulation. The follicle first forms a corpus hemorrhagicum before it becomes a corpus luteum, but the term refers to the visible collection of blood, left after rupturing of the follicle, that secretes progesterone. While the oocyte (later the zygote if fertilization occurs) traverses the Fallopian tube into the uterus, the corpus luteum remains in the ovary.

So the correct option is 'corpus luteum'.
