Question

In which phase of the menstrual cycle, does the formation of the yellow body take place?

• A. Luteal phase
• B. Proliferative phase
• C. Follicular phase
• D. Ovulatory phase

Answer 1

The correct option is A Luteal phase

Yellow body here refers to the corpus luteum. It is referred to as a yellow body because it contains lutein protein and carotene pigment. The formation of corpus luteum takes place from the Graafian follicle that has ruptured to release the secondary oocyte, i.e. the transformation occurs after ovulatory phase. In the ovarian cycle, ovulatory phase is succeeded by the luteal phase. The formation of a yellow body takes place in the luteal phase.
In the proliferative phase of the uterine cycle, the cells of the endometrium proliferate or multiply rapidly, thus regenerating the lost endometrial lining.
During the follicular phase of the ovarian cycle, the ovarian follicles undergo growth and development under the influence of hormones LH and FSH.
In the ovulatory phase, the Graafian follicle ruptures to release the secondary oocyte, under the influence of LH.
