Question

During ovulation, the ovary releases

• A. Oogonia
• B. Ootid
• C. Primary oocyyte
• D. Secondary oocyte

Answer 1

The correct option is D Secondary oocyte

In humans, oocyte development occurs in the ovaries. Each oocyte is surrounded by a number of follicle cells to create a follicle. When the menstrual cycle begins one, or maybe even a few, primary oocytes begin to grow larger and the follicle cells increase in number and cause the follicle to grow larger too. As a follicle reaches maturity, the primary oocyte completes its first meiotic division and becomes a secondary oocyte. Very soon after that, the follicle ruptures, and the secondary oocyte is released into the fallopian or uterine tube. The release of a secondary oocyte from the ovaries is called ovulation.
