Which of the following choices best describes ‘ovulation?'
A. An egg is released from the ovary.
B. An embryo sinks into the uterus lining.
C. The sperm and egg nuclei fuse.
D. The ejection of sperm through the penis.

Answers

Answer:

An egg is released from the ovary

Ovulation is a crucial process in the female reproductive system, occurring as a part of the menstrual cycle. It involves the release of a mature egg (ovum) from one of the ovaries. The correct option is A. An egg is released from the ovary.

1. **Menstrual Cycle**: The menstrual cycle is the regular hormonal cycle that occurs in women of reproductive age. It typically lasts around 28 days, although the length can vary from woman to woman. The cycle is divided into different phases, with ovulation occurring during one specific phase.

2. **Follicular Phase**: The menstrual cycle begins with the follicular phase, where hormones, primarily follicle-stimulating hormone (FSH) and luteinizing hormone (LH), are released by the pituitary gland. These hormones stimulate the growth and maturation of follicles in the ovaries.

3. **Ovarian Follicles**: Within the ovaries, multiple tiny sacs called ovarian follicles contain immature eggs. Each month, one of these follicles becomes dominant and continues to grow while others degenerate.

4. **Mature Follicle Development**: As the dominant follicle grows, it secretes estrogen, a hormone that prepares the uterus for a potential pregnancy. The rising estrogen levels also trigger a surge in luteinizing hormone (LH) around the middle of the menstrual cycle.

5. **Ovulation**: The LH surge triggers the final stage of ovulation. It causes the mature follicle to rupture and release the mature egg from the ovary. The egg is swept into the fallopian tube by tiny hair-like structures called cilia.

6. **Fertilization**: The released egg remains viable for about 12-24 hours. If sexual intercourse occurs during this time and sperm are present in the fallopian tube, fertilization may occur. Fertilization is the process where the sperm penetrates the egg, resulting in the formation of a zygote (fertilized egg).

7. **Implantation or Menstruation**: If the egg is not fertilized, it will eventually disintegrate, and hormone levels will drop. This leads to the shedding of the uterine lining, causing menstruation to occur. On the other hand, if fertilization occurs, the resulting zygote will undergo several divisions and travel down the fallopian tube to the uterus, where it may implant into the uterine lining and develop into a pregnancy.

Ovulation is a crucial event in the female reproductive cycle, marking the release of a potential egg for fertilization. It is a key factor in determining fertility and the ability to conceive a child.
