In animals, egg cells are also known as ova (singular ovum, from the latin word ovum meaning egg). The term ovule in animals is used for the young ovum of an animal. In vertebrates, ova are produced by female gonads (sexual glands) called ovaries. A number of ova are present at birth in mammals and mature via oogenesis. Disproved the longstanding dogma that all of the ova are produced before birth. Oviduct is where the egg cells are fertilized while the ovary is where the egg cells are produced and where they mature. Because the fate of an oocyte is to become fertilized and ultimately grow into a fully functioning organism, it must be ready to regulate multiple cellular and developmental processes. The oocyte, a large and complex cell, must be supplied with numerous molecules that will direct the growth of the embryo and control cellular activities. As the oocyte is a product of female gametogenesis, the maternal contribution to the oocyte and consequently the newly fertilized egg, is enormous. An egg is mature after it has undergone two separate rounds of meiosis or cell division. These rounds of cell division reduce the number of chromosomes in the nucleus of the egg from 46 chromosomes to 23 chromosomes in preparation for fertilization by the sperm. In the female reproductive system, an egg matures in either one of the two ovaries this occurs approximately every 28 days. When an egg matures in the ovary, it is then released into the. The female reproductive organ that houses and matures the egg is called the. After the release of the mature egg, it is guided by the fimbria into the. When the male sex cell which is the unites with the female sex cell, takes place. Ovulation, release of a mature egg from the female ovary the release enables the egg to be fertilized by the male sperm cells. Normally, in humans , only one egg is released at one time occasionally, two or more erupt during the menstrual cycle. Egg cells, or ova, are the cells utilized by female organisms to reproduce offspring. In contrast, the reproductive cells used by males are referred to as sperm. We always hear about how interesting mens sperm are how quick, agile and strong they are, able to traverse the long journey to the egg, but how much do we know about the other genetic half of a child the female egg? In writing this article, i came across some really interesting information about human eggs that i think we should all know. One of a pair of female organs (gonads) on each side of the pelvis.
