Where do the egg cells mature in the ovary?

Where do the egg cells mature in the ovary?

The ovaries are the site of production and periodical release of egg cells, the female gametes. In the ovaries, the developing egg cells (or oocytes) mature in the fluid-filled follicles.

Is the ovaries part of the female reproductive system?

The ovaries are a pair of ova-producing organs (that is, they produce egg cells) that maintain the health of the female reproductive system. The ovaries, like their male counterpart, the testes, are known as gonads. This simply means they are the primary reproductive organs.

Where does the female gamete in the ovaries come from?

The female gamete is called an ovum or egg. The plural is ova. Ova are produced from germline cells in the ovaries. Ovaries contain immature ova at various stages of development. Each ova is protected by a follicle. This is a fluid-filled sac which surrounds it and releases hormones.

What kind of hormones are produced in the ovaries?

The major hormones secreted by the ovaries are oestrogen and progesterone, both important hormones in the menstrual cycle. Oestrogen production dominates in the first half of the menstrual cycle before ovulation, and progesterone production dominates during the second half of the menstrual cycle when the corpus luteum has formed.

How is OVA produced in the ovaries?

Ova are produced from germline cells in the ovaries. Ovaries contain immature ova at various stages of development. Each ova is protected by a follicle. This is a fluid-filled sac which surrounds it and releases hormones. Each ovary is connected to the uterus by an oviduct (fallopian tube).

Where does the fertilizable cell develop in the ovary?

In oogenesis, only one functional fertilizable cell develops from a primary oocyte. The other three cells are polar bodies and they degenerate. An ovarian follicle consists of a developing oocyte surrounded by one or more layers of cells called follicular cells.

When do the ovaries release the egg during the menstrual cycle?

The ovaries release an egg (oocyte) at the midway point of each menstrual cycle. Usually, only a single oocyte from one ovary is released during each menstrual cycle, with each ovary taking an alternate turn in releasing an egg.
