By the end of this section, you will be able to:
  • Describe the structure and function of the organs of the female reproductive system
  • List the steps of oogenesis
  • Describe the hormonal changes that occur during the ovarian and menstrual cycles
  • Trace the path of an oocyte from ovary to fertilization

Reproductive system module 2: the female reproductive system

The female reproductive system functions to produce gametes and reproductive hormones, just like the male reproductive system; however, it also has the additional task of supporting the developing fetus and delivering it to the outside world. Unlike its male counterpart, the female reproductive system is located primarily inside the pelvic cavity ( [link] ). Recall that the ovaries are the female gonads. The gamete they produce is called an oocyte    . We’ll discuss the production of oocytes in detail shortly. First, let’s look at some of the structures of the female reproductive system.

Female reproductive system

This figure shows the structure and the different organs in the female reproductive system. The top panel shows the lateral view and the bottom panel shows the anterior view.
The major organs of the female reproductive system are located inside the pelvic cavity.

External female genitals

The external female reproductive structures are referred to collectively as the vulva    ( [link] ). The mons pubis    is a pad of fat that is located at the anterior, over the pubic bone. After puberty, it becomes covered in pubic hair. The labia majora    (labia = “lips”; majora = “larger”) are folds of hair-covered skin that begin just posterior to the mons pubis. The thinner labia minora    (labia = “lips”; minora = “smaller”) are between the the labia majora. The labia minora serve to protect the female urethra and the entrance to the female reproductive tract.

The clitoris    (or glans clitoris) is an organ that originates from the same cells as the glans penis and has abundant nerves that make it important in sexual sensation and orgasm. The hymen    is a thin membrane that sometimes partially covers the entrance to the vagina. An intact hymen cannot be used as an indication of “virginity”; even at birth, this is only a partial membrane, as menstrual fluid and other secretions must be able to exit the body, regardless of penile–vaginal intercourse. The vaginal opening is located between the opening of the urethra and the anus. It is flanked by outlets to the Bartholin’s glands    (or greater vestibular glands).

The vulva

This figure shows the parts of the vulva. The right panel shows the external anterior view and the left panel shows the internal anteriolateral view. The major parts are labeled.
The external female genitalia are referred to collectively as the vulva.

Vagina

The vagina    , shown at the bottom of [link] and [link] , is a muscular canal (approximately 10 cm long) that serves as the entrance to the reproductive tract. It also serves as the exit from the uterus during menses and childbirth. The thin, perforated hymen can partially surround the opening to the vaginal orifice. The hymen can be ruptured with strenuous physical exercise, penile–vaginal intercourse, and childbirth. The Bartholin’s glands    and the lesser vestibular glands (located near the clitoris) secrete mucus, which keeps the vestibular area moist.

Ovaries

The ovaries    are the female gonads (see [link] ). Paired ovals, they are each about 2 to 3 cm in length, about the size of an almond. The ovaries are located within the pelvic cavity, and are supported by the mesovarium , an extension of the peritoneum that connects the ovaries to the broad ligament    . Extending from the mesovarium itself is the suspensory ligament that contains the ovarian blood and lymph vessels. Finally, the ovary itself is attached to the uterus via the ovarian ligament .

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
