Woman Internal Sex Organs

 

The Fallopian Tubes. The Fallopian tubes (so called from Fallopius, a great anatomist, who discovered them; also called oviducts: egg conductors, because they conduct the eggs from the ovary into the uterus) are two very thin tubes, extending one from each upper angle of the womb to the ovaries; but at their ovarian end they expand into a fringed and trumpet-shaped extremity. The fringes are referred to as fimbria. They are about five inches long and only about one-sixteenth of an inch in diameter; the function of the tubes is to catch the ova as they burst forth from the ovaries and to convey them to the uterus. Taking into consideration the very narrow lumen, or caliber, of the Fallopian tubes, it is easy to understand why even a very slight inflammation is apt to clog them up, to seal their mouths or openings, thus rendering the woman sterile, or incapable of having children. For, if the Fallopian tubes are "clogged" up, the eggs, or ova, have no way of reaching the uterus.


The Greek name for the Fallopian tube is salpinx (salpinx in Greek means tube). An inflammation of the Fallopian tube is therefore called salpingitis. (A salpingitis has the same effect in causing sterility in the female as has an epididymitis in the male.) Salpingectomy is the cutting away of the whole or of a piece of the Fallopian tube (corresponds to vasectomy in the male).

The Uterus. The uterus or womb is the organ in which the fertilized ovum, or egg, grows and develops into a child. It is a hollow muscular organ, about the size of a pear, with thick walls, capable under the influence of pregnancy of great expansion and growth. The broad part of the pear is called the body of the uterus; the lower narrow part is called the neck of the uterus, or cervix. The uterus in the adult girl or woman is about three inches long, two inches broad in its upper part and nearly an inch thick. It weighs from an ounce to an ounce and a half. When the uterus is in a pregnant condition, it increases enormously, both in size and in weight, as we will see in a future chapter. The cavity of the uterus is somewhat triangular in shape; at each upper angle is the small opening communicating with the Fallopian tube; the upper portion of the uterus is called the fundus; the external opening of the womb, situated in the center of the cervix, is called the mouth of the womb, or the os, or external os.

The uterus is situated in the center of the pelvis, between the bladder and the rectum. It is supported by certain ligaments, the chief of which are the broad ligaments; but, on account of general weakness, too hard physical labor, or lifting heavy weights, the ligaments may stretch, and the uterus may sink down low in the vagina, and we then have the condition known as prolapse of the womb. Or, the womb may turn forward, when we have a condition of anteversion.

 If the womb is bent (or flexed) forward on itself the condition is called anteflexion. If the womb is turned backwards, the condition is called retroversion; if it is bent or flexed backward upon itself the condition is called retroflexion. An extreme degree of anteversion or anteflexion, or retroversion or retroflexion, may interfere with impregnation, as the spermatozoa may find it difficult or impossible to reach the opening of the womb—the external os.

 

The entire cavity of the uterus is lined by a mucous membrane;[1] this mucous membrane is called the endometrium (endo—within; metra—uterus). An inflammation of the endometrium is called endometritis. It is the endometrium that is principally concerned in menstruation—that is, it is from it that the monthly discharge of blood comes.
