Woman Internal Sex Organs

 

The entire cavity of the uterus is lined by a mucous membrane; 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.

The Vagina [vagina in Latin—a sheath]. The vagina is the tube or canal which serves as a passage-way between the uterus and the outside of the body. It extends from the external genitals or vulva to the neck of the womb, embracing the latter for some distance. It is a strong, fibromuscular canal, lined with mucous membrane. It is not smooth inside, but arranged in folds, or rugæ, so that when necessary, as during childbirth, it can stretch enormously and permit the passage of a child's head. The length of the vaginal canal is between three and five inches, but it is in general much more capacious in women that have borne one or more children than in those who have not borne any.

Near the vaginal entrance are situated two small glands; they are about the size of a pea, and secrete mucus. They are called Bartholin's glands; occasionally they become inflamed and give a good deal of trouble.


The Hymen [hymen in Greek—a membrane]. The external opening of the vagina, in virgins, that is, in girls or women who have not had sexual intercourse, is almost entirely closed by a membrane called the hymen. The vulgar name for hymen is "maidenhead." The hymen may be of various shapes, and of different consistency. In some girls it is a very thin membrane, which tears very readily; in others it is quite tough. On the upper margin or in the center of the hymen there is an opening which permits any secretion from the vagina and the blood from the uterus to come through. In rare cases there is no opening in the hymen, that is, the vagina is entirely closed. Such a hymen is called imperforate (not perforated).

When the girl begins to menstruate, the blood cannot come out and it accumulates in the vagina. In such cases the hymen must be opened or slit by a doctor. In some cases the hymen is congenitally absent; that is, the girl is born without any hymen. While the hymen is usually ruptured during the first intercourse, it, in some cases, being elastic and stretchable, persists untorn after sexual intercourse. It will therefore be seen that just as the presence of the hymen is no absolute proof of [42]virginity, so is the absence of the hymen no absolute proof that the girl has had sexual relations, She might have been born without any hymen, or it might have been ruptured by vaginal examination, by a vaginal douche, by scratching to relieve itching, or by some accident.

The remains of the hymen after it is ruptured shrink and form little elevations which can be easily felt; they are known as caruncles. [In Latin, carunculæ myrtiformes, which means in English myrtleberry-shaped caruncles; caruncle is a small fleshy elevation; derived from caro, which in Latin means flesh.]
