Part 2

The sex organs of the woman are divided into two classes, as follows: (1) The external organs; and (2) the internal organs. Let us consider each of these classes in turn.

THE EXTERNAL SEX ORGANS OF THE WOMAN.

The external sex organs of the woman are as follows: The Mons Veneris; the Labia Majora; the Labia Minora; the Clitoris; the Meatus Urinarius; and the Vaginal Orifice. The term "the Vulva" is applied to the external sex organs of the woman in general, but more particularly to the Labia Majora and the Labia Minora (the larger and smaller "lips," respectively). The term "Vulva" is the Latin term meaning "folding doors."

THE MONS VENERIS is the fatty eminence or elevation just above the other external organs, which forms a mount from which its name (literally, "The Mount of Venus") is derived. At puberty it becomes covered with hair.

THE LABIA MAJORA are the large "outer lips" or folds of skin which enclose the Vaginal Orifice, and which are situated just below the Mons Veneris.

THE LABIA MINORA are the small "inner lips" of folds of membrane, which are concealed within the Labia Majora, or "outer lips," and are seen only when the latter are parted.

THE CLITORIS is a small organ, about an inch in length, situated at the upper part of the Labia Minora or "inner lips," and usually being partly or wholly covered by the upper borders thereof. At its extremity it has a small rounded enlargement which is extremely sensitive and excitable, and which is the principal seat of sensation in the woman's sexual organism.

THE MEATUS URINARIUS is the orifice of the urethra of the woman, the purpose of which is to afford an exit for the urine. It is located about an inch below the Clitoris and is just above the Vaginal Orifice. It is a common error among uninformed women that the urine passes out through the Vagina; but this, of course, is incorrect, as the two canals and their respective orifices are entirely separate from each other, though situated closely together.

THE VAGINAL ORIFICE is the outer entrance to the Vagina, or Vaginal Canal or Channel. This orifice is located just below the Meatus Urinarius. In the virgin it is usually partly closed by what is known as "THE HYMEN," (vulgarly known as the "maiden head"), although in many cases the latter is absent even in the case of young girl infants. It was formerly regarded as an infallible sign of virginity, and its absence was regarded as a proof that virginity was lacking. But this old superstition is passing away, for science has shown that the Hymen is often absent even in the case of young children and infants, and, on the other hand, is sometimes present after several years of married life, and even during pregnancy. Much unhappiness has been caused in some cases where the husband has doubted the virginity of his wife because of the absence of the Hymen, but consultation with a capable physician usually removes this misunderstanding.

The Hymen is a membranous fold, sometimes circular in shape, with an opening in the center, though in other cases it extends only across the lower part of the orifice. The opening in the center is for the purpose of allowing the menstrual blood and the other secretions of Uterus and Vagina to flow through. In a few cases this opening is absent, the Hymen being what is called "imperforate"; in which case the girl experiences difficulty when menstruation begins, and a physician is required to make a slit or opening in it. In some girls and women the Hymen is quite tough, while in others it is very thin and is easily broken. In the latter cases the young girl frequently breaks the membrane during vigorous exercise, such as jumping rope, etc. And, as has before been said, in some cases infant girls are born without even a trace of the Hymen. Under the circumstances, it is seen that the presence or absence of the Hymen is far from being an infallible proof of the presence or absence of virginity, and the belief in the same is now regarded as almost a superstition of the past.

THE INTERNAL SEX ORGANS OF THE WOMAN.

The internal sex organs of the woman are as follows: The Vagina; the Uterus and its appendages; the Fallopian Tubes; the Ovaries, and their ligaments, and the round ligaments.

THE VAGINA is the canal or channel leading from the Vaginal Orifice to the Uterus or womb. It is situated in front of the rectum, and behind the bladder. In length, it averages from three to five inches; and it curves upward and backward, reaching to the lower part of the neck of the womb, or Uterus, which part of the neck is enclosed by it. It is a strong fibro-muscular structure, lined with mucous membrane; and is not smooth inside, but is arranged in inner folds or rings which are capable of great extension.

On either side of the Vagina, near the outer orifice, are two small glands, about the size of a pea, which secrete a peculiar fluid, and which are known as the Glands of Bartholine. The office of the Vagina is that of a complementary to the male organ during the copulative process; to also sustain the weight of the Uterus; to also afford a passage for the infant at the time of its birth; and also to serve as a passage for the menstrual fluid.

THE UTERUS, or Womb, is the internal sex organ of the woman which serves to hold the fertilized ovum, or egg, from the time of impregnation, during the period of pregnancy during which the ovum develops into the young child, and until the time of the delivery of the child.

The Uterus is a hollow pear-shaped muscular organ, about three inches in length, nearly an inch thick, and about two inches broad across its upper part, or FUNDUS; the lower part, or CERVIX, being much narrower. The CERVIX, or "neck" of the womb, projects into the Vagina, forming the "os uteri," or "mouth of the womb," at that point. The Uterus is composed chiefly of a muscular coat, its walls consisting of strong muscular fibres which contract independently of the will, as do similar muscles in the stomach and bladder. These muscular walls are capable of enormous distention during pregnancy. The muscles of the healthy womb are capable of a tremendous pressure and resistance, and are capable of expelling the child with but slight labor at the time of delivery.

The Uterus is located just behind and slightly above the bladder, and is supported by eight ligaments which, in a healthy condition, hold it firmly and easily in place. Displacements of the Uterus are due to the weakening or relaxing of some or all of these ligaments, generally caused by general weakness or else by excessive physical exercise or labor. The principal DISPLACEMENTS OF THE UTERUS are as follows: Prolapsus, or lowering of the womb in the vagina; Antroversion, or the bending forward of the womb; Anteflexion, or the "doubling up" of the womb FORWARD on itself; Retroversion, or the bending backward of the womb; and Retroflexion, or the "doubling up" of the womb BACKWARD on itself. Extreme degrees of the last four mentioned forms of displacement often interfere with impregnation.

The internal surface of the Uterus is lined with mucous membrane thickly studded with minute hairlike cells which manifest continuous motion. This motion, in the lower part of the womb, is in the direction of the fundus or upper part of the womb; in the upper part of the womb, the motion is in the opposite direction; the purpose of these opposing movements being to carry the male elements toward that portion of the womb into which the Fallopian Tubes discharge the products of the Ovaries, as we shall see presently.

The Uterus is supplied with follicles around its neck which secrete a very firm, adhesive mucus substance, which serves as a gate or door across the mouth of the womb during the period of pregnancy, and which also serves to prevent the accidental displacement of the ovum or egg. During and just after menstruation, the Uterus becomes enlarged and more vascular. During pregnancy, it largely increases in weight. After delivery, it resumes its normal size, but the cavity is larger than before conception. In old age, it becomes atrophied and denser in structure.

THE FALLOPIAN TUBES are the ducts of the Ovaries, and serve to convey the ova, or eggs, from the Ovaries to the cavity in the Uterus. They are two in number, one on each side, each tube being about four inches in length. They extend from either side of the fundus of the womb, through the broad ligaments which hold them and the Ovaries in position until they communicate with the Ovaries. They are lined with a membrane composed of the same kind of peculiar hair-like cells which are found in the lining of the womb, the purpose in this case being to urge forward the ova or eggs toward the Uterus.

At the ovarian end of the tubes the latter expand into a fringed, trumpet-shaped extremity, the fringe being known as "the fimbria." The tubes are only about one-sixteenth of an inch in diameter, and their small caliber makes it easy for them to clog up as the result of slight inflammation, or to become clogged up or sealed at their mouths or openings, thus causing sterility or inability of the woman to conceive. If the tubes are clogged, or sealed up, it of course is impossible for the ova or eggs to reach the uterus.

THE OVARIES are the two oval-shaped bodies lying one on either side of the Uterus. In them the ova, or eggs, are formed. They are each about one and one-half inches long, about one inch wide, and about one-half an inch thick. In addition to their attachment to the broad ligament, they are held in position by folds or ligaments running to the fundus of the Uterus and to the fimbriated extremities of the Fallopian Tubes. The Ovaries are covered by a dense, firm coating which encloses a soft fibrous tissue, abundantly supplied with blood-vessels, which is called the stroma. Imbedded in the mesh-like tissue of the stroma are found numerous small, round, transparent vesicles, in various stages of development, known as the Graafian follicles, which are lined with a layer of peculiar granular cells. These Graafian follicles are the receptacles or sacs which contain the ova, or eggs, which constitute the female reproductive germ. Each vesicle contains a single ovum or egg.

Summary.

From the foregoing, it is seen that we may enumerate the sex organs of the woman as follows, proceeding from the external to the internal organism: First, the Mons Veneris, or prominent eminence above the more important external sex organs; then the Labia Majora, or large outer "lips" or folds, which are plainly discernable to the ordinary view; then the Labia Minora, or smaller inner "lips" or folds, and the Clitoris or small sensitive organ, and the Meatus Urinarius or urinary orifice, all of which are discernable only when the folds of the Labia Majora are parted or opened. Then, proceeding upward and backward from the Vaginal Orifice, we find the Vagina, or channel or canal leading to the Uterus or Womb; then we find the Uterus or Womb at the upper end of the canal or channel of the Vagina. Then extending from either side of the Uterus or Womb we find those two important sets of organs known as the Fallopian Tubes, and the Ovaries, respectively. The Ovaries discharge their ova, or eggs, into the Fallopian Tubes, from whence they are conveyed to the Uterus or Womb, with which the tubes are connected and into which they open at its upper and large end.

THE PELVIS is that bony arch in the cavity of which are contained the internal sex organs of the woman. The Pelvis is a bony basin which holds and supports the pelvic organs, and is composed of three important parts, as follows: (1) The Sacrum, consisting of five sections of the vertebral column, or spine, fused together so as to constitute the solid part of the lower spine and the back of the Pelvis; (2) the two Hip-Bones, one on each side of the Pelvis; (3) the Pubic Arch, or the front part of the Pelvis, formed by the junction of the two Hip-Bones in front. Attached to the Hip-Bones are the thighs, and also the large Gluteal Muscles which constitute the buttocks, or "seat."

The Pelvis of the woman is quite different from that of the man. It is shallower and wider, and lighter in structure than that of the male, and the margins of the Hip-Bones are more widely separated, thus making the hips of the woman far more prominent than those of the man. Also, the Sacrum is shorter than that of the man, and the Pubic Arch wider and more rounded than his. This difference in the bony structure is made necessary by the demand for larger space in the female Pelvis required for the purposes of childbirth. These differences are not so perceptible in childhood, but become marked and pronounced at puberty.

LESSON III

PHYSIOLOGY OF THE FEMALE SEX ORGANISM

In the preceding lesson you have been shown "just what" each one of the sex organs of the woman IS. In the present lesson you will be shown "just what" each of these organs DOES--what its functions and offices are. The preceding lesson dealt with the ANATOMY of these organs; the present lesson will deal with the PHYSIOLOGY thereof.

Beginning with the Ovaries, the fundamental and basic sex organs of the woman, you will have explained to you the wonderful processes performed by each of these organs in turn.

THE OVARIES. The Ovaries in the woman are akin to the testicles in the man. Without the Ovaries there would be no ova or eggs, and without the ova there would be possible no reproductive purposes, and therefore no office for the sex organs at all, for reproduction is the fundamental office, function, and purpose of the entire sexual organism.

In our consideration of the office, purposes, and functions of the Ovaries, however, we must not overlook a certain secondary phase of such functioning. While it is true that the primary purpose of both the testicles of the male, and the Ovaries of the female, is that of providing SEED from which the offspring of the individual may be produced, it is likewise true that there exists a secondary purpose which may be called the "individual" purpose as contrasted with the "racial" and primary one.

This secondary or "individual" purpose of the Ovaries is that of manufacturing certain secretions which are absorbed by the blood of the woman, and which play an important part in her physical and mental well-being and activities. These secretions begin before puberty in the woman, and continue after her menopause; whereas the manufacture of the ova begins only at puberty, and ceases with the menopause, keeping pace with the manifestation of menstruation in its beginning and its ending.

Nature provides these chemical secretions from the Ovaries for the purpose of giving the woman her characteristic physical form and contour, her form, her breasts, her long hair, her broad pelvis, her soft voice, and other secondary sex characteristics; and also of providing for the normal development of the other sex organs. As a proof of this statement, science shows us that if a woman's ovaries are completely removed there is usually a consequent atrophy or "drying up" of the Uterus and the Vagina, and often even of the Vulva. Moreover, the presence of this internal secretion manifests in arousing and maintaining in the woman her normal sexual desire, and her normal pleasure in the company of her mate; it being noted that if the ovaries are removed, particularly in early life, the woman is apt to lose all sexual desire and normal womanly feeling toward the other sex. And, finally, these secretions make for general physical and mental health and well-being in the woman, and contribute to her vivacity, energy, and activity in all directions. As writers on the subject have well pointed out, this is the reason that capable surgeons usually try to leave at least a portion of the Ovaries when performing an operation for the removal of those organs on account of diseased condition.

THE OVUM. The Ovum, or human egg, is a small spherical body, measuring from one two-hundred-and-fortieth to one one-hundred-and-twentieth of an inch in diameter. It has a colorless transparent envelope, the latter enclosing the yolk which consists of granules or globules of various sizes embedded in a viscid fluid. In the center of the yolk is found a very small vesicular body consisting of a tenuous transparent membrane, which is known as "the germinal vesicle;" this, in turn, contains a very tiny granular structure, opaque, of yellow color, known as "the germinal spot."

When the time is reached in which the ovum or egg is to be discharged, the Graafian follicle becomes enlarged by reason of the accumulation of the fluids in its interior, and exerts such a steady and increasing pressure from within, outward, that the surrounding tissue yields to it, and it finally protrudes from the Ovary, from whence it is then expelled with a gush, owing to the elasticity and reaction of the neighboring tissues.

Following this rupture there occurs an abundant hemorrhage from the vesicles of the follicle, the cavity being filled with blood, which then coagulates and is retained in the Graafian follicle. The formation and development of the Graafian follicle begins at puberty and continues until the menopause or "change of life" of the woman. Many follicles are produced, but many do not produce ova, and so gradually atrophy. The ripening and discharge of the eggs produce a peculiar condition of congestion of the entire female sexual organism, including the Fallopian Tubes, the Uterus, the Vagina, and even of the Vulva, which results in a condition of Sexual Excitement. Among the lower animals the female will allow the male to approach her for copulation only at this period, this being the time when the egg is ready for fertilization.

When the female infant is born, her Ovaries contain the germs of about 100,000 ova. The greater portion of these, however, disappear, until at the time of her puberty the number of germs of ova contains only about 30,000 ova. This number is far more than the woman will ever need, and is Nature's provision against diseased portions of the Ovaries, accidents, etc. Only one ovum ripens and matures each month from puberty until menopause, so that the woman really requires only about 300 to 350 ova on the average. This liberality on the part of Nature, however, does not begin to approach her lavishness in the case of seed of the male, for in his case while only one spermatozoon is required to fertilize an ovum (and in fact only one is permitted to do so), we find that in each normal act of ejaculation of semen by the male over 250,000 spermatozoa are projected.

The ripening and discharge of the egg from the Ovaries, and the consequent congestion above referred to, accompanied by what is called Menstruation, occurs regularly each lunar month (28 days). What is called Ovulation consists of the monthly maturing and expulsion of the ripe ovum or egg, while Menstruation (as we shall see later on) consists of the monthly discharge of blood and mucus from the inner surface of the Uterus; the two processes occur in connection with each other, yet neither can be considered as the cause of the other.

MENSTRUATION. It may be well to call your attention at this point to the process known as Menstruation, or "the monthly flow," or "the courses" of women. Menstruation is the monthly flow of bloody fluid which occurs in all healthy (non-pregnant) women from puberty to the menopause or "change of life."

By "PUBERTY" is meant the age at which a woman begins her period of possible child-bearing experience. In temperate climates the average age of puberty is about fourteen years, while in tropical countries it is often a year or so earlier, and in arctic countries a year or so later. The time, however, depends materially upon the temperament, race, hygiene, and general environment of the individual girl. At this period the girl gradually changes into the young woman. Her figure changes, her bust develops, her hips broaden, and her mental and emotional nature undergoes a change. Also the menstrual flow begins to manifest at this time; at first scanty and irregular, but gradually changing into the characteristic flow each month.

At the period of puberty, the girl undergoes marked emotional changes. She becomes very "emotional" as a rule, and quite "sensitive." She becomes filled with strange, unaccountable longings, ideas, and "notions." She usually manifests a great emotional interest in her girl friends, and often manifests marked jealousy in connection with these friendships. The girl is apt to indulge in day-dreaming at this period, and becomes quite romantic and "flighty." She devours love stories, and delights in imagining herself as the heroine of similar adventures. The period from the beginning of puberty to that of the attainment of full sexual maturity is known as the period of "adolescence," and generally extends to about the age of eighteen in the case of girls.

By the MENOPAUSE is meant that period of the woman's "change of life," the average time of which is about the age of forty-five years, although this varies greatly in different individuals. As a rule, it is held that the period of the woman's child-bearing possibility extends over an average period of thirty years. At the Menopause the woman's reproductive activity declines and finally ends. The Ovaries diminish in size, the Graafian follicles cease to form and develop; the Fallopian Tubes atrophy; and there occur other physical, mental, and emotional changes in the woman. While the age of forty-five is held to be the average age at which the Menopause occurs in women, still it is not at all uncommon to find women who menstruate regularly up to the age of fifty, or fifty-two, or even fifty-five, while a large number of women menstruate regularly at the age of forty-eight.

Some women undergo little or no physical or emotional disturbance at the time of the Menopause. In such cases their periods become more or less irregular, with extending intervals between periods; the flow becomes more and more scanty; then several periods are skipped altogether; and finally the periods cease entirely. Other women, however, experience more or less physical disturbance during the years of the "change." They sometimes experience loss of appetite, or a capricious appetite, headaches, loss of weight, or else a sudden taking on of fatty tissue. They often become quite irritable and "notiony," and often become quarrelsome and pugnacious, and in some cases manifest unreasonable jealousy. But, in the opinion of many of the best authorities, much of this trouble comes from the mental expectancy of them by the woman, resulting from the notion that a woman must have these things happen to her. The power of the mind over the body is now well known, and we have here another instance of its effect. The remedy is obvious.
