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.
