Health knowledge : a thorough and concise knowledge of the prevention, causes, and treatments of disease, simplified for home use . om the cervix, which is the lowest part of the womb,narrower and more cylindrical than the body. The cervix pre-sents into the vagina a knob-like, rounded, lower extrenuty, inwhich is a minute opening in the middle of a central dimple onthe surface. The walls of the womb are very thick in compari-son to its internal cavity, which is practically a triangular slitplaced laterally, the anterior and posterior walls being almost incontact, and it is lined with smooth mucous membrane. Thelower part of the cavity, the cervical canal, is wider in the middlethan above and below, the mucous membrane of its walls beingthrown into a series of folds. From each side of thewomb the broad liga-ments, formed of adouble layer of peri-toneum, go out to thewalls of the pelvis. Tothem are attached theovaries, and they con-tain several important structures, including the Fallopian tubesand the muscular round ligaments, which proceed forward oneach side to the inguinal canal and end in the subcutaneous tis-. Section of the Womb. THE REPRODUCTIVE SYSTEM 917 sues; these ligaments have an important share in holding thewomb in position. The vagina is the passage, about three inches in length, di-rected downward and forward, which leads from the womb tothe exterior. Its walls are muscular and it is lined with mucousmembrane, its lower end being incompletely closed in the virginby a fold of mucous membrane termed the hymen. As the genital organs are not developed until maturity, andas the child has to pass through this bony framework, it is in-judicious for girls to many and have children before they haveattained their growth; the proper age being from nineteen totwenty-five. Menstruation is considered the sign of ovulation,although it is probable that ripened ovules are thrown off atother times during the month, and it is possible for impregnationto take place at
