PUBERTY. Puberty is the critical transition-period in which the child becomesthe woman. The relations and influences of this period are funda-mental, both in the reproductive organs and in the entire woman, sothat upon the normal course of it depends much of the after health,comfort, and usefulness of the individual. The Anatomical Basis of puberty is the full physical develop-ment of the reproductive organs. The infantile uterus is small, soft,and plastic; it varies in size from that of early infancy (Figure 1) tothat of the child-uterus just before puberty; at the beginning ofpuberty the uterine canal would measure, perhaps, two inches; whenfully developed at the end of puberty it should measure two and one-half inches. Figure Uterus, Fallopian tubes, and ovaries of an infant one month old. Natural size. The cervix of the infantile uterus is two-thirds, and the corpusone-third, as long as the entire organ. These proportions when theorgan is fully developed at the end of puberty are reversed—that is,the corpus represents two-thirds and the cervix only one-third of thelength of the mature uterus. At maturity the longitudinal axisextending from the os externum tc the fundus measures three inches;the transverse axis of the corpus uteri measured laterally from hornto horn is two inches, and measured by the longest anteroposteriordiameter is one inch. The fundus of the infiantile uterus is flat; thefimdus of the mature uterus is convex and dome-shaped. The mucosaof the infantile uterus presents an arhor vitce arrangement throughoutthe corpus and cervix; at maturity this arrangement is confined tothe cervix. Developmental changes simil
