Not illustrated. 1876 Excerpt: ...surfaces, rather than angular edges, to any object descending through the perineal strait. By these several peculiarities of form and structure, the female pelvis is adapted to permit the expansion of the uterus during pregnancy, and the passage of the child in parturition. The following table of the average comparative dimensions of the male and female pelvis, according to the various estimates of Meckel, Cloquet, and Burns, is taken from Quain's Anatomy. The joints of the female pelvis acquire an increased mobility during the last months of gestation; the symphysis pubis, and the articulations of the coccyx, are especially relaxed. This change is at first temporary, but after frequent childbearing it becomes permanent. The same cause is said to induce occasionally an actual alteration of structure. Of this a very remarkable example has been noticed by Cruveilhier, in the pelvis of an aged female, who had borne nineteen children. In this instance the articular surfaces of the symphysis pubis had come into contact, and the inferior ligament had disappeared; while a fibrous capsule of great strength surrounded the joint on all sides, except behind, and permitted a very considerable motion.
