1. The massive cup-shaped ring of bone, with its ligaments, at the lower end of the trunk, formed of the innominate bone or os coxae (the public bone, ilium, and ischium) on either side and in front, and the fifth lumbar vertebra, sacrum, and coccyx posteriorly. 2. Any basin-like or cup-shaped cavity, as the pelvis of the kidney.

The part of the trunk which bounds the abdomen below. It is a large, bony, irregular, conoidal cavity,-open above and below,-which supports and contains a part of the intestines, and the urinary and genital organs; and serves, at the same time, as a fixed point for the articulation of the lower limbs, the attachment of their muscles, and the execution of their movements. The pelvis supports, behind, the vertebral column, and is sustained, before, by the ossa femorum. It is situate, in the adult, near the middle part of the body, and is composed of four broad, flat, unequally thick bones, differing much in their shape, size, and arrangement, which touch, are articulated at some part of their surface, and intimately united by means of a number of ligamentous fasciae. Of these bones, two are behind, on the median line,-the sacrum and the coccyx; the two others are before and at the sides, - the ilia. They are fellows, and unite, before, with each other. The most important parts of the pelvis, in an obstetrical point of view, are the brim and the outlet. The BRIM, Augustia abdominalis, Introitus, Apertura pelvis superior, Upper Opening or strait of the Cavity of the Pelvis, (F.) Detroit superieur, D. abdominal, is the narrow part which separates the greater pelvis from the less-the false from the true, Pelvis vera seu minor. In the well-formed woman it is elliptical, and slightly inclined forwards. Its antero-posterior, sacro-pubic or conjugate diameter, in a standard pelvis, measures 41/2 inches, but with the soft parts, 3 5/8 inches; its transverse or iliac or lateral, 5 1/4 inches, but with the soft parts 4 inches; and is oblique, Diameter of Deventer, with the soft parts, 4 5/8 inches. The OUTLET, Exitus, Inferior opening or strait, Angustia perinaealis, (F.) Detroit inferieur, D. perineal, forms the lower aperture of the pelvis. The antero-posterior diameter is here, on account of the mobility of the coccyx, 5 inches: the lateral, 4 inches. The Axis OF THE PELVIS is important to be known in obstetrics. The Axis of the Brim is indicated by a straight line drawn from the umbilicus to the apex of the coccyx ;-the Axis of the Outlet by a line drawn from the first bone of the sacrum to the entrance of the vagina. An imaginary curved line which indicates the direction of the canal of the pelvis, has occasionally been termed the curve of Carus, in consequence of its having been pointedly described by the German obstetrician.

The cavity included within these bones. It is divided into a false, or superior, p., and a true, or inferior, p., by a plane passing through the promontory of the sacrum, the iliopectineal line, and the upper border of the symphysis pubis, the circumference of this plane constituting the inlet of the true p. The lower margin of the true p. is formed by the coccyx, the tuberosities of the ischia, the ascending rami of the ischia, the descending rami of the ossa pubis, and the sacrosciatic ligaments. In the female all its diameters are slightly greater than in the male.
