anal of the cervix. The cavityof the body presents a triangular shape with convex borders. The twoupper angles communicate by a small opening, hardly large enough toadmit a fine bristle, with the canal of the Fallopian tubes. At thelower angle is situated the os internum, a circular orifice, large enoughto admit a uterine sound, which forms the internal anatomical limitbetween the body and the cervix. The canal of the cervix has a fusi-form shape, and is included between the internal and external orificesalready described. Its inner surface is characterized by two longitu-dinal ridges, occupying the anterior and posterior walls, from which 14 PHYSIOLOGICAL ANATOMY. branching processes extend obliquely upward, giving rise to an appear-ance which justifies the title—arbor vitce uterina. In women who have borne children, the uterus measures three inchesin length, of which nearly two inches belong to the body and one tothe cervix. There is increased convexity of the fundus.

(Sappey.) between the insertions of the Fallopian tubes measures over two inches.The width of the cervix, at its junction with the body, measures oneinch. The uterus thus assumes a pyriform shape. The cavity of theuterus loses its triangular character, and assumes a more ovoid ap-pearance. The external orifice no longer forms a smooth transversedepression, but its edges, lacerated by childbirth, communicate theimpression of a rounded, puckered surface. When a profile section is made through a perfectly healthy unim-pregnated uterus, its walls are found in actual contact. A cavity doesnot, therefore, naturally exist. The uterus is so situated in the pelvic cavity as to possess a largedegree of mobility. Its lower extremity projects, as we have seen, intothe vagina. The supra-vaginal portion of the cervix is attached anteri-orly to the walls of the bladder. That portion of the uterus w7hich ex-tends freely into the pe
