This differs from the sacro-ihac synchondroses in having an interarticu- lar substance interposed between the two osseous surfaces, in addition to the fibro-cartilage covering each of these. The joint is seciired by bands of ligament, which, for the reason abeady assigned, are stronger and more bulky externally. There is also a ligament termed the sub-pubic, which occupies the apex of the arch formed by the rami of the pubic bones. The last articulation is that between the sacrum and coccyx. In it the union is effected by an in- terposed substance analogous to that between the vertebrae, and is secured by ligaments anteriorly and posteriorly. The sacro-coccygeal joint is ca- pable of flexion and extension to a considerable extent, and is the only one in the pelvis naturally admitting of motion. In certain animals, as the cow, the other articulations become relaxed about the period of parturition; and it has been,sur- mised by some authors, but without sufficient proof, that a simdar relaxation always occurs in the human female.
