These vessels withtheir sheaths form an important lateral attachment, which will opposedescent of the uterus. Further, at this level is to be found a well-formed band of fibrous tissue which has been named the transverseligament of the cervix (Paterson). It follows the line of the uterine 566 GYNECOLOGY vessels, but at a lower level, and is continuous with their fibrousinvestment ; it is continuous externally with the fibrous sheath ofthe iliac vessels, and with strong fibrous bands which enter the pelvisthrough the sciatic notch ; internally it is attached to the sides ofthe uterus, to the sides of the vaginal vault and to the sides ofthe urethra and bladder. It has been frequently pointed out thatin removing the uterus per vaginam the cervix cannot be pulled downmuch below its normal level until the structures at its sides havebeen divided, when it comes down easily outside the vulva.

It is possiblethat abnormal increases in intra-abdominal pressure may lead tocompensatory hypertrophy of these muscles. On the other hand,inj
