    its bony attachment being here interrupted, and forms thus the floor of the short canal which transmits the obturator Vessels and nerves. The upper part of the fascia is in the pelvic cavity, and is lined by peritoneum, whilst the lower part forms the outer boundary of the ischio-rectal fossa, and encases the internal pudic vessels and nerve as they pass forwards. (b) The Fascia of the Pyriformis is the continuation of the obturator fascia to the sacrum, and lies anterior to the pyri- formis and sacral plexus. Visceral Layer. The Recto-vesical Fascia is attached in front to the posterior part of the pubis, close to the obturator fascia, but having the origin of the levator ani between. Laterally it is attached to the obturator fascia along a line from the upper part of the thyroid foramen to the ischial spine, whilst behind it joins the lower part of the pyriformis fascia. From these attachments it passes downwards and inwards over the upper surface of the levator ani to the prostate, bladder and rectum, joining the fascia of the opposite side in front of the bladder, and between the bladder and the rectum, thus form- ing the floor of the pelvis. Along the attachment of the recto- vesical to the obturator fascia is a thickened band, the white line of the pelvic fascia. Processes from the recto-vesical fascia :— Pubo-prostatic ligaments or anterior true ligaments of the bladder. Narrow fasciculi, one on each side, passing from the back of the pubes to the front of the prostate and neck of the bladder. Lateral true ligaments of the bladder. This is the anterior ligament prolonged laterally, and passes to the side of the prostate, and to the side of the bladder above the vesiculae seminalis, enclosing the prostatic plexus, whilst posteriorly it is attached to the bladder between the vesiculae, and is pro- longed downwards over and enclosing them, being joined to a like process from the opposite side. Ligament of the rectum. A piece of fascia descends from the ischium and is attached to the rectum on each side. In the female the vagina receives a prolongation of the recto-vesical fascia corresponding to the prostatic sheath.
