Dissection of male pelvis from a lateral approach

External muscles and ligaments at neck of bladder; tendinous arch of pelvic fascia, viewed from above

The bladder and prostate have been pulled to the left to expose bands of smooth muscle alongside the neck of the bladder which form the m. pubovesicalis (24) and which continue anteriorly into the medial puboprostatic ligament (26). Laterally, the thickened part of the pelvic fascia known as the tendinous arch of the pelvic fascia (25) is seen to be attached to the prostate and neck of the bladder by the lateral puboprostatic ligament (16, upper pointer). The lateral ligament of the bladder, consisting of fibrous tissue and smooth muscle associated with the pelvic plexus and hyogastric vessels, has been removed from the specimen.
