it is divided into two branches, the lateral pubovesical ligament and the medial pubovesical ligament. The lateral branch extends from the neck of the bladder to the tendinous arch of the pelvic fascia. The medial pubovesical ligament arises from the neck of the bladder and is a forward continuation of the tendinous arch to the pubis. In the
