Apex of urinary bladder

The apex of urinary bladder (vertex in older texts) is directed forward toward the upper part of the pubic symphysis, and from it the middle umbilical ligament is continued upward on the back of the anterior abdominal wall to the umbilicus. The peritoneum is carried by it from the vertex of the bladder on to the abdominal wall to form the middle umbilical fold.
