This is because the contractions of the bladder commence at the apex of the organ an pass towards the base. * A patent urachus because it opens into the apex of the bladder is closed temporarily during micturition and so the potential urinary system from the bladder is cut off Omphalocele - midline abdominal wall defect. When the defect is less than 4 cm it is termed a hernia of the umbilical cord; when greater than 10 cm it is termed a giant omphalocele Umbilical hernia - a fascial defect at the umbilicus less than 1cm in diameter close spontaneously by 5 years of age in 95% of cases.
