What connects the apex of the bladder to the umbilicus?

The structure that connects the apex of the bladder to the umbilicus is the urachus. The urachus is a fibrous cord that is a remnant of the allantois, which is present during fetal development. It connects the bladder to the umbilicus, serving a crucial role in the development of the urinary system in the fetus. After birth, this structure typically becomes a cord-like structure known as the median umbilical ligament, but it originally serves to connect these two points.

In adults, the urachus is usually obliterated and forms the median umbilical ligament, highlighting its developmental significance. Although the median umbilical ligament is indeed associated with the apex of the bladder, it is essential to understand that the direct developmental connection during fetal life is through the urachus. Therefore, the correct answer centers on the urachus, not the median umbilical ligament.

Understanding these anatomical connections is crucial for health professionals, especially when discussing conditions or procedures involving the bladder and the umbilical area.
