Final Answer:
The median umbilical ligament attaches to the apex of the bladder.
Therefore, the correct answer is:A) Apex
Step-by-step explanation:
The median umbilical ligament is a fibrous cord that is a remnant of a fetal structure known as the urachus. The urachus connects the fetal bladder to the umbilicus during development. As the urachus degenerates after birth, it forms the median umbilical ligament in adults.
The median umbilical ligament extends from the apex (top) of the bladder to the umbilicus. It represents the remnant of the tube that allowed fetal urine to pass from the bladder to the placenta for excretion. In adults, this ligament serves no functional purpose but remains as a visible anatomical feature on the anterior surface of the bladder.
