Which of the following crosses the ureter in the female as it approaches the uncontroversial junction?

The ureters are tubes made of smooth muscle that propel urine from the kidneys to the urinary bladder.

In a human adult, the ureters are usually 20–30 cm (8–12 in) long and around 3–4 mm (0.12–0.16 in) in diameter.

The ureter is lined by urothelial cells, a type of transitional epithelium, and has an additional smooth muscle layer in third closest to the bladder that assists with peristalsis.
