Final answer:
The lamina propria does not surround the mucosa of the ureter.
Step-by-step explanation:
The statement 'The laminal propria surrounds the mucosa of the ureter' is false.
The lamina propria is a layer of loose connective tissue, nerves, and blood and lymphatic vessels that is found in the walls of organs such as the bladder. It is not specifically associated with the ureter. Instead, the ureter is lined with transitional epithelium and has layers of smooth muscles that help propel urine from the kidneys to the bladder.
