Ureter Flashcards
1
Q
Beginning, course, and end
A
- Retroperitoneal tubular muscular structure
- Begins in renal sinus by funnel shaped pelvis of ureter (renal pelvis)
- Pelvis of ureter is partly inside renal sinus and partly outside it where it descends along kidney medial border
- Reach its lower pole (pelvic-uretic junction at level of L2 transverse process tip)
- Become ureter proper which ends at superior lateral angle of urinary bladder trigone
