Renal Anatomy 3: Ureters, Bladder and Urethra Flashcards
These arise from the renal pelvis at each hilum. They work to carry urine from the kidney to the urinary bladder.
Ureters
What is the motility pattern responsible for moving urine from ureter to urinary bladder?
Peristaltic waves
True or false. The ureters are found anterior to the abdomen, vertical from the hila.
False. Ureters are retroperitoneal
What type of epithelium are the ureters made of?
Transitional epithelium
These are structures in the inner surface of ureter that protect urine from being exposed to underlying cells.
Protein plaques
These act as a sphincter of valve in the wall of the bladder, compressed by increased bladder pressure to prevent backflow.
Ureters
True or false. Ureters run obliquely through the wall of the bladder at its posterolateral corners.
True
True or false. The trigone is a triangular region with 2 openings for the ureter and 1 opening for the urethra.
True
Describe and compare an empty bladder versus a full bladder.
Empty bladder => triangular shape, in the pelvis
Full bladder => spherical shape, extends superiorally to the abdominopelvic cavity
This is responsible for storing and expelling urine.
Urinary bladder
What is the type of epithelia found in the urinary bladder?
Transitional epithelia
What layer/s of muscle are found in the ureter?
Inner longitudinal and outer circular muscle (smooth muscle)
What layers of muscle are found in the urinary bladder?
detrusor muscle (made up of longitudinal, oblique and circular muscle fibres) (smooth muscle)
Name 3 structures that protect the urinary tract.
Protein plaques, transitional epithelium, sphincters to prevent backflow of urine
This is responsible for draining urine from the bladder out the body.
Urethra
