Ureters and Urinary Bladder Flashcards
describe the course of the ureter
- the ureter commences as a dilatation called the renal pelvis, which lies posterior to the renal vessels, and as it descends it lies on the psoas major muscle.
- it crosses anterior to the bifurcation of the common iliac artery, courses along the lateral walls of the pelvis, and turns medially to reach the bladder.
in males, which structure crosses the ureter superiorly?
ductus (vas) deferens
in the female, which structure crosses the ureter superiorly?
uterine artery
list the three constrictions in the ureters where calculi (stones) may lodge
- ureteropelvic junction
- pelvic brim
- ureterobladder junction
label the male urinary bladder
which part of the bladder do the ureters enter?
fundus
from which part of the bladder does the urethra exit?
neck
The apex of the urinary bladder is the site from which the median umbilical ligament ascends to the umbilicus. Embryologically, what is this a remnant of?
metanephric mesoderm
which of the 4 tissue types makes up the walls of the urinary bladder?
smooth muscle
identify the bony joint immediately anterior to the urinary bladder
pubic symphysis
There is a large variety in the bladder size seen on cadaveric specimens. The bladder can be sufficiently enlarged to reach into the abdominal cavity. In males what could be the cause of the enlarged bladder?
prostate enlargment or kidney stones
label the hemisected female pelvis
label the hemisected male pelvis

ureter
this is the lining of which structure?
bladder
