Flashcards in Anatomy of Lower Renal Tract Deck (34):
What is the false pelvis?
from iliac crests to pelvic inlets
What is the true pelvis?
from pelvic inlet to pelvic floor
Where is the bladder?
What are the pelvic floor muscles?
What does the urethra pass through to get to the perineum
What is the pelvic floor formed from?
bowl shaped pelvic diaphragm
What is the perineum?
perineum is shallow compartment
between pelvic floor and skin
Do the ureters pass posterior or anterior to the common iliac vessels to enter the pelvis?
What happens to the ureters at the level of the ischial spine?
they turn medially to enter the posterior aspect of the bladder
Is the route of the pelvic ureter completely “sub”peritoneal?
Why do the ureters enter the posterior bladder wall in an inferomedial direction?
helps prevent reflux of urine back into the ureters when the bladder contracts
In females the ureter enters bladder how?
by passing under the uterine artery
“water under the bridge”
The uterine artery is a branch of what?
What does the internal iliac give branches to?
pelvic organs, gluteal region and perineum
What is the trigone in the bladder?
triangle shape on internal aspect
2 ureteric orifices
internal urethral orifice
The bladder wall is formed mainly by what?
What happens to the detrusor muscle when the bladder contracts to prevent reflux of urine?
fibres encircle ureteric orifices & tighten
What does the detrusor muscle forms around neck of male bladder?
internal urethral sphincter muscle
When does the internal urethral sphincter muscle contract?
contracts during ejaculation to prevent retrograde ejaculation
In the female, the body of uterus usually lies superior to the bladder in what position?
What separates the body of the uterus from the bladder?
What takes the weight of the uterus?
Where does the prostate gland lie in relation to the bladder?
What kind of bladder extends out of the pelvis?
a full one
What are the 2 routes of catheterizing a patient's bladder?
urethral (more common)
suprapubic (through anterior abdominal wall, avoiding peritoneal cavity)
How long is the female urethra?
Is the external urethral sphincter voluntary?
How long is the male urethra?
What sac do the testis sit in?
Where can the epididymis be palpated?
at posterior aspect of testis
Where can the vas deferens be palpated?
within the spermatic cord
What is posterior and transmits the deep arteries of penis?
What is anterior and transmits the spongy urethra of penis? What does it expand distally to form?
expands distally to forms the glans
