Class 1 - Station 3 Flashcards
which organs of the pelvis aren’t supplied by branches of internal iliac arteries
ovaries/testes and upper part of rectum
origin of superior rectal artery
IMA
origin of gonadal artery (ovaries and testes)
abdominal aorta
artery which supplies the bladder and seminal gland and prostate in males
superior and inferior vesical
level of common iliac bifurcation
L5/S1
origin of middle and inferior rectal artieries
internal iliac
what does the vaginal artery supply and what is it a branch of
vagina and uterine artery
supply and origin of uterine artery
uterus, ureters, uterine tube and ligament, vagina
comes from internal iliac
supply and origin of obturator artery
pelvic muscles, femur head and ilium
comes from internal iliac
5 veins of pelvis
internal iliac, superior rectal, median sacral, gonadal and internal vertebral venous plexus
which part of the rectum drains into the IMV
superior 2/3
which part of the rectum drains into the systemic circulation
lower 1/3
why are haemorrhoids associated with liver cirrhosis
liver cirrhosis –> portal hypertension –> rectal varices –> haemorrhoids
what venous plexus does the prostatic venous plexus communicate with on its posterior side
internal vertebral venous plexus
clinical significance of prostatic venous drainage
spread of prostate cancer
what nerve produces the cremastic reflex
genital branch of genito-femoral nerve (L1-L2)
where does the genito-femoral nerve (L1-L2) enter the pelvis through
deep inguinal ring
structures innervated by genital branch of genito-femoral nerve (L1-L2)
scrotum and cremaster muscle
how is the cremastic reflex elliceted
lightly stroking the inner thigh
roots of pudendal nerve
S2-4
what bony landmark is palpated to find the pudendal nerve and give a nerve block
