Pelvis vessels Flashcards
what is the main arterial supply of the pelvis
internal iliac artery
the aorta divides to give what
common iliac arteries
where does the aorta bifurcate
L4
each common iliac divides to give
an external and an internal iliac artery
what do the external and internal iliac arteries supply
external goes to lower limb
internal goes to pelvis
the internal iliac artery further divides to what
anterior and posterior division (although there is variation)
what are the typical branches of the anterior division of the internal iliac
umbilical artery obturator artery inferior vesical middle rectal inferior gluteal internal pudendal
describe the path of the umbilical artery
branch of the anterior division of the internal iliac artery - ends as a piece of connective tissue but before that point it gives off at least 2 branches to supply the bladder; the superior vesical arteries
the obturator artery passes through the _____ foramen into the _____ compartment of the thigh
obturator
medial compartment of the thigh
what is a variation associated with the obturator artery
this vessel may be absent and instead a small vessel crosses the superior ramus of the pubic bone from the femoral or external iliac arteries to then enter the pelvis and pass through the obturator foramen
in the female, what usually replaces the inferior vesical artery
vaginal or uterine artery
what vessel supplies the rectum in both sexes
middle rectal artery
the middle rectal artery supplies what in males
rectum and prostate
what vessel supplies the gluteal region with blood
inferior gluteal artery
describe the path of the inferior gluteal artery
branch of anterior division of the internal iliac artery
passes through the greater sciatic notch to supply the gluteal region
what is the final branch of the anterior division of the internal iliac artery
internal pudendal artery
what branches does the internal pudendal artery give off
inferior rectal branch in the anal triangle and several branches to the perineum
in males, the inferior vesical and middle rectal arteries supply what
prostate, seminal vesicles and ductus deferens
in males what artery supplies the testes
testicular arteries from abdominal aorta at L2
in females what artery supplies the ovaries
ovarian arteries from the abdominal aorta at L2
in females, the inferior vesical artery is replaced by vaginal or uterine branches that also supply…
the bladder
the distal parts of the vagina are supplied with blood by what
perineal branches of the internal pudendal artery
what are the branches of the posterior division of the internal iliac artery
iliolumbar
lateral sacral
superior gluteal
the iliolumbar artery supplies what
part of the posterior abdominal wall
the lateral sacral artery contributes blood to the
vertebral canal
the superior gluteal artery supplies
part of the gluteal region
the obturator artery originates from
internal iliac (anterior)
the obturator artery supplies
pelvic muscles, head of femur, ilium
the superior vesical artery originates from
umbilical artery
the superior vesical artery supplies
superior aspect of baldder and ductus deferens
the ductus deferens artery originates from where
superior/inferior vesical artery
the ductus deferens artery supplies
ductus deferens
the inferior vesical artery originates
internal iliac (anterior)
the inferior vesical artery supplies
urinary bladder, ureter, seminal vesicle, prostate
the middle rectal artery originates
internal iliac (anterior)
the middle rectal artery supplies
rectum
seminal vesicle
prostate
the internal pudendal artery originates
internal iliac (anterior)
the internal pudendal supplies
perineum and anal canal
the inferior gluteal artery originates
internal iliac (anterior)
the inferior gluteal artery supplies
levator ani
coccygeus
piriformis
gluteal region
the uterine artery originates
internal iliac
the uterine artery supplies
ureter
uterus
vagina
the vaginal artery originates
uterine artery
the vaginal artery supplies
vagina and bladder
the iliolumbar artery originates
internal iliac (posterior)
the iliolumbar artery supplies
cauda equina
iliacus
psoas
quadratus lumborum
the lateral sacral artery originates
internal iliac (posterior)
the lateral sacral artery supplies
vertebral canal
piriformis
the superior gluteal artery originates
internal iliac (posterior)
the superior gluteal artery supplies
levator ani
piriformis
gluteal region
what is the venous drainage of the pelvis
equivalent veins to arteries that mainly drain into the internal iliac veins, also small venous plexuses associated with some of the pelvic structures e.g. prostate gland, rectum and sacrum
