Anatomy of Pelvic Side Wall Flashcards
What ligaments make up the lateral pelvic wall?
sacrospinous and sacrotuberous and obturator membraen
What muscles make up the lateral pelvic wall?
levator ani; coccygeus; piriformis; obturator internus
Where do the majority of arteries of pelvis and perineum arise from?
internal iliac artery
What does the gonadal artery arise from?
abdo aorta
What level does the gonadal artery branch fro mthe aorta?
L2
What is the superior rectal artery a continuation of?
inferior mesenteric
What does internal iliac artery bifurcate into?
anterior and posteiorr divisons
What is the general rule reagrding the anterior nad posterior divisons of the internal iliac artery?
anterior- usually visceral and posteiror-usually parietal
Waht is the median umbilical ligament ?
remnant of the umbilica artery
What is the function of the umbilical arery?
connects the internal iliac to the placenta through the umbilical cord
What is the name for the inferior vesical artery in females?
vaginal artery
What vessesls arise from the anterior divison of the internal ilaic?
obturator; superior and inf. vesical arteries; internal pudendal; middle rectal
What arteries arise from the posteiror divison?
gluteal arteries
What is found within the lateral umbilical fold?
inferior epigastric vessels
What is the difference between the medial umbilical fold and the median umbilical fold?
medial umbilical fold is a remnant of hte umbilical artery whereas the median umbilical fold is derived from the urachus
What si the urachus
fibrou remnant of hte allantois, a structure which drains the urinary bladder of the fetus and drains it though the umbilical cord
What does the anteiror scrotal artery come from?
external iliac
What are the terminating branches of the internal pudendal in males?
dorsal artery and deep artery of penis
What artery is the posteiror scrotal artery a continuation of?
perineal artery
What is the uterine artery a homolog of ?
artery to the vas deferens
Which arteries in the female anastamose together?
uterine artery; vaginal artery and ovarian artery
What are the 2 branches of hte ovarian artery?
ovarian and tubal branches
What artery is the perineal artery a branch of?
internal pudendal
What artereis a continuation of the pernieal artery?
labial arteries
Waht are the terminating arteries of the internal pudendal in the female?
labial arteries and dorsal artery of clitoris
What is the main vneous draininage in the pelvis?
internal iliac vein
What is the otehr venous drainage of hte pelvis aside from the internal iliac vein?
superior rectal—hepatic portal system; lateral sacral veins–internal vertebral venous plexus
Why does ureter damage occur more on the left than the right?
right is constant and usually crosses the external ilaic whereas the left ismore medial and crosses the common iliac
Where do superior pelvic viscera generally drain lympahtics to?
external iliac nodes
Where does the inferior pelvic viscera drain its lymphatics?
internal iliac nodes
Where does lymphatics travel after the internal iliac nodes?
common iliac–aortix–thoracic duct–venous system
Where does lymph from the superificial perineum drain?
superficial inguinal nodes
Where does lymph from the clitoris and glans penis drain?
deep inguinal nodes
Where does lymph from the rest of hte penis (not glans) drain?
superifical inguinal nodes
What do nerves on the lateral wall of the pelvis generally supply?
lower limb
How does venous drainage of the pelvis generally work?
follow the arteries and are named similarly
