Anatomy of Lateral Pelvic Wall Flashcards
Hole in the obturator membrane
onturator canal
1 of the origin points of levator ani, lying over the obturator internus
Tendinous Arch of the Levator ani
lateral rotator of hip
and Land mark of sciatic nerve (comes out inferior to the muscle)
- Piriformis muscle
Vessels of the pelvis arises from which artery
Internal iliac artery
Trauma to the pelvis bone results damage to which vessel
external iliac artery
what exception for a branch in the pelvis that arises from abdominal aorta
- superior rectal artery
- gonadal artery
What branches arise from the posterior division of the Internal iliac artery
gluteal arteries
remanant of the umbilical artery
Medial umbilical ligament—-
SUpply to bladder
Superior and inferior vesical arteries—-may or may not have INFERIOR vesical art. in females
Main artery. of the anterior iliac art. division?
- Internal pudendal artery….supplies most of the perineum
Arteries of the male perineum
> perineal artery>posterior scrotal art.> dorsal artery of the penis> deep artery
Erection of the penis mainly by which artery?
deep artery of the penis
Ligation of which pelvic artery is done in a hysterectomy
Uterine artery
Female version of inferior vesical artery
-Vaginal artery
What does the ovarian artery give off?
- tubal br.
- ovarian branch
What anastomoses are seen in the female pelvis?
- btwn uterine artery and ovarian artery
- btwn uterine artery and vaginal artery
What is meant by water under the bridge in the pelvis?
- ureter passes right underneath the uterine artery
- —therefore careful when ligating the uterine artery —-MAY DAMAGE the ureter
What is meant by water under the bridge in the pelvis?
- ureter passes right underneath the uterine artery
- —therefore careful when ligating the uterine artery —-MAY DAMAGE the ureter
Branches of the Internal Pudendal artery
- dorsal artery of clitoris
- labial arteries
- perineal artery
- inf. rectal artery
How may infection and cancer of the pelvis spread to the spine ?
Venous drainage into the INTERNAL vertebral venous plexus
Damage to the nerves on the lateral wall results in what exactly
- supply to lower limb and perineum
Where does the lymphatics of the ovaries and scrotum drain to
-drain in to LUMBAR are not external iliac
What is meant by trans-peritoneal spread?
- disease can penetrate through the peritoneal layer and disseminate into the peritoneal cavity
- sloughing off of metastatic cells in to the peritoneum helps in the spread of the cancer
