Female pelvic cavity Flashcards
landmark for ureter
crosses over external iliac artery at the bifurcation
What is the sacroiliac joint at L5-S1 a landmark for
- common iliac artery bifurcation
- ureter
- lumbosasral trunk
portions of the rectum
- rectum
- ampulla of rectum (change in direction of rectum)
- anal canal
structure that attaches the ovary to the uterus
ovarian ligament
contained within suspensory ligament of ovary
ovarian artery and veins
structures in female gubernaculum
- round ligament of uterus
- ligament of ovary
pathway of round ligament
deep to inguinal ring –> inguinal canal –> labia majora
branches of internal iliac artery (10)
- iliolumbar artery
- lateral sacral artery
- superior gluteal artery
- inferior gluteal artery
- internal pudendal artery
- middle rectal artery
- umbilical artery
- obturator artery
- uterine artery
- vaginal artery
location of iliolumbar and lateral sacral artery
arise soon after bifurcation
iliolumbar –> ascends lateral to lumbar vertebrae on sacral iliac joint
lateral sacral –> descends laterally on sacrum
path of superior gluteal artery
- exits between the lumbosacral trunk and anterior rami of S1
- exits pelvic cavity via greater sciatic foramen and superior border of piriformis
Path of inferior gluteal artery
- exits between anterior rami of S1 and S2
- exits pelvic cavity via the greater sciatic foramen and inferior border of piriformis
path of internal pudendal artery
- exits after anterior rami of S2
- exits pelvic cavity via greater sciatic foramen and inferior border of piriformis (but anterior and medial to inf. glut. art.)
path of middle rectal
- highly variable
- branches off internal iliac or internal pudendal
path of umbilical artery and branches
- travels in lateral aspect of the pelvic cavity
- provide oxygen and nutrient rich blood to placenta
- give rise to superior vesicle arteries
path of obturator artery
- travels in lateral aspect of the pelvic cavity
- heads to obturator foramen to supply medial aspect of thigh
path of uterine artery
- travels on lateral wall where uterus meets cervix
path of vaginal artery
- arises from either uterine or internal iliac artery
- between uterus and rectum
branches of uterine artery
- ovarian and tubal branches
- vaginal branch attaching to vaginal artery
relationship between uterine artery and ureter
uterine artery crosses ureter superiorly
