hypogastric a. (from internal iliac)
ovarian aa. Origin
aorta
uterine inn.
superior/inferior hypogastric plexus, common iliac nn.
where are tubes occluded for permanent sterilization?
isthmus
most common location for ectopic?
ampulla
fallopian tube sections from lateral to medial:
infundibulum, ampulla, isthmus, intramural
tubal blood supply

ovarian inn.
aortic plexus
ovaries covered by:
tunica albuginea (fibrous capsule) which is covered by germinal epithelium
tx for round ligament pain
acetaminophen and rest
broad lig
from lateral wall to uterus and adnexa; contains tubes, round lig, uterine/ovarian BVs, lymph, ureterovaginal nn., ureter
infundibulopelvic (IP)/suspensory lig of ovary
from pelvic wall to ovaries; contains ovarian BVs
round lig
remains of gubernaculum; from uterine corpus down and laterally through inguinal canal to labia majora
cardinal lig
from cervix/lateral vagina to pelvic wall; most important support structure; contains uterine BVs
uterosacral lig
from posterolateral supravaginal cervix into fascia over sacrum
first ligament cut during hyst
round lig
most common ureteral injury site during hyst
cardinal lig
pelvic organ prolapse from defect in:
pelvic diaphragm
perineal body cut with:
episiotomy
pelvic diaphragm
levator ani complex (iliococcygeus, puborectalis, pubococcygeus) and coccygeus
urogenital diaphragm
deep transverse perineal mm., urethral constrictor, internal/external fascia; maintains urinary continence
perineal body
central tendon of perineum for most support; median raphe of levator ani; convergence of: bulbocavernosus, superficial transverse perineal, external anal sphinctor
pelvic muscle blood supply
internal pudendal, inferior rectal, posterior labial aa.
