cervix of uterus
neck; extends into vagina; cervical canal is about 2 cm long, between internal os & external os
normal uterine position is
anteverted and anteflexed
anteverted uterus
entire uterus is bent forward onto bladder; longitudinal axis of vagina makes 90-100degree angle with uterine cervix
anteflexed uterus
angle of uterine body is bent forward about 15-20 degrees compared to uterine cervix
when urinary bladder fills, uterus is
pushed up & back; it becomes retroflexed first & then retroverted
variations on normal position of uterus
can be retroflexed and/or retroverted
rectouterine pouch aka
pouch of Douglas
rectouterine pouch is place where
peritoneum reflects from rectum onto uterus
uterovesical pouch is place where
peritoneum reflects from uterus onto urinary bladder
broad ligament of uterus
comprised of peritoneum; attached to lateral sides of uterus
portions of broad ligament of uterus
mesometrium, mesovarium, mesosalpinx
mesometrium of broad lig.
attached to uterus
mesovarium of broad lig.
attached to ovary
mesosalpinx of broad lig.
attached to fallopian tube
gubernaculum has two remnants
ovarian ligament & round ligament
ovarian ligament extends
from ovary to uterus
round ligament extends
from uterus, courses through inguinal rings & canal to end in labium majus
uterosacral ligament
peritoneum & subserous fascia; attaches sacrum to cervix; helps "anchor" cervix, keeping it in midline
pubocervical ligament
portion of pubovesical ligament
lateral (transverse) cervical ligament aka
cardinal ligament
lateral cervical ligament
composed of peritoneum & subserous fascia; located at inferior end of broad ligament
lateral cervical ligament conveys
uterine vessels; of the ligaments, greatest support; attached to cervix
uterine support (greatest to least)
pubococcygeus, urogenital diaphragm, urinary bladder, areolar tissue & endopelvic fascia, ligaments of uterus
ligaments of uterus that provide uterine support (greatest to least)
lateral cervical, uterosacral, broad, ovarian & round, pubocervical
ovarian & round ligaments
two remnants of gubernaculum
uterine a. is branch of
internal iliac
uterine a. courses in
cardinal ligament
uterine a. crosses over
ureter
uterine a. crosses
superior to ureter
uterine a. divides into
descending branches & larger ascending branch
descending branches of uterine a.
vaginal & cervical branches
uterine a. also supplies
many branches to uterus; usually also supplies tube, may supply ovary
lymphatic drainage of uterus important because of
high frequency of uterine cancer
lymphatics from fundus of uterus
drain to para-aortic group of lumbar nodes
body of uterus, lymphatics
drain to external iliac nodes via broad ligament; to internal iliac nodes via uterine vessels; to superficial inguinal nodes via path of round ligament
cervix of uterus, lymphatics
drains to sacral, external, internal & common iliac aa.
innervation of uterus via
uterovaginal plexus portion of pelvic plexus
parasympathetics travel to uterus via
pelvic splanchnic nn
sympathetics travel to uterus via
