attachment of broad
ligament to lateral
pelvic wall in true pelvis
What is the ovary suspended by? (3)
- Broad ligament –
mesovarium - Suspensory ligament of
ovaries - Ligament of the ovary –
attach to uterus (runs
within mesovarium)
What are the uterine tubes?
- Fallopian tubes
Uterine tubes:
* Extends…
* Conduct
- Extends laterally within broad lig.: uterine horns & open into peritoneal cavity near ovaries
- Conduct oocyte from ovary to uterine cavity
- Divide into 4 parts:
Uterine tubes
Blood supply:

Ovary
* Blood supply:
- Ovarian arteries (AA)
Ovary
* Venous drainage:
- Pampiniform plexus merge
to form ovarian vein - IVC and renal vein

tubal junction
Posteroinferior
Uterus

- ______ to utero-
tubal junction
Anteroinferior
- Broad ligament of the
uterus - 2x layer peritoneum:
extend from sides of
uterus – lateral walls &
pelvic floor
- Broad ligament of the
uterus
Assist:
position of uterus

uterus - Laterally:
peritoneum of broad ligament lies over
vessels: suspensory
ligament of ovaries
Position of uterus
* Normal Position of Uterus:
- Anteflexed and anteverted
Position of uterus
- Positions of fundus
* Retroversion:
* Anteversion:
- Fundus points posterior against rectum
- Fundus tipped forward
- Position of body
- Retroflexed
- Uterus tipped backwards
- Position of body
- Anteflexed
- Body is bent sharply forward
- Position of body
- Retrocession
- ‘Recede’
Uterus relations
* Anterior:
- Anterior: vesicouterine
pouch, superior surface of
bladder
Uterus relations
* Lateral:
- Lateral: broad ligament of
uterus, transverse cervical
ligaments, ureters
(supravaginal part of cervix)
Uterus relations
* Posterior:
- Posterior: rectouterine
pouch, rectum
Uterus
Supporting structures
Ligaments =
- Lateral: broad ligament of
uterus, transverse cervical
ligaments, ureters
(supravaginal part of cervix)

Uterus
* _______ organs
Surrounding
Uterus
* Blood supply:

venous plexus continuous
with uterine venous plexus
(→ internal iliac veins)
Vagina & uterus

- Deep perineal nerve (B: pudendal)
Vagina & uterus
* Rest of vagina & uterus – visceral:
- Uterovaginal nerve plexus
Vagina & uterus
* Sympathetic innervation:
- Inferior thoracic → lumbar
splanchnic nerves
Vagina & uterus
* Parasympathetic innervation
