Uterus
Hollow, pear-shaped organ
Infundibulum: funnel-shaped lateral tube that projects beyond the broad ligament to overlie the ovaries
Ampulla: sidest part of the tube where fertilization occurs
Divided into fundus, body, and cervix
Usually anteflexed and anteverted
Covered with peritoneum except anteriorly below the os where peritoneum is reflected onto bladder
Menarcheal: 8 cm long by 4 cm wide
Postmenopausal: 3.5 to 5.5 cm long by 1 to 2 cm wide
Normal size : 2~3(thick)×4~5(width)×7~8 cm(length)

Ultrasonography of normal uterus
Uterine serosa layer: Linear highecho ;clear, smooth;
Myometrium: Homogeneous middleecho ;
Endometria: The middle line of high echo , around the weak echo . It is well known that the endometrium changes dynamically in response to cyclic hormonal flux.
rounded fundus is shown toward the left of the
image with the endometrial stripe rumming through
the middle of编t辑h版epput terine cavity.

Fallopian Tube（输卵管）
sometimes called suspensory ligament of the ovary Lies in ovarian fossa Fossa is bounded by external iliac vessels, ureter, and
obturator nerve Receives blood from ovarian artery Blood drained by ovarian vein into inferior vena cava
Right or left: normal variant in absence of pelvic masses
Retroverted: entire organ displaced posteriorly Retroflexed: body displaced with respect to cervix
