Isthmus: hardest part; lies just lateral to the uterus
Length: 12 cm; supplied by ovarion arteries and veins
.

Ovary（卵 巢）
Almond shaped Attached to back of the broad ligament by mesovarium;
on right; on left by ovarian vein into lert renal vein
.
14
Sonography of the normal ovary
An ovoid homogeneous echodensity; follicular cysts are often present.
Infundibulum: funnel-shaped lateral tube that projects beyond the broad ligament to overlie the ovaries
Ampulla: sidest part of the tube where fertilization occurs
Uterus before and after the
Trail
Uterine wide diameter

Uterine Position
Midline anteversion: most common; degree of anteversion is bladder distention dependent
Right or left: normal variant in absence of pelvic masses
Retroverted: entire organ displaced posteriorly Retroflexed: body displaced with respect to cervix

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.
Supported by levator ani muscles and pelvic fascia
Round ligament keeps uterus in position

Uterine size
Prepubertal : 3 cm long by 0.5 to 1.0 cm wide
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)

Uterine longitudinal diameter
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
rounded fundus is shown toward the left of the
image with the endometrial stripe rumming through
the middle of th.e uterine cavity.
12
Fallopian Tube（输卵管）
Divided into fundus, body, and cervix
Usually anteflexed and anteverted
Covered with peritoneum except anteriorly below the os where peritoneum is reflected onto bladder
and ileum Anterior: bladder, ureters, ovaries,
fallopian tubes, uterus, and vagina
