Female reproductive system Flashcards
Ovaries
located near the caudal pole of the kidneys; right lies cranial to left and is dorsal to the duodenum
Ovarian bursa
thin-walled peritoneal sac formed by the mesovarium and mesosalpinx; open to the peritoneal cavity by means of a slit-like orifice on the medial surface
Uterine tube (oviduct)
courses cranially and then caudally through the lateral wall of the bursa on its way to the uterine horn; appears as a cord-like thickening within the wall of the bursa
Infundibulum
dilated ovarian end of the uterine tube, has fimbriated margin and functions to engulf the oocyte after ovulation
Fimbriae
function to close the opening into the peritoneal cavity at the time of ovulation and prevent transperitoneal migration of oocytes
Abdominal ostium
entrance of the infundibulum into the uterine tube; region that fertilization takes place
Tubouterine junction
entrance of the uterine tube into the wider uterine horn; site where sperm and ova are regulated in their transit
Body of the uterus
where two uterine horns are joined together, cranial to the cervix, attached to the pelvis by the mesometrium
Uterine horns
wider portion of the uterus, bilateral
Broad ligaments
peritoneal folds on each side that attach to the lateral sublumbar region, suspend all the internal genitalia except the caudal part of the vagina, which is not covered by the peritoneum
Mesometrium
arises from the lateral wall of the pelvis and the lateral part of the sublumbar region and attaches to the lateral part of the cranial end of the vagina, uterine cervix, and uterine body, and the corresponding uterine horn
Mesovarium
continuation of the mesometrium, cranial part of the broad ligament, begins at the transverse plane through the cranial end of the uterine horn and attaches the ovary and the ligaments associated with the ovary to the lateral part of the sublumbar region
Mesosalpinx
peritoneum that attaches the uterine tube to the mesovarium and forms with the mesovarium the wall of the ovarian burse
Suspensory ligament of the ovary
joins the transversalis fascia medial to the dorsal end of the last rib; functions to hold the ovary in a relatively fixed position
Proper ligament of the ovary
short, attaches the ovary to the cranial end of the uterine horn
