Female Reproductive Anatomy Flashcards
Where does the mare uterus lie during pregnancy
Uterus lies on the ventral body wall
Where does the cow uterus lie during pregnancy
Displaced to the right, by the rumen
Where does the ovary of the bitch lie in the body cavity
Ovary is caudal to the caudal pole of the associated kidney. Close to the last rib
Broad ligament
Bilateral sheets that anchor organs to abdominal roof and pelvic walls
2 layered tissue that sandwiches the reproductive tract
Peritoneum
Peritoneum fold of the uterus
Mesometrium
Peritoneum fold of the oviduct
Mesosalphinx
Peritoneum fold of the ovary
Mesovarium
Lateral fold of the Peritoneum
Round ligament uterus
Fold of the peritoneum that covers or hides the ovary
Ovarian bursa which is an enclosed pouch
Size of bitch ovarian bursa
DEEP
Size of the mare ovarian burrsa
Shallow
Suspensory Ligament
Peritoneal fold that attaches cranial pole ovary to the abdominal wall adjacent to the last rib
Ligament of the uterine horns
Inter-cornual ligament
Proper ligament
Caudal pole of ovary to the adjacent horn
3 Veins of the female reproductive tract
Ovarian, uterine, and vaginal vein
4 Arteries of the female reproductive tract
Uterine branch of the ovarian artery, Ovarian artery from the aorta, Uterine artery from int. illiac, Vaginal artery
Benefit of the blood supply to the ovary
The artery is in close contact with the vein, allowing the transfer of PG/PGF2a
What is the cause of acute death following parturition in the mare?
Rupture of the uterine artery
Lymphatic drainage
Lymph drains into the aortic and sacral-iliac lymph nodes
What type of innervation is in the female reproductive tract
Motor and autonomic. (Parasympathetic and sympathetic)
Innervation to the ovary
Parasympathetic from Vegas and Sympathetic from inter/caudal mesenteric plexus
What supplies the vulva
Motor nerves
Result of a disruption of the nerve supply in the female reproductive tract?
Little apparent effect on reproduction
Ovary Function
Produce the female gamete. Hormone production
How does the ovary produce the female gamete: oocyte
Oogenesis and folliculogenesis
Folliculogenesis
Development of the follicle/hormonal support
OOgenesis
Development of the oocyte
Location of mare ovulation
Ovulation Fossa. Reversed Cortex and Medulla
Empty follicle after ovulation
Corpus albicans
Functions of the oviduct
Gamete transport, site of fertilization, secretion of molecules that support fertilization and early embryo development
Rabbit and mouse uterus classification
Duplex
Pig and bitch uterus classification
Bicornate with long uterine horns
Cow, ewe, doe uterus classification
Bicornate with smaller uterine horns
Mare uterus classification
Bicornate with larger uterine body, small uterine horns
Function of cervix
Transport, block, reservoir for sperm. Blocking bacteria. Birth canal
Cervical Plug
Thick mucus secretion to protect uterus from infection during pregnancy
Cow and ewe cervical structure
Annular rings
Mare cervical structure
Longitudinal folds
Sow cervical structure
Cork-screw like, interdigitating prominences. No fornix
What part of the oviduct is the site of fertilization
Ampullary-isthmus junction
Parts of the Oviduct
Infundibulum, Ampulla, and Isthmus
