Q

Primate uterus chambers

A

-single chambered

17
Q

Parts of uterus

A

-Fundus
-Ovary
-uterine tubes
-body
-cervix
-Vagina

18
Q

Bicornuate uterus species

A

-results in uterine horns
-horns can be straight or curled
-ewe, mares, dogs, pigs

19
Q

Uterine body size

A

-body is typically short except in mares
-Mare has largest uterine body

20
Q

Uterus layers

A

-Serosa
>perimetrium; continuous with broad ligaments
-Muscularis
>myometrium (outer longitudinal, inner circular)
»outer layer of muscle layer is continuous with the broad ligament
-Mucosa
>endometrium

21
Q

SA increase in uterus (mares, ruminants)

A

-Mares: folds
-Ruminants: caruncles

22
Q

Function of uterus

A

-sperm transport
-site of embryonic attachment
-embryonic/fetal nutrition
-contractions during parturition
-regulation of the corpus luteum (PSF2 alpha will destroy with no fertilization)

23
Q

Llamas

A

-pregnancies always occur in the left horn
-but right horn is still used in development/growth
**if left is removed, pregnancy does still occur in the right

24
Q

Broad ligament attachment names

A

-Mesovarium-attaches to ovaries
-Mesosalpinx-attaches to uterine tube
-Mesometrium- attaches to uterus

25
Q

Broad ligament components in dogs and cats

A

-Suspensory ligament- connects kidney and ovary
>other species do not have suspensory ligament
-Proper ligament- connects uterus to ovary
-Round ligament of Uterus-part of broad ligament that goes through the inguinal canal

26
Q

Mare reproductive tract

A

-uterus develops longitudinal endometrial folds close to estrus
-broad ligament attachment on uterus on the dorsal aspect

27
Q

Bovine uterus

A

-ovaries and uterus have migrated to pelvic inlet
-Caruncles present in rows. Will form placentomes

28
Q

Cervix layers

A

-inner mucosa
-middle elastic fibro-muscular
-outer serosa (visceral peritoneum)

29
Q

Cervix functions

A

-seal against ascending contaminants and for retention of growing fetus
-sperm transport
-lubrication and flushing system (mucus production)

30
Q

Bovine and ovine Cervix

A

-annular transverse folds
>circular rings

31
Q

Sow cervix

A

-very long and complex folds
-hard to pass through for artificial insemination
-no vaginal fornix

32
Q

Mare cervix

A

-longitudinal folds
-easy to conduct artificial insemination

33
Q

Urethral tubercle

A

-opening of the urethra in dogs
>sitting on papilla

34
Q

Vestibulo-vaginal angle

A

-varies in different species
-Cow:straight; has suburethral diverticulum
-Mare: Oblique
-Dogs: Very oblique

35
Q

Suburethral diverticulum

A

-opening/pocket
-present in cows, sows, camelids

36
Q

Vulvar lips

A

-terminal portion of vestibule
-in animals, only have Labia minora, not labia majora
>dorsal and ventral commissures

37
Q

Clitoris

A

-ventral commissure
-homologue to penis (2 crura, body, glans)
>Os clitoridis in cats and dogs
>Sigmoid flexure in ruminants
-has clitoral prepuce and retractor muscles
