Female repro Flashcards
Which of the following is true regarding ovaries and ligaments?
A The cortex of the ovary contains the blood and lymphatic vessels while the central medulla contains nerves, smooth muscle fibers and connective tissue
B The capsule of the ovary is formed by the peritoneum
C The infundibulum is lined by fimbriae that swell to block the ovarian bursa during ovulation
D Cats ovarian bursa typically contains fat while the dogs does not
C true (keeps ova from entering abdominal cavity) A (false, they all remain within the central medulla) cortex = follicles B (false, connective tissue - tunica albuginea) which is then covered by peritoneum D dogs are fat, not cats
Which of the following is true regarding the ovaries?
A The ovarian arteries arise from the aorta cranial to the renal arteries and deep circumflex iliac arteries
B The left ovarian vein empties into the renal vein while the right empties into the vena cava
C The lymphatics of the ovaries drain into the iliac lymph nodes
D The ovarian vessels are supplied by the parasympathetic nervous system
A (false, caudal to renal, cranial to deep)
B TRUE
C (false, lumbar)
D false, sympathetics!
(ovarian follicles and interstitial tissue are devoid of sympathetic innervation)
Which of the following is true regarding the uterus?
A The uterus is composed of four layers/tunics: serosa, muscularis (myometrium), submucosa, and mucosa (endometrium)
B The endometrium is the thickest of the uterine layers
C The myometrium is made of a thick, inner, longitudinal layer and outer, thin, circular smooth muscle layer
D Innervation of the uterus is through the hypogastric and pelvic nerves, transecting these will alter the frequency and amplitude of uterine contractions in dogs
A NO submucosa
B TRUE
C outer, thin, longitudinal; inner, thick, circular
D will NOT alter uterine contractions( the innervation is accurate)
Where do the suspensory, proper, and round ligaments go?
S: last rib to ovary
P: attaches ovary to cranial end each uterine horn
R: uterus broad ligament through inguinal canal into SQ region of the vulva
When and where does fertilization in the bitch occur?
7 days post ovulation in uterine tube = oviduct
What are the 3 stages of parturition?
1: internal contractions
2: expulsion of fetus
3: expulsion of placenta
True/False: Dogs have progesterone sourced from ovaries and placenta
FALSE: ovary only –> progesterone in dogs
placental secretion of progesterone occurs day day 40 in cats (as well as ovary)
How long can parturition last in dogs? cats?
Dogs = a few - 36hr (no more than 4 hrs between pups, no more 30 min active straining) Cats = 6-48hr can be interrupted
Which of the following statements is true?
A The external pudendal artery supplies the vagina
B The urogenital system is separate from the hindgut from the start of fetal development
C Fusion of the paired mesonephric ducts results in the formation of the vestibule
D The cingulum forms from fusion of the urogenital sinus with the fused paired Müllerian ducts
D TRUE cingulum = vestibulovaginal junction
A external –> vulva; internal –> vaginal –> vagina
B External genital initially contiguous with hindgut
C paired mesonephric –> (cranial vagina)
Which of the following statements is true?
A Estrus is accompanied by a decrease in serum progesterone and cornification of epithelial cells
B Smooth muscle is confluent with the distal 3rd of the vaginal from the urethra
C A mixed bacterial population can normally be cultured in 95% normal bitches
D Neutrophils are normally found on cytology of the vaginal exudate in proestrus
C true
A INCREASE in serum progesterone
B striated m
D only in DIESTRUS
True/false: Serosanguinous or mucoid discharge is a normal finding during proestrus.
True
most common tumor of the canine uterus?**
feline uterus
leiomyomas = 90% in dogs
adenocarcinoma in cats
what is the embryologic source of the Cranial vagina
Fusion of paired paramesonepheric (Müllerian ducts) → Cranial vagina
