1

boundaries of pelvic cavity

cr: pelvic inlet
cd: pelvic diaphragm muscles (levator ani and coccyges)
lateral border: body of ilium, origins of pelvic diaphragm muscles, sacrosciatic ligaments, and muscles that overlie the ligament
Dorsal: sacral and first few cd vertebrea
ventral: publis

2

pelvic inlet boundaries

Dorsally :promontory of the sacrum
Laterally: ilium
Ventrally: pubis

3

cd extent of peritoneal cavity

boundaries for peritoneal cavity same as for abdominal cavity except caudally

caudal boundaries: pararectal fossa, rectogenital pouch, vesicogenital pouch, pubovesical pouch

4

pubovesicle pouch

bladder -> pelvis, split by median ligament of the bladder

5

rectogenital pouch

space between rectum and reproductive organs (vagina or genital fold)

6

pararectal fosse

dorsal body wall/ pelvis? and rectum

7

vesicogenital pouch

lies between uterus and vagina (or genital fold) dorsally and the bladder ventrally and lateral ligaments of the bladder laterally

8

Gross structures of female reproductive tract

ovaries, uterine tubes, uterus, cervix, vagina, vestibule, vulva

9

ovaries

dorsally locales, anchored to dorsal body wall by mesovarium; horse has big ovarian bursa and ovulation fossa (ovulate 1 follicle at a time); ovary is heart shapped

10

uterine tubes

carry egg to uterus

11

broad ligament

mesovarium, mesosalpinx, mesometrium

12

remnants of the gubernaculum

proper ligament of the ovary and round ligament of the uterus

13

ovarian bursa borders

mesosalpinx and mesovarium

14

proper ligament of the ovary

found on free edge of mesovarium running from ovary to uterine horn

15

round ligament of the uterus

in free edge mesometrium

16

mesovarium

suspends ovary

17

mesometrium

suspends uterus (body and horns)

18

mesosalplinx

suspends uterine tubes

19

Blood supply female reproductive tract

aorta ->
1. Ovarian- supplies ovary, mesovarium
2. External iliac ->
2a.Uterine- supplies uterus, mesometrium
2b.Deep femoral ->pudendoepigastric trunk -> external pudendal (inguinal canal, blood supply to mammary gland)
3. Internal iliac -> internal pudendal -> vaginal -> uterine branch of vaginal (uterus blood supply, mesometrium)

20

collateral circulation of uterus

aorta -> external iliac -> uterine
aorta -> internal iliac -> internal pudendal -> vaginal -> uterine branch of vaginal

21

mammary gland of the mare

lactiferous ducts -> lactiferous sinus (gland sinus -> teat sinus)-> teat canals -> teat orifices

22

lactiferous sinus

made up of glands sinus (found within mammary gland itself) and teat sinus (found within teat)

23

teat canals other name

papillary ducts

24

teat orifces

two orifices per teat

25

blood supply mammary gland

provided by branches of external pudendal artery

26

clinical correlates female reproductive tract

reproductive cycles, artificial insemination, pregnancy, ovarian tumors

27

reproductive cycles

follow by u/s per rectum, look at ovary for follicles or corpus leuteum, look at uterine horn and body for edema (cut orange appearance)

28

artificial insemination

uterus and rectum relationship; deep horn insemination goes to horn follicle ovulating to; cervix has longitudinal folds so easier to inseminate

29

pregnancy

uterine artery can rupture but this tends not to be fatal because its contained in broad ligament; most common in mares that have had multiple foals

30

ovarian tumors

granulose cell tumor (fairly common); may need flank incision to get it; if small enough can go in laparoscopically; these tumors -> hormone production -> change in behavior
