1

external iliac branches

deep circumflex iliac cr and cd branches;
deep femoral

2

deep circumflex iliac cr and cd branch bifurcation

lateral iliac lymph nodes located at bifurcation into cr and cd branches

3

deep circumflex iliac cd branches

seen with lateral cutaneous femoral nerve at flank of stifle with sub iliac LNs

4

external pudendal

branches into cr artery of the penis (males) and supplies mammary gland (via cd superficial epigastric) (female)

courses through inguinal canal in both sexes

5

internal iliac branches male

1. umbilical -> artery of ductus deferenes
2. Internal pudendal ->
2a. prostatic artery
2b. artery of bulb of the penis
3. cd gluteal
4. cr gluteal -> obturator -> middle artery of the penis

6

internal iliac branches female

internal pudendal -> vaginal artery -> uterina branch of vaginal artery

7

what vessels supply blood to penis and testis

penis:
aorta -> external iliac -> deep femoral -> pudendoepigastric trunk -> external pudendal -> cr artery of penis

aorta -> internal iliac -> cr gluteal -> obturator -> middle artery of the penis

aorta -> internal iliac -> internal pudendal -> artery of bulb of the penis

testis:
aorta -> testicular artery

8

what vessels supply blood to the ovaries and uterine tract

uterus:
aorta -> external iliac -> uterine artery

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

ovary:
aorta -> ovarian

9

superficial inguinal ring

split in aponeurosis of external abdominal obliques

10

deep inguinal rings

cd- inguinal ligament (from ex abdominal obliques)
cr- cd free edge of int. abdominal oblique
med- rectus abdominus

11

inguinal ligament

strengthened cd edge of aponeurosis of external oblique; sweeps from prepubic tendon dorsolateraly toward coxal tuber

12

vascular lacuna

cd to inguinal ligament; this = base of narrow femoral triangle

13

what passes through vascular lacuna

external iliac artery and vein; structures that disappear cd to inguinal ligament enter vascular lacuna; structures passing through vascular lacuna enter sq tissues of groin

14

vaginal ring

lies at the begging of the evagination of the parietal peritoneum through the inguinal canal; forms the communication between general peritoneal cavity and cavity of the vaginal tunic; this is only found in males

15

vaginal ring vs deep inguinal ring

deep inguinal ring in both males and females; structures passing through deep inguinal ring enter inguinal canal

16

what structures pass through inguinal canal in both female and male

external pudendal artery, genitofemoral nerve, lymphatic vessels

17

what structures pass through inguinal canal only in male

parietal peritoneum evaginated down through ring to form vaginal tunic, deferent duct with mesoductus and testicular vessels and nerves in mesorchium pass through as spermatic cord

18

mesenteric structures surrounding the testicle

vaginal tunic is outpocketing of peritoneum name is based on if it is directly surrounding a structure (visceral vaginal tunic) or that component just deep to skin and spermatic fascia (parietal vaginal tunic); vaginal cavity is space between the visceral and parietal vaginal tunic; the ductus deferens which is enclosed in the spermatic cord which is covered by vaginal tunic is suspended by mesoductus deferens; testicular vessels and nerves are also part of spermatic cord which is covered by vaginal tunic; the testicular vessels and nerves are enclosed by mesorchium which is fold of serous membrane that attaches cuadually to parietal vaginal tunic and ends distally by forming ligament of the tail of the epididymus

19

mesoductus deferens

the ductus deferens which is enclosed in the spermatic cord which is covered by vaginal tunic is suspended by mesoductus deferens

20

mesorchium

the testicular vessels and nerves are enclosed by mesorchium which is fold of serous membrane that attaches cuadually to parietal vaginal tunic and ends distally by forming ligament of the tail of the epididymus

21

what muscle does cremaster originate from?

internal abdominal oblique

22

primary blood supply for mammary glands

aorta -> external iliac -> deep femoral -> pudendoepigastric trunk -> external pudendal (supplies mammary gland via cd superficial epigastric)

23

what lymph nodes drain mammary glands

superficial inguinal

24

flow of milk from lactiferous ducts to teat orifice

lactiferous duct
lactiferous sinus (gland sinus -> teat sinus)
Teat canal (aka papillary ducts)
Teat orifice

25

skin folds that make up prepuce of horse

external lamina
- preputial orifice
internal lamina
- preputial fold
- preputial ring
- preputial cavity
fossa glandis
uretheral sinus
