1

palpable bony land marks hindlimb of horse

tuber coxae, tuber sacrale, ischiatic tuberosity

2

superficial drainage of the hindlimb

medial saphenous vein (cr and cd branches) and lateral saphenous vein to femoral vein

3

medial saphenous vein

emerges between sartorial and gracilis on medial surface of thigh; bifurcates in proximal part of leg after it runs over stifle into cr and cd branches

4

cd branch medial saphenous vein

passes cddistally and run sin depression between common calcanea tendon and eep digital flexor to the jock

5

cr branch medial saphenous vein

continues distally crossing medial surface of tibia and anastomoses with cranial tibial vein at hock, ends on dorsomedial surface of hock by giving rise to dorsal common digital vein

6

veins in hind limb

femoral, popliteal, cr tibial, medial and lateral plantar

7

bony landmarks of pelvis

tuber coxae, tuber sacrale, ischiatic tuberosity
- tuber coxae most cr, tuber sacrale most dorsal, ischiatic tiberoslty most cd and ventral

8

bony landmarks of femur

greater, lesser, and 3rd trochanters
- greater lateral, cr
- lesser medial
- 3rd lateral, ventral

9

what happens over tarsocrural joint

anastomosis of cr tibial with cr branch of medial saphenous vein

10

femoral nerve

-saphenous nerve is a branch of large and important femoral nerve
-femoral nerve (L4-L6)
- femoral nerve passes between rectus femoris and vests medals, the cr and medial heads respectively of the quadriceps femoris
- innervates extensor action of quadriceps on the stifle which is essential to support the limb

11

gracilis attachments and innervation

-proximal attachment along pelvis (iliopubic eminence/ pubis/ symphysis)
- distal attachment to cr tibia and medial patellar ligament
- innervation obturator

12

adductor attachments and innervation

- proximal attachment along pelvis (iliopubic eminence/ pubis/ symphysis)
- distal attachment distal femur
- innervation obturator nerve

13

pectineus

- proximal attachment along pelvis (iliopubic eminence/ pubis/ symphysis)
- distal attachment distal femur
- innervation obturator nerve

14

sartorius

- proximal attachment along pelvis (iliopubic eminence/ pubis/ symphysis)
- distal attachment iliac fascia to medial aspect of stifle
- innervation femoral nerve

15

adductors

gracilis, adductor, pectineus, sartorius (some adduction)

16

sartorius fx

some adduction, hip flexion, only one belly unlike dog who has cr and cd belly

17

quadriceps femoris 4 heads

vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris

18

quadriceps femoris attachments

- all vastus heads arise from proximal femur
- rectus femoris arises from ilium just cr to acetabulum
- all attach via patellar ligaments to tibial tuberosity
-innervation- via femoral nerve

19

iliopsoas

- ventral surface of vertebrea (psoas major) and ilium/ sacrum (iliacus) to lesser trochanter
innervation- ventral branches of lumbar nerves/ lumbosacral plexus likely femoral

20

Superficial gluteal

- tuber coxae/ gluteal fascia to 3rd trochanter
- cr gluteal and cd gluteal nerve

21

deep gluteal

- ischial spine to greater trochanter
- cr gluteal

22

middle gluteal

- gluteal surface of ilium to greater trochanter
- cr gluteal

23

accessory gluteal

- on deep surface of middle gluteal arises form similar region of gluteal surface of ilium as middle gluteal to greater; trochanteric bursa
- cr gluteal

24

femoral nerve innervates

- iliopsoas (partially)
- sartorius
-quadriceps femoris

25

femoral triangle

space between the sartorius crly, the pectineus cdly, the external abdominal oblique aponeurosis medially and quadriceps laterally

26

vascular lacuna

(dorsal) base of the narrow femoral triangle

27

femoral triangle contains

femoral vessels and the deep inguinal lymph nodes

28

deep inguinal lymph nodes

receive nearly all the lymph from hindlimb

29

main arterial pipeline of hindlimb

aorta -> ex iliac -> cr tibial -> dorsal metatarsal -> (perforating tarsal) -> medial/ lateral plantar and medial / lateral plantar metatarsal -> medial and lateral plantar digital

30

internal iliac artery

aorta -> internal iliac artery
1. internal pudendal
1a. artery of the bulb of the penis
1b. prostatic artery
1c. vaginal
1cc. uterine branch of vaginal
2. umbilical artery
2a. artery of the ductus deferens
3. cr gluteal
3a. obturator artery
3aa. middle artery of the penis
4. cd gluteal
