Flashcards in Lab 10: Hindlimb Deck (22):
0

2 distal branches of medial saphenous vein

cranial and caudal branches of the medial saphenous vein

1

borders of the femoral triangle

caudal: pectineus m.
lateral: quadriceps femoris
medial: external abdominal oblique

2

2 muscles that make up the iliopsoas m.

psoas major and iliacus m.

3

what lymph nodes are in the femoral triangle?

deep inguinal lymph nodes

4

origin of adductor m.

pelvic symphysis

5

fx of accessory ligament

limits pronation of the limb and helps prevent hip luxation (dislocation). It is unique to the horse.

6

Where does accessory ligament originate and insert?

Origin: prepubic tendon
Insertion: head of femur.

It enters the acetabulum at the acetabular notch and travels under the transverse acetabular ligament

7

What is the major flexor of the hip?**

iliopsoas m.

8

Where does iliopsoas m. insert?

lesser trochanter of the femur

9

Insertion of cranial head of biceps femoris

patella

10

Insertion of middle head of biceps femoris

lateral patellar region and tibial tuberosity

11

Insertion of the caudal head of the biceps femoris

tuber calcaneus via the thick crural fascia

12

What 2 muscles does the common peroneal n. run between caudal to the stifle?

biceps femoris and lateral head of the gastrocnemius m.

13

2 major branches of the sciatic nerve

common peroneal n. (aka common fibular n.) and tibial n.

14

What 2 muscles does the tibial n. dive between?

lateral and medial head of the gastrocnemius m.

15

Why is femoral n. important?

Allows horse to stand. It is motor only.

16

Is saphenous n. motor, sensory, or both?

sensory only

17

Is sciatic n. motor, sensory, or both?

both

18

What are the splint bones?

metatarsals II and IV. Often called "buttons" for their feel on palpation

19

Cannon bone = ? What is it's main function?

metatarsal III. Carries the weight of the limb

20

where are proximal sesamoid bones located?

on plantar surface of fetlock

21

where is distal sesamoid bone located?

on plantar surface of coffin joint
