Q

borders of the femoral triangle

A

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

1
Q

2 distal branches of medial saphenous vein

A

cranial and caudal branches of the medial saphenous vein

2
Q

2 muscles that make up the iliopsoas m.

A

psoas major and iliacus m.

3
Q

what lymph nodes are in the femoral triangle?

A

deep inguinal lymph nodes

4
Q

origin of adductor m.

A

pelvic symphysis

5
Q

fx of accessory ligament

A

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

6
Q

Where does accessory ligament originate and insert?

A

Origin: prepubic tendon
Insertion: head of femur.

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

7
Q

What is the major flexor of the hip?**

A

iliopsoas m.

8
Q

Where does iliopsoas m. insert?

A

lesser trochanter of the femur

9
Q

Insertion of cranial head of biceps femoris

A

patella

10
Q

Insertion of middle head of biceps femoris

A

lateral patellar region and tibial tuberosity

11
Q

Insertion of the caudal head of the biceps femoris

A

tuber calcaneus via the thick crural fascia

12
Q

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

A

biceps femoris and lateral head of the gastrocnemius m.

13
Q

2 major branches of the sciatic nerve

A

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

14
Q

What 2 muscles does the tibial n. dive between?

A

lateral and medial head of the gastrocnemius m.

15
Q

Why is femoral n. important?

A

Allows horse to stand. It is motor only.

16
Q

Is saphenous n. motor, sensory, or both?

A

sensory only

17
Q

Is sciatic n. motor, sensory, or both?

A

both

18
Q

What are the splint bones?

A

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

19
Q

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

A

metatarsal III. Carries the weight of the limb

20
Q

where are proximal sesamoid bones located?

A

on plantar surface of fetlock

21
Q

where is distal sesamoid bone located?

A

on plantar surface of coffin joint
