Q

List the 4 parts of the Quadriceps Femoris

A

Rectus Femoris
Vastus Lateralis
Vastus Medialis
Vastus Intermedius

17
Q

Rectus Femoris

A

O: Ilium
I: Tibial tuberosity via the patellar ligament
A: Flex hip, extend stifle

18
Q

Vastus Lateralis, Vastus Medialis, Vastus Intermedius

A

O: Proximal aspect of femur
I: Tibial tuberosity via the patellar ligament
A: Extend stifle

19
Q

Iliopsas

A

O: Ventral aspect of the lumbar vertebrae; cranioventral ilium
I: Lesser trochanter of the femur
A: Flex hip

** Muscle that goes up into the abdomen - formed by iliacus and the psoas major

20
Q

Cranial Tibial

A

O: Proximal and lateral aspect of the tibia near the extensor groove
I: Proximal plantar surface of metatarsals I and II
A: Flex tarsus; rotate paw laterally

  • tendon of this muscle held down by crural extensor retinaculum (or proximal extensor retinaculum in horse)
21
Q

Long Digital Extensor

A

O: Extensor fossa of femur
I: Extensor processes of distal phalanges of digits 2, 3, 4, and 5
A: Extend digits; flex tarsus

** Tendon held down by crural and tarsal extensor retinacula

22
Q

Fibularis Longus

A

O: Lateral collateral ligament; proximal aspect of the tibia and fibula
I: Tarsal bone IV; plantar aspect of proximal ends of metatarsals
A: Flex tarsus; rotate paw medially (pronation)

**AKA peroneus longus

23
Q

Gastrocnemius

A

O: Medial and lateral supracondylar tuberosities of the femur
I: Tuber calcanei (Switches with SDF at this position)
A: Extend tarsus; flex stifle

** Has 2 heads - lateral and medial - each contain a sesamoid bone (Fabellae sesamoid bones)

24
Q

Superficial Digital Flexor

A

O: Lateral supracondylar tuberosity of the femur (in common with lateral head of the gastrocnemius)
I: Tuber calcanei; plantar aspect of the base of the middle phalanx of digits 2, 3, 4, and 5
A: Flex stifle; extend tarsus (hock); flex digits

**Tendon of SDF is deep to the gastrocnemius and then switches to become superficial; tendon of SDF is superficial to the DDF tendon and then switches to deep at the flexor manica; intertendinous calcaneon bursa and subcutaneous calcanean bursa

25
Q

What are the 2 heads of the Deep Digital Flexor

A

Lateral Digital Flexor

Medial Digital Flexor

26
Q

Deep Digital Flexor

A

O: Proximal tibia and fibula and the adjacent interosseous membrane between the two
I: Plantar aspect of the base of distal phalanx of digits 1-5
A: Flex digits; extend tarsus

27
Q

Popliteus

A

O: Lateral condyle of the femur
I: Proximal and caudomedial aspect of the tibia
A: Flex stifle; rotate leg (crus) medially

**Popliteal sesamoid bone - lymph node also in this area

28
Q

Semitendinosus

A

O: Ischiatic Tuberosity
I: Medial Surface of Tibial Body, Tuber Calcanei via Common Calcanean Tendon.
A: Extend hip and hock; flex stifle
