1

Internal Obturator
Origin
Insertion
Action
Innervation

Origin: symphysis pelvis (ischium and pubis- dorsal)

Insertion: the trochanter fossa of the femur

Action: rotate the pelvic limb laterally at the hip joint

Innervation: sciatic nerve

2

External Obturator
Origin
Insertion
Action
Innervation

Origin: the ventral surface of the pubis and ischium

Insertion: trochanteric fossa

Action: rotate the pelvic limb laterally at the hip joint

Innervation: Obturator nerve

3

Quadraceps Femoris
4 parts
action of rectus femoris?
origin and insertion of all heads?
innervation?

1. rectus femoris
- action: to extend the stifle joint and flex the hip joint
- origin: ilium
2. vastus lateralis
3. vastus intermedius
4. vastas medialis

Origin: (vasti muscles) - proximal femur
Insertion: tibial tuberosity
Innervation: femoral nerve

4

Gemelli m.
Action
Innervation

Action: rotate the pelvic limb laterally at the hip joint

Innervation: Sciatic Nerve

5

Quadratus Femoris
Action
Innervation

Action: extend the hip joint and rotate pelvic limb laterally

Innervation: Sciatic Nerve

6

Patella and patellar ligament

Patella -sesamoid bone, articulates with the trochlea of the femur

patellar ligament - tendon of insertion of quadreceps femoris and that extends from the patella to the tibial tuberosity

7

Iliopsas
Action
Innervation

Action: to flex the hip joint
Innervation: lumbar spinal nerves and femoral nerve
