UPPER PART OF PELVIC LIMBSYUHADAH

TENGKU HAJARNABILA

GLUTEUS MEDIUS Origin: Upper surface

of the ilium of the pelvis Insertion: Top and

back of the upper end of the femur

Action: Extends the hip joint (important muscle for rearing, jumping, kicking and propulsion) ; abduction

GLUTEUS SUPERFICIAL Origin: Gluteal

fascia and sacrum Insertion: On the

greater trochanter of the femur

Action: Extensor and flexor of the hip joint

SARTORIUS Origin: Tendon of the

psoas minor and the fascia of the iliac

Insertion: Medial patellar ligament and the tuberosity of the tibia

Action: Flexes the hip joint and adducts the limb

RECTUS FEMORIS Origin: Two small

adjacent areas on the body of the pelvis just in front of the hip socket.

Insertion: The base and anterior surface of the patella

Action: Flexes hip joint and extends stifle joint

VASTUS LATERALIS Origin: Lateral surface

of the femur, from the trochanter major to the supracondyloid fossa.

Insertion: Anterior surface of the patella and the tendon of the rectus femoris.

Action: Extends stifle joint.

TENSOR FASCIA LATAE Origin: Point of the hip

(outer front corner of the illium of the pelvis)

Insertion: Into the fascia of the leg, it surrounds the vastus lateralis and the rectus femoris

Action: Flexes hip joint; extends stifle joint.

SEMIMEMBRANOSUS Origin: The ventral

surface of the ischial tuberosity.

Insertion: Medial surfaces of distal femur behind the collateral ligament

Action: Extends the hip and adducts the limb

SEMITENDINOSUS Origin: Ischial tuberosity Insertion: Medial surface

of tibia, tuber calcanei. Action: Extends hip, stifle

and hock joint; flexes stifle joint when hindfoot is lifted from the ground.

GRACILIS Origin: Symphysial tendon,

prepubic tendon, accessory ligament, and the ventral surface of the pubis.

Insertion: Tibial crest by strong tendinous bands to the tuber calcanei.

Action: Extends the hip and tarsal joints, flexes the stifle joint, and adducts the limb.

TIBIALIS CRANIALIS Origin : Upper end of the

outer side of the tibia Insertion : Front of the upper

end of the large metatarsal bone and inside back corner of the ankle

Action : Flexes the ankle joint

PERONEUS TERTIUS Origin : From a depression on

the outer surface of the very bottom of the femur

Insertion : Inner front corner f the upper end of the large metatarsal

Action : Flexes the ankle joint

EXTENSOR DIGITORUM LONGUS Origin : Outer of the very

bottom of the femur Insertion : Upper edge of

the front surface of the last toe bone of both toes

Action : Extend all three toe joint

PERONEUS LONGUS Origin : Upper end of the

tibia Insertion : Upper end of

the inner rear corner of the large metatarsal bone

Action : Flexes the ankle joint and rotates the foot inwardly

EXTENSOR DIGITORUM LATERALIS Origin : Between femur and

tibia Insertion : Upper front end of

the middle toe bone of the outer toe

Action : Extend the upper two toe joints of the outer toe

SOLEUS Origin : Outer surface of the

upper end of fibula Insertion : Into the tendon of

the gastrocnemius and into the top of the heel bone

Action : Assists the gastrocnemius in extending the ankle joint

GASTROCNEMIUSOrigin: Outer head - vertical line on the outer

rear edge of the femur , three fourths of the way down the bone.

Inner head - Area on the inner rear corner of the femur, at a level lower than the origin of the outer head.

Insertion: Top of the heel bone (calcaneous).

Action: Flexes the knee joint; powerfully extends the ankle joint, propelling the animal forward.

FLEXOR DIGITORUM SUPERFICIALIS

Origin : Outer rear corner of the femur

Insertion : Rear surface of the middle to bone of both toes

Action : Extend the ankle joint, flexes the toes and knee joint

FLEXOR DIGITORUM PROFUNDUS Origin : 1. Flexor Digital Longus :

Middle third of the rear surface of the tibia

2. Tibialis Caudalis : Extreme outer rear corner at the upper end of the tibia

Insertion : Lower end of the last toe bone of both toes

Action : Flexes all the toe joints and extend the ankle joint
