SUHAILAAFFRIN
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.
MIDDLE PART OF THE PELVIC LIMBSARAHHANIM
SUHAILA
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
