Definition

Adductor

Origin: Pelvic symphysis, ischiatic arch and ventral surface of pubis and ischium Insertion: Lateral lip of rough surface of femur Action: to adduct limb and extend hip

Biceps Femoris

Origin:Sacrotuberous ligament and ischiatic tuberosity Insertion:Patella and tibia by fascia lata and crural fascia Action: To extend the hip, stifle and hock

Cranial Tibial

Origin: Extensor groove, articular margin of tibia Insertion: plantar surface of base of metatarsals Action: to flex tarsocrural jt, rotate paw laterally so plantar surface faces medially

Deep Digital Flexor

Origin: caudal aspect of proximal 2/3s of tibia Insertion: flexor tubercle on plantar surface of distal phalanges Action: to flex digits and extend tarsus

Deep Gluteal

Origin: body of ilium, ischiatic spine Insertion: cranial aspect of greater trochanter Action: to extend/abduct hip, rotate pelvic limb medially

External Obturator

Origin: ventral surface of pubis/ischium Insertion: Trochanteric Fossa Action: rotate pelvic limb laterally

Fibularis Longus

Origin: lateral condyle of tibia, proximal end of fibula, lateral epicondyle of femur Insertion: fourth tarsal bone, plantar aspect of base of metatarsals Action: to flex tarsus, rotate paw medially so plantar surface faces laterally

Gastrocnemius

Origin: medial and lateral supracondylar tuberosities of femur Insertion: proximal dorsal surface of tuber calcanei Action: to extend tarsus and flex stifle

Gemelli

Origin: lateral surface of ischium Insertion: Trochanteric fossa Action: rotate pelvic limb laterally at hip

Gracilis

Origin: Pelvic Symphysis Insertion: Cranial border of tibia, tuber calceni Action: to adduct limb and extend hip and hock

Iliopsoas

Origin: lumbar vertabrae, cranioventral ilium Insertion: lesser trochanter Action: to flex the hip

Internal Obturator

Origin: symphysis pelvis and dorsal surface of ischium and pubis Insertion: trochanteric fossa of femur Action: rotate pelvic limb laterally at hip

Lateral Digital Flexor

Origin: proximal 1/2 of fibula Insertion: flexor tubercle on plantar surface of distal phalanges Action: to flex digits and extend tarsus

Long Digital Extensor

Origin: extensor fossa of femur Insertion: extensor process's of distal phalanges Action: to extend digits, flex tarsus

Medial Digital Flexor

Origin: adjacent interosseus membrane Insertion: flexor tubercle on plantar surface of distal phalanges Action: to flex digits and extend tarsus

Middle Gluteal

Origin: Crest and gluteal surface of ilium Insertion: Greater Trochanter Action: to extend/abduct hip, rotate pelvic limb medially

Pectineus

Origin: Iliopubic eminence and pubic tubercle Insertion: Medial lip of rough surface of Femur Action: to adduct the limb

Poplitues

Origin: Lateral epicondyle of femur Insertion: proximal 1/3 of caudal surface of tibia Action: rotate leg medially

Quadratus Femoris

Origin: ventral surface of caudal part of ischium Insertion: Intertrochanteric crest Action: to extend hip and rotate pelvic limb laterally

Quadriceps Femoris

Origin: ilium, proximal femur Insertioin: tibial tuberosity Action: to extend stifle/ flex hip
