 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 |
| Semitendinosus | Origin: Ischiatic Tuberosity Insertion: disto cranial border of Tibia, medial border of Tibia, and Tuber Calceni Action: To extend the Hip and Hock |
| Semimembranosus | Origin: Ischiatic Tuberosity Insertion: Rough surface of Femur, medial condyle of Tibia Action: To extend the Hip, Stifle |
| Sartorius | Origin: Cranial crest of Ilium, cranial ventral iliac spine Insertion: cranial part-Patella; caudal part-cranial border of tibia Action: to flex hip, extend stifle |
| Gracilis | Origin: Pelvic Symphysis Insertion: Cranial border of tibia, tuber calceni Action: to adduct limb and extend hip and hock |
| Pectineus | Origin: Iliopubic eminence and pubic tubercle Insertion: Medial lip of rough surface of Femur Action: to adduct the limb |
| 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 |
| Tensor Fasciae Latae | Origin: Tuber Coxae, ilium Insertion: Fascia Lata Action: flex hip, extend stifle |
| Superficial Gluteal | Origin: lateral border of sacrum, 1st caudal vertabrae, cranial dorsal iliac spine Insertion: third Trochanter Action: to extend hip and abduct limb |
| Middle Gluteal | Origin: Crest and gluteal surface of ilium Insertion: Greater Trochanter Action: to extend/abduct hip, rotate pelvic limb medially |
| Deep Gluteal | Origin: body of ilium, ischiatic spine Insertion: cranial aspect of greater trochanter Action: to extend/abduct hip, rotate pelvic limb medially |
| Internal Obturator | Origin: symphysis pelvis and dorsal surface of ischium and pubis Insertion: trochanteric fossa of femur Action: rotate pelvic limb laterally at hip |
| Gemelli | Origin: lateral surface of ischium Insertion: Trochanteric fossa Action: rotate pelvic limb laterally at hip |
| Quadratus Femoris | Origin: ventral surface of caudal part of ischium Insertion: Intertrochanteric crest Action: to extend hip and rotate pelvic limb laterally |
| External Obturator | Origin: ventral surface of pubis/ischium Insertion: Trochanteric Fossa Action: rotate pelvic limb laterally |
| Quadriceps Femoris | Origin: ilium, proximal femur Insertioin: tibial tuberosity Action: to extend stifle/ flex hip |
| Iliopsoas | Origin: lumbar vertabrae, cranioventral ilium Insertion: lesser trochanter Action: to flex the hip |
| 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 |
| Long Digital Extensor | Origin: extensor fossa of femur Insertion: extensor process's of distal phalanges Action: to extend digits, flex tarsus |
| 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 |
| Superficial Digital Flexor | Origin: lateral supracondylar tuberosity of femur Insertion: Tuber calcanei, bases of middle phalanges Action: to flex 1st 2 digital jts, flex stifle, extend tarsus |
| 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 |
| 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 |
| Medial Digital Flexor | Origin: adjacent interosseus membrane Insertion: flexor tubercle on plantar surface of distal phalanges Action: to flex digits and extend tarsus |
| Poplitues | Origin: Lateral epicondyle of femur Insertion: proximal 1/3 of caudal surface of tibia Action: rotate leg medially |
