| Question | Answer |
|---|---|
| What is the origin of the biceps femoris? | Ischiatic tuberosity and sacrotuberous ligament. |
| What is the insertion of the biceps femoris? | Fascia lata/crural fascia, patella/patellar ligament, cranial tibia, and calcaneal tuber through fascial expansions. |
| What is the action of the biceps femoris? | Extends the hip and hock; cranial part extends the stifle, caudal part flexes it; abducts the limb. |
| What is the origin of the semitendinosus? | Ischiatic tuberosity. |
| What is the insertion of the semitendinosus? | Medial tibial body and calcaneal tuber through crural fascia. |
| What is the action of the semitendinosus? | Extends the hip and hock; flexes the stifle. |
| What is the origin of the semimembranosus? | Ischiatic tuberosity. |
| What is the insertion of the semimembranosus? | Caudomedial femur and medial tibial condyle. |
| What is the action of the semimembranosus? | Extends the hip; cranial portion extends the stifle, caudal portion may flex it; adducts the limb. |
| What is the origin of the sartorius—cranial part? | Iliac crest/cranial iliac region and thoracolumbar fascia. |
| What is the insertion of the sartorius—cranial part? | Patella and fascia of the stifle with rectus femoris. |
| What is the action of the sartorius—cranial part? | Flexes the hip and extends the stifle. |
| What is the origin of the sartorius—caudal part? | Cranial ventral iliac spine and adjacent ventral ilium. |
| What is the insertion of the sartorius—caudal part? | Cranial border of the tibia with gracilis fascia. |
| What is the action of the sartorius—caudal part? | Flexes the hip and flexes the stifle. |
| What is the origin of the gracilis? | Pelvic symphysis. |
| What is the insertion of the gracilis? | Cranial tibia and calcaneal tuber through crural fascia. |
| What is the action of the gracilis? | Adducts the limb, flexes the stifle, and extends the hip/hock. |
| What is the origin of the pectineus? | Iliopubic eminence/prepubic tendon and cranial pubic ligament. |
| What is the insertion of the pectineus? | Distal medial femur/medial lip of the caudal rough surface. |
| What is the action of the pectineus? | Adducts the limb and assists hip flexion. |
| What is the origin of the adductor? | Pelvic symphysis and ventral pubis/ischium. |
| What is the insertion of the adductor? | Caudal surface/rough lines of the femur. |
| What is the action of the adductor? | Adducts the limb and extends the hip. |
| What is the origin of the tensor fasciae latae? | Tuber coxae and adjacent ilium; blends with middle gluteal aponeurosis. |
| What is the insertion of the tensor fasciae latae? | Fascia lata and cranial tibia through the patellar ligament. |
| What is the action of the tensor fasciae latae? | Tenses fascia lata, flexes the hip, and extends the stifle. |
| What is the origin of the superficial gluteal? | Lateral sacrum and first caudal vertebra/sacrotuberous fascia. |
| What is the insertion of the superficial gluteal? | Third trochanter of the femur. |
| What is the action of the superficial gluteal? | Extends and abducts the hip. |
| What is the origin of the middle gluteal? | Iliac crest and gluteal surface of the ilium. |
| What is the insertion of the middle gluteal? | Greater trochanter. |
| What is the action of the middle gluteal? | Powerfully extends and abducts the hip; assists medial rotation. |
| What is the origin of the deep gluteal? | Body of the ilium and ischiatic spine. |
| What is the insertion of the deep gluteal? | Cranial aspect of the greater trochanter. |
| What is the action of the deep gluteal? | Abducts the hip and rotates the limb medially; assists extension. |
