N: Femoral Nerve
Vastus Intermedius
Quad-Extend the stifle
O: Lateral part of proximal 1/4 of femur
I: Tibial tuberosity
N: Femoral nerve
Vastus Lateralis
Quad-Extend the stifle
O: Proximal lateral femur
I: Tibial tuberosity
N: Femoral nerve
Rectus Femoris
Quads-Extend the stifle and Flex the hip
O: Ilium, cranial to the acetabulum
I: Tibial tuberosity
N: Femoral nerve
Semimembranosus
Extend the hip; The part inserting on the tibia can flex or extend the stifle depending on position of limb
O: Ischiatic tuberosity
I: Distal medial femur and proximal end of tibia
N: Sciatic nerve
Semitendinosus
Extend the hip, flex the stifle, and extend the tarsus
O: Ischiatic tuberosity
I: Medial surface of body of tibia and tuber calcanei
N: Sciatic nerve
Gracilis
Adduct the limb, flex stifle, extend hip and tarsus
O: Pubic symphysis
I: Cranial border of tibia and tuber calcaneus w/ semitend
Tensor Fasciae Latae
Tense the femoral fascia, flex hip, extend stifle
O: Tuber coxae and adjacent ilium
I: Lateral femoral fascia
Sartorius-2 heads
Flex hip (both heads), CRANIAL extend stifle, CAUDAL flex stifle
O: CRANIAL medial crest of ilium, CAUDAL cranial ventral iliac spine
I: CRANIAL patella w/ quads, CAUDAL cranial border of tibia w/ gracilis
N: Femoral nerve
Biceps femoris
Extend the hip, stifle, and tarsus
O: Sacrotuberous ligament and ischiatic tuberosity
I: By way of fascia lata, to patella, patellar ligament, and cranial border of tibia; by means of crural fascia the tuber calcanei
N: Sciatic nerve
