MUSCLE NAME | ORIGIN | INSERTION | ACTION | ||||
Rectus femoris (one of quadriceps muscles) |
|
|
KNEE EXTENSION AND HIP FLEXION | ||||
GLUTEUS MAXIMUS | dorsal ilium, sacrum and coccyx | GLUTEAL TUBEROSITY OF FEMUR | External rotation and extension of the hip joint, supports the extended knee through the iliotibial tract, chief antigravity muscle in sitting and abduction of the hip | ||||

inferior ramus and body of pubis |
MEDIALSURFACE OF TIBIA JUST INFERIOR TO MEDIAL CONDYLE |
flexes knee joint, laterally rotates knee joint (when knee is flexed), extends hip joint (long head only) |
||||
Popliteus TENSOR FASCIA LATAE |
anterior aspect of iliac crest and anterior superior iliac spine |
ILIOTABIAL TRACT |
