| What travels through the adductor hiatus? | Femoral artery/vein |
| origin and insertion of gracilis | O: inferior ramus of anterior pubis I: medial proximal tibia |
| action of gracilis | adduction of femur, assists flexion of knee, assists medial rotation of tibia when knee is flexed |
| innervation of gracilis | obturator n (L2,3) |
| origin and insertion of the gluteus maximus | o: posterior sacrum, ilium (via sacrotuberous ligament), posterior (superior) gluteal line of ilium I: gluteal tuberosity of femur, IT tract (attaching to lateral condyle of tibia) |
