Document Summary

Thigh = hip to the knee (3 compartments) Lower leg = knee to the ankle (3 compartments) Made of 4 compartments, one is split up into two. Lumbar plexus: spinal roots from lumbar region coming out to form plexus: Very large nerve: common fibular nerve, tibial nerve. Combination of three muscles: psoas (actually two muscles: major & minor) Run down to the iliacus muscle: iliacus. Most powerful hip flexor in the body. Remember: name comes from tailor crosses the lower limb: crosses the thigh (crosses 2 joints) Insertion: medial tibia: medial tibia = goose"s foot , 3 tendons attached side by side, 3 muscles insert here, rectus femoris. Origin: aiis (anterior inferior iliac spine: runs down, incorporates the patella and joins up to the rest of the quadriceps muscles. Split up into two groups: gluteus maximus (group 1) Origin: most posterior portion of iliac crest: runs all the way down the sacrum.
