Document Summary

Remember to focus on the primary functions. Thigh (hip to knee) 3 compartments. Lower leg (knee to ankle) 3 compartments. Multiple innervation paths causing signal redundancy allowing there to still be partial innervation when an injury occurs. Sciatica compression of sciatic nerve due to excessive sitting. Iliopsoas muscle: primary muscle in this region, located on the anterior hip & crosses the joint, combination of two (technically 3) muscles, pscoas (2 muscles major and minor grouped as 1) Origin transverse process of lumbar vertebrae. Run down and joins to form a muscle belly with the iliacus: iliacus. Sartorius: crosses two joints & thigh, origin - anterior superior iliac spine (asis, insertion medial tibia, innervation femoral nerve. Rectus femoris: often also grouped as a quadriceps muscle, origin - anterior inferior iliac spine (aiis, insertion tibia tuberosity (incorporates patella & patellar lig. , function hip flexion, innervation femoral nerve.
