Document Summary

What do these muscles do: originate from the sacrum and insert onto the femur and it band, cross hip joint, act on the femur to allow, extension, abduction, lateral and medial rotation. It band spans from ilium to just below knee. Runners feel sore and tight, some people foam roll it. Abducts and medially rotates hip (holds pelvis level in swing phase, or during weight bearing) Superior gluteal nerve: the deepest of the gluteal muscles. Superior gluteal nerve: play essential role in gait/ locomotion, keep pelvis level to stabilize. If left limb is unsupported, (r) medius/ minimus work to tilt (l) pelvis up. Normal muscles pull when left opposite leg, if you paralyze one side, the pelvis tilts down on non-paralyzed side. Med, contralateral hip will drop, weak left gluteus, drop to the right side. Sacral plexus: nerves arise from small branches of plexus. Inferior gemellus: on the bottom, all are lateral rotation of hip.
