Document Summary

The muscular system: muscles of the pelvic girdle and lower. 5 different groups, in picture only 4 is seen, one is big enough to be separated into 2 subgroups. Nerves that innervate come from lumbar or sacral plexuses. 2 main nerves in lumbar region femoral and obtruator nerve (runs through obturator foramen) Sciatic nerve- like an extension cord, and as thick. Sciatica continuous pressure placed in this nerve because it is so big, structures it innervates begin to tingle and get sore. Common - further braches to come, common artery that will branch into further arteries. Vastus intermedius- originates off the anterior femur. Very few insertion points on the anterior femur , few attachments. On the posterior side very different- lots of attachments. Assign an origin for a muscle on pelvis or femur, move towards insertion point you need to consider where it attaches on femur, what the muscle will do.
