Document Summary

Contains the iliacus, psoas major, and psoas minor. While the muscles have separate origins they have the same insertion point at the lesser trochanter. Innervated by the lumbar and femoral nerves. One of the largest, heaviest, and most powerful muscles in the human body. Responsible for hip extension and lateral rotation. Innervated by: inferior gluteal nerve (not important info for final exam) Abducts flexed hip (not important for test because only anatomical position on exam) Innervated by: piriformis nerve (not important info for final exam) Responsible for abduction and medial rotation of hip. Innervated by: superior gluteal nerve (not important info for final exam) Innervated by the obturator and sciatic nerves. Due to the weakness of this muscle it is never an agonist. Vastus lateralis, intermedius, medialis, and rectus femoris. Rectus femoris runs overtop of the vasti muscles. All have a common point of insertion at the quadriceps tendon. Collectively one of the largest and strongest muscles in the body.
