Variations
Slips of origin from the outer end of the inguinal ligament, the notch of the ilium, the ilio-pectineal line or the pubis occur.
The muscle may be split into two parts, and one part may be inserted into the fascia lata, the femur, the ligament of the patella or the tendon of the Semitendinosus.
The tendon of insertion may end in the fascia lata, the capsule of the knee-joint, or the fascia of the leg.
The muscle may be absent (Scott-Conner, Carol E. H.; David L. Dawson (2003). Operative Anatomy. Lippincott Williams & Wilkins. ISBN 0-7817-3529-7. http://books.google.com/books?id=06GvkEYPg20C. p.606).

Famous quotes containing the word variations:
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
