Editing Quadriceps (section)

===Other muscles===
There is a small fifth muscle of the quadriceps complex—the [[articularis genus muscle]]—that is not often included.

In addition, [[cadaver]] studies have confirmed the presence of a sixth muscle, the [[Tensor vastus intermedius muscle|tensor vastus intermedius]].<ref name="Grob_2016">{{cite journal|last1=Grob|first1=K|last2=Ackland|first2=T|last3=Kuster|first3=MS|last4=Manestar|first4=M|last5=Filgueira|first5=L|title=A newly discovered muscle: The tensor of the vastus intermedius|journal=Clinical Anatomy|date=6 January 2016|volume=29|issue=2|pages=256–263|doi=10.1002/ca.22680|pmid=26732825|s2cid=38157592|url=http://doc.rero.ch/record/258954/files/fil_ndm.pdf}}</ref> While this muscle has a variable presentation, it consistently originates at the proximal femur, runs between the vastus lateralis and vastus intermedius muscles, and inserts distally at the medial aspect of the patellar base.<ref name="Grob_2016" /> Historically considered a part of the vastus lateralis muscle, the tensor vastus intermedius muscle is innervated by an independent branch of the [[femoral nerve]] and its tendinous belly can be separated from the vasti lateralis and intermedius muscles in most cases.<ref name="Grob_2016" />
