quad·ri·ceps fem·o·ris mus·cle

(kwahd'ri-seps fem'ŏr-is mŭs'ĕl)
Origin, by four heads: rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis; insertion, patella, and thence by ligamentum patellae to tuberosity of tibia; action, extends leg; flexes thigh by action of rectus femoris; nerve supply, femoral.
Synonym(s): musculus quadriceps femoris [TA] , quadriceps muscle of thigh.
