Lecture 19, Muscles of The Anterior Thigh Flashcards
Pectineus
adducts and flexes hip joint; assists with medial rotation of hip joint (femoral nerve - L2, L3) may also recieve a branch from obturator nerve
Sartorius
flexes, abducts and laterally rotates hip joint; flexes knee joint (femoral nerve - L2-L3)
Ilioposoas (psoas major/iliacus)
Acting conjointly in flexing hip joint and in stabilizing this joint; psoas major is also a postural muscle that helps control deviation of the trunk and is active during standing (psoas major - anterior rami of lumbar nerves (L1, L2, L3) ilacus - femoral nerve (L2,L3))
Rectus femoris
extend knee joint; the rectus femoris is also stabilzing the hip joint; helps the ilipsoas flex the hip joint (femoral nerve)
