Muscles of the Anterior Thigh: Flexors of the Hip Joint
Muscle Origin Insertion Innervation Main Action
Pectineus Superior ramus of pubis Pectineal line of femur,
just inferior to lesser
trochanter
Femoral nerve (L2, L3);
may receive a branch
from obturator nerve
Adducts and flexes
thigh; assists with
medial rotation of thigh
Iliopsoas
Psoas major
Sides of T12-L5
vertebrae ad discs
between them;
transverse processes of
all lumbar vertebrae
Lesser trochanter of
femur
Anterior rami of lumbar
nerves (L1, L2, L3)
Act conjointly in flexing
thigh at hip joint and in
stabilizing this joint
Psoas minor Sides of T12-L1
vertebrae and
intervertebral disc
Pectineal line,
iliopectineal eminence
via iliopectineal arch
Anterior rami of lumbar
nerves
iliacus Iliac crest, iliac fossa,
ala of sacrum, and
anterior sacroiliac
ligaments
Tendon of psoas major,
lesser trochanter, and
femur distal to it
Femoral nerve
sartorius Anterior superior iliac
spine and superior part
of notch inferior to it
Superior part of medial
surface of tibia
Femoral nerve Flexes, abducts, and
laterally rotates thigh at
hip joint; flexes leg at
knee joint
Muscles of the Anterior Thigh: Extensors of the Knee
Muscle Origin Insertion Innervation Main Action
Quadriceps femoris
Rectus femoris Anterior inferior iliac
spine and ilium superior
to acetabulum
Via common tendinous
(quadriceps tendon) and
independent attachments
to base of patella;
indirectly via patellar
Femoral nerve Extend leg at knee joint;
rectus femoris also
steadies hip joint and
helps iliopsoas flex thigh

thigh
gracilis Body and inferior ramus
of pubis
Superior part of medial
surface of tibia
