Summary of Muscles in the Femoral Triangle
SartoriusOrigin Anterior superior iliac spine
Insertion Superior aspect medial surface of tibial shaft
Action Flexes, adducts and laterally rotates the hip joint and flexes the knee
Nerve Supply Anterior division of femoral nerve (L3, L4)
Blood Supply Femoral artery
Anterior Thigh
Hip FlexorsIliacus
Origin Upper 2/3 of iliac fossa of ilium, lateral aspect of sacrum
Insertion Lesser trochanter inferior aspect
Action Flexes and medially rotates hipNerve Supply Muscular branch of femoral
nerve (L2, L3)Blood Supply Lumbar branch of iliopsoas
branch of internal iliac artery
Hip FlexorsPsoas
Origin Anterior surfaces and lower borders of transverse processes of L1 - L5 and bodies and discs of T12 - L5
Insertion Lesser trochanterAction Flexes and medially rotates the
hipNerve Supply Anterior primary rami L1,2 Blood Supply Lumbar branch of iliopsoas
branch of internal iliac artery
Anterior Thigh
PectineusOrigin Pectineal surface of the pubisInsertion Pectineal line of femur below lesser
trochanterAction Adducts the thigh, flexes hip jointNerve Supply Femoral nerve & some innervation
from the obturator nerve (L2, L3, L4)
Blood Supply Medial circumflex femoral branch of femoral artery and obturator artery
Adductor LongusOrigin Anterior surface of body of pubis,
just lateral to pubic symphysisInsertion Middle third of linea aspera,
between the more lateral adductor magnus and brevis insertions and the more medial origin of the vastus medialis
Action Adducts, flexes and medially rotates the hip joint
Nerve Supply Anterior division of obturator nerve (L2, L3, L4)
Blood Supply Obturator artery and medial circumflex femoral artery
Anterior Thigh
