Excerpt

The muscles of the femoral region of the lower limb are divided into three compartments. The anterior or extensor, medial or adductor and posterior or flexor compartments. Each compartment is separated from the others by intermuscular septa that run from the fascia lata to the linea aspera of the femur. The anterior compartment includes pectineus, iliopsoas, psoas minor, iliacus, sartorius and the quadriceps. These muscles arise from the hip, spine and proximal femur. The medial compartment is made up of the adductor magnus, adductor longus, adductor brevis, gracilis and obturator externus. These muscles originate near the anteroinferior external surface of the bony pelvis and insert at the linea aspera. The posterior compartment is made up of a group of muscles called the hamstrings, including semitendinosus, semimembranosus and biceps femoris.[1][2][3]
