Session SixThigh (Compartments)

•Posterior Compartment•Anterior Compartment•Medial Compartment

Thigh by deep fascia

( fascia lata ) divided in

to three compartments

and form anatomical

spaces (femoral triangle

and adductor canal ).

Psoas major Posterior abdominal wall (lumbar transverse processes, intervertebral discs, and adjacent bodies from T12 toL5

Lesser trochanter of femur

Anterior rami L1,L2,L3

Flexes the thigh at the hip joint

Iliacus Posterior abdominal wall (iliac fossa)

Lesser trochanter of femur

Femoral nerve [L2,L3]

Flexes the thigh at the hip joint

Sartorius Anterior superior iliac spine

Anterior surface of tibia just inferolateral to tibial tuberosity

Femoral nerve [L2,L3]

Flex, Abd, & Lat.rotation the thigh at the hip joint and flexes the leg at the knee joint

Muscles of the anterior compartment of thigh (continue)

Muscle Origin Insertion Innervation Function

Rectus femoris

Straight head originates from the anterior inferior iliac spine; reflected head originates from the ilium just superior to the acetabulum

Quadriceps femoris tendon

Femoral nerve [L2,L3,L4]

Flexes the thigh at the hip joint and Extends the leg at the knee joint

Vastus medialis

Medial part of intertrochanteric line, Spiral line, medial lip of the linea aspera, medial supracondylar line of femur

Quadriceps femoris tendon and medial border of patella

Femoral nerve [L2,L3,L4]

Extends the leg at the knee joint

Vastus intermedius

Upper two-thirds of anterior and lateral surfaces of femur

Quadriceps femoris tendon and base of patella

Femoral nerve [L2,L3,L4]

Extends the leg at the knee joint

Vastus lateralis

Lateral part of intertrochanteric line, margin of greater trochanter, lateral margin of gluteal tuberosity, lateral lip of the linea aspera

Quadriceps femoris tendon and lateral margin of patella

Muscle Origin Insertion Innervation Function

Biceps femoris

Long head-inferomedial part of the upper area of the ischial tuberosity; short head-lateral lip of linea aspera

Head of fibula Sciatic nerve [L5 to S2]

Flexes leg at knee joint; extends and laterally rotates thigh at hip joint and laterally rotates leg at knee joint

Semitendinosus

Inferomedial part of the upper area of the ischial tuberosity

Medial surface of proximal tibia

Sciatic nerve [L5 to S2]

Flexes leg at knee joint and extends thigh at hip joint; medially rotates the thigh at the hip joint and leg at the knee joint

Semimembranosus

Superolateral impression on the ischial tuberosity

Groove and adjacent bone on medial and posterior surface of medial condyle of tibia

Sciatic nerve [L5,S1,S2]

Flexes leg at knee joint and extends thigh at hip joint; medially rotates thigh at the hip joint and leg at the knee joint
