3 PPosterior Compartment AAnterior Compartment MMedial Compartment Compartments of the Thigh

4 Thigh by deep fascia( fascia lata ) divided in to three compartments and form anatomical spaces (femoral triangle and adductor canal ). Thigh

5 Post. Compartment Muscles Arterial Supply Nerve Supply Hamstring: 1.SSemitendinosus 2.SSemimembranosus 3.BBiceps femoris Profonda femoris: Branch of femoral artery Sciatic nerve Sciatic nerve is formed of (L4, L5, S1, S2, S3) branches of sacral plexus

6 Back Muscles of the posterior compartment of thigh MuscleOriginInsertionInnervationFunction Biceps femoris Long head-inferomedial part of the upper area of the ischial tuberosity; short head-lateral lip of linea aspera Head of fibulaSciatic nerve [L5 to S2] Flexes leg at knee joint; extends and laterally rotates thigh at hip joint and laterally rotates leg at knee joint Semitendi nosus 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 Semimem branosus 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
