where does the semimenbranosus insert at
Its origin is the ischial tuberosity and it inserts on the medial condyle and nearby margin of tibia; intercondylar fossa of femur and lateral condyle of femur; and the ligament of the popliteal region (at the back of the knee).he semimembranosus helps to extend (straighten) the hip joint and flex (bend) the knee joint. It also helps medially rotate the knee: the tibia medially rotates on the femur when the knee is flexed. Medially rotates the femur when the hip is extended.
