(sem'ē-mem'bră-nō'sŭs mŭs'ĕl)
Origin, tuberosity of ischium; insertion, medial condyle of tibia and by membrane to tibial collateral ligament of knee joint, popliteal fascia, and via its reflected tendon of insertion (oblique popliteal ligament) lateral condyle of femur; action, flexes knee and rotates leg medially when knee is flexed, and contributes to the stability of extended knee by making capsule of knee joint tense; nerve supply, tibial.
