wuri

Semimembranosus tsoka located karkashin cinya semitendinosus. An fara muskulus semimembranosus (semimembranous tsoka) da agara farantin, wanda qunshi dukan saman rabo by attaching cikin sama ɓangare ga ischial tuberosity sa'an nan ta sauka tare da tsakiya (ciki) gefen femur. A karshe (distal) semimembranosus tsoka agara decomposes a ƙananan agara da aka makala a kan uku katako kafa zurfin hankaka ta feet a kan kowane daga cikin cinyoyinsa.
