The semimembranosus muscle (/ ˌ s ɛ m i ˌ m ɛ m b r ə ˈ n oʊ s ə s /) is the most medial of the three hamstring muscles in the thigh. It is so named because it has a flat tendon of origin. It lies posteromedially in the thigh, deep to the semitendinosus muscle. It extends the hip joint and flexes the knee joint.
semimembranosus: Lower limb, Thigh, Posterior compartment/hamstring ischial tuberosity [11] medial surface of tibia [11] profunda femoris, gluteal artery: sciatic nerve [11] flexes knee, extends hip, medially rotates leg at knee [11] quadriceps femoris: 2 1 gracilis: Lower limb, Thigh/Hip, Medial compartment (adductor muscles) inferior pubic ...
Cell-based models are mathematical models that represent biological cells as discrete entities. Within the field of computational biology they are often simply called agent-based models [1] of which they are a specific application and they are used for simulating the biomechanics of multicellular structures such as tissues. to study the influence of these behaviors on how tissues are organised ...
Semitendinosus and semimembranosus extend the hip when the trunk is fixed; they also flex the knee and medially (inwardly) rotate the lower leg when the knee is bent. The long head of the biceps femoris extends the hip, as when beginning to walk; both short and long heads flex the knee and laterally (outwardly) rotate the lower leg when the ...

The oblique popliteal ligament is formed as a lateral expansion of the tendon of the semimembranosus muscle [2] and represents one of the muscle's five insertions. [citation needed] The ligament blends with the posterior portion of the knee joint capsule. [2] It exhibits a large opening through which nerves and vessels pass. [3]
Presumably there must be some difference in the action. From introspection of my own body it seems that the semimembranosus has more of a knee medial rotation action than does the semitendinosus, but all the references I can find list identical actions for both muscles.

the bursa semimembranosa between the medial collateral ligament and the tendon of the semimembranosus [2] there is one between the tendon of the semimembranosus and the head of the tibia [5] and occasionally there is a bursa between the tendons of the semimembranosus and semitendinosus [5]
