Where is the semimembranous muscle inserted?

It is located on the posterior medial aspect of the thigh, deep within the semitendinosus.It begins at the ischial tuberosity of the lower pelvis and ends at medial tibial condyle. Its main movements are knee flexion, hip extension and knee internal rotation.

Which joints does the semimembranosus pass through?

semimembranosus span Hip and Knee and is therefore responsible for multiple movements around the joint.
