APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The semitendinosus, semimembranosus, and biceps femoris muscles comprise the hamstring muscle group. Beginning at the pelvis and running posteriorly along the length of the femur, the majority of muscles within the hamstring complex cross both the femoroacetabular and tibiofemoral joints.

Detailed explanation-2: -Hamstrings: The hamstrings are a group of three muscles (biceps femoris, semimembranosus, and semitendinosus) that originate from the ischium of the pelvis bone in the back of the hip (“sit bone”) and then extend down the back of the thigh, inserting on the top of the lower leg (tibia and fibula) behind the knee.

Detailed explanation-3: -Semimembranosus, closest to the middle of your body. This hamstring flexes your knee joint, extends your thigh at your hip and offers medial rotation for your hip and lower leg. Semitendinosus, between the semimembranous and the biceps femoris. The function of this hamstring matches that of the semimembranosus.
