Which of the Following Muscles Belongs to the Group Known

Question

Which of the following muscles belongs to the group known as "hamstrings"?
A) semitendinosus and rectus femoris
B) semimembranosus, biceps femoris, and gracilis
C) biceps femoris, gracilis, and sartorius
D) semitendinosus, semimembranosus, and biceps femoris
E) adductor magnus, semimembranosus, and rectus femoris

Accepted Answer

The hamstrings group is composed of three muscles: semitendinosus, semimembranosus, and biceps femoris. These muscles are located at the back of the thigh and are responsible for hip extension and knee flexion. Semitendinosus and semimembranosus both originate at the ischial tuberosity (the bony projection at the bottom of the pelvis) and attach to the tibia and fibula bones in the lower leg. Biceps femoris also originates at the ischial tuberosity but attaches to the fibula and lateral condyle of the tibia. Therefore, the correct answer is D.
