Which hamstring is described as 'straight leg hamstring' and closer to the knee?

• A. Proximal hamstring
• B. Distal hamstring
• C. Biceps femoris
• D. Semimembranosus

Answer: (B)

Directional terms tell us where a structure sits along the limb. The hamstrings stretch from the hip down to the knee, so the part closest to the knee is the distal portion. When the leg is straight, that distal portion is the one most associated with the “straight leg” description. So the distal hamstring is the best fit because it denotes the region near the knee. Proximal hamstring would be toward the hip, and the other two options are specific muscles rather than a location along the hamstring.
