Biceps femoris has an action that flexes leg, and extends the thigh.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true. The biceps femoris, one of the muscles in the hamstring group located at the back of the thigh, has dual actions: it flexes the leg at the knee joint and extends the thigh at the hip joint. This muscle has two heads – the long head originates from the ischial tuberosity of the pelvis, and the short head originates from the femur. When the biceps femoris contracts, it pulls the leg backward (extension of the thigh) and bends the knee (flexion of the leg). These actions are crucial for movements like walking, running, and jumping.Rate this question:
