    The distal end of the quadriceps and the patellar ligament are the same structure.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The distal end of the quadriceps and the patellar ligament are indeed the same structure. The quadriceps muscle is a group of four muscles located in the front of the thigh, and its distal end (lower end) forms the patellar ligament. The patellar ligament connects the patella (kneecap) to the tibia (shinbone), and it is responsible for transmitting the force produced by the quadriceps muscle to the lower leg, allowing for movements such as kicking and jumping. Therefore, it is correct to say that the distal end of the quadriceps and the patellar ligament are the same structure.

    Correct Answer
    A. True
    Explanation
    The psoas major and the iliacus are indeed powerful hip flexors. These muscles work together to flex the hip joint, bringing the thigh towards the abdomen. They are important for movements such as walking, running, and climbing stairs. When these muscles contract, they generate a significant amount of force, allowing for powerful hip flexion. Therefore, the statement that the psoas major and the iliacus are powerful hip flexors is true.

    Extensors are located along the anterior and lateral surfaces and the flexors lie along the posterior and medial surfaces of the leg.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because extensors are indeed located along the anterior and lateral surfaces of the leg, while flexors are located along the posterior and medial surfaces. This is consistent with the anatomical arrangement of muscles in the leg, where extensor muscles are responsible for extending or straightening the leg, and flexor muscles are responsible for flexing or bending the leg.

    The flexors of the knee include the:

    • Biceps Femoris

    • Gracillis

    • Semitendinosus

    • Semimebranous

    • Sartorius

    Correct Answer(s)
    A. Biceps Femoris
    A. Semitendinosus
    A. Semimebranous
    A. Sartorius
    Explanation
    The flexors of the knee are the muscles that help to bend the knee joint. The biceps femoris, semitendinosus, semimembranosus, and sartorius are all muscles that contribute to knee flexion. The biceps femoris is located on the back of the thigh and helps to flex the knee and rotate the leg. The semitendinosus and semimembranosus are both located on the back of the thigh and also assist in knee flexion. The sartorius muscle is located on the front of the thigh and aids in both hip flexion and knee flexion.

    The flexors of the knee considered the hamstrings (biceps femoris, semitendinosus and semimembranosus) product both flexion of the knee and extension at the hip.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the hamstrings, which include the biceps femoris, semitendinosus, and semimembranosus muscles, are responsible for both flexion of the knee and extension at the hip. These muscles work together to allow movements such as bending the knee and bringing the leg backward at the hip joint. Therefore, the statement accurately describes the function of the hamstrings as flexors of the knee and extensors at the hip.

    In the hamstring group, the biceps femoris is on the lateral side of the body and the semitendinosus is more medial.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the biceps femoris is indeed located on the lateral side of the body, while the semitendinosus is positioned more medially within the hamstring group. This anatomical arrangement is consistent with the typical positioning of these muscles in the human body.
