    Biceps femoris has an action that flexes leg, and extends the thigh.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    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.

    • E.

      Extends thigh; flexes & abducts leg

    Correct Answer
    C. Adducts thigh; flexes & adducts leg
    Explanation
    The action of the gracilis muscle is to adduct the thigh and to flex and adduct the leg. The gracilis is a long, thin muscle located in the inner thigh. It originates from the pubic bone and inserts on the medial surface of the tibia. When it contracts, it pulls the thigh inward toward the body's midline (adduction) and also helps bend the knee (flexion). Additionally, it assists in bringing the leg closer to the midline (adduction of the leg). These actions are important for movements such as stabilizing the hip and knee, walking, and performing motions that require bringing the legs together.

    Explanation
    The peroneus longus muscle inserts at the first metatarsal bone and the first (medial) cuneiform bone. This insertion allows the muscle to perform its functions of plantar flexion and eversion of the foot, as well as helping to maintain the transverse arch of the foot. Originating from the upper part of the lateral surface of the fibula and the lateral condyle of the tibia, the peroneus longus travels down the leg, crosses under the foot, and attaches to these bones, providing stability and support during walking, running, and other movements.

    What is the origin of the Extensor digitorum longus?

    • A.

      Tibia (lateral condyle)

    • B.

      Fibula (posterior surface)

    • C.

      Tibia (second distal third)

    • D.

      Fibula (distal fourth)

    • E.

      Femur (condyles)

    Correct Answer
    A. Tibia (lateral condyle)
    Explanation
    The extensor digitorum longus muscle originates from the lateral condyle of the tibia, the anterior surface of the fibula, and the interosseous membrane. This muscle is located in the anterior compartment of the lower leg and is responsible for extending the toes (except the big toe) and dorsiflexing the foot at the ankle. Its origin points on the lateral condyle of the tibia and the fibula provide the leverage needed for these actions, playing an essential role in walking, running, and maintaining balance by lifting the toes and foot upwards.

    What is the origin of the semitendinosus?

    • A.

      Ischium (tuberosity)

    • B.

      Femur (linea aspera)

    • C.

      Ilium (anterior inferior spine)

    • D.

      Coxal (anterior, superior)

    Correct Answer
    A. Ischium (tuberosity)
    Explanation
    The origin of the semitendinosus muscle is the ischial tuberosity of the pelvis. The semitendinosus is one of the three muscles that make up the hamstring group, located at the back of the thigh. This muscle extends the thigh at the hip joint and flexes the leg at the knee joint. The ischial tuberosity, also known as the "sit bone," provides a strong anchor point for the semitendinosus, allowing it to generate the necessary force for these movements. This muscle is crucial for activities such as walking, running, and jumping, where both hip extension and knee flexion are required.

    What muscle in (green) permits crossing of legs tailor fashion?

    • A.

      Quadricepts femoris group

    • B.

      Rectus femoris

    • C.

      Sartorius

    • D.

      Hamstring Group

    • E.

      Semimembranosus

    Correct Answer
    C. Sartorius
    Explanation
    The sartorius muscle, often highlighted in green in anatomical diagrams, permits the crossing of legs in a tailor fashion. The sartorius is the longest muscle in the human body, running obliquely across the front of the thigh from the anterior superior iliac spine to the medial surface of the tibia at the pes anserinus. This muscle is involved in flexing, abducting, and laterally rotating the thigh at the hip joint, as well as flexing the leg at the knee joint. These combined actions allow a person to sit cross-legged, as tailors traditionally do.

    Rate this question:

  • 31. 

    The insertion of the sartorius muscle is the fibula (medial surface of upper end of shaft).

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The insertion of the sartorius muscle is not on the fibula. Instead, it inserts on the medial surface of the upper part of the tibia. Specifically, the sartorius muscle attaches at the pes anserinus, which is a common tendon area for three muscles: sartorius, gracilis, and semitendinosus. This insertion allows the sartorius to perform its functions of flexing, abducting, and laterally rotating the thigh at the hip joint, as well as flexing the leg at the knee joint. The combined actions of these movements enable complex leg motions, such as sitting cross-legged.

    Calf strains may be minor or very severe and are typically graded as follows:
    • _____ _____ Calf Strain: The muscle is stretched causing some small micro tears in the muscle fibers. Full recovery takes approximately two weeks.

    • A.

      Grade 1

    • B.

      Grade 2

    • C.

      Grade 3

    • D.

      Grade 4

    • E.

      Grade 5

    Correct Answer
    A. Grade 1
    Explanation
    A Grade 1 Calf Strain is characterized by the muscle being stretched, causing some small micro tears in the muscle fibers. This is the least severe type of calf strain and typically results in mild discomfort and minimal loss of strength or mobility. Full recovery from a Grade 1 calf strain usually takes approximately two weeks with proper rest, ice, compression, and elevation (RICE) and gentle stretching and strengthening exercises. This grading helps in determining the appropriate treatment and recovery time needed for muscle strains, with Grade 1 being the mildest and Grade 3 being the most severe.

    • E.

      Grade 5

    Correct Answer
    B. Grade 2
    Explanation
    In a Grade 2 Calf Strain, there is partial tearing of muscle fibers. This type of strain is more severe than a Grade 1 strain and typically results in moderate pain, swelling, and a noticeable decrease in muscle strength and mobility. Full recovery from a Grade 2 calf strain generally takes approximately 5-8 weeks. During this period, treatment includes rest, ice, compression, and elevation (RICE), along with physical therapy to restore strength and flexibility. Proper rehabilitation is essential to prevent further injury and ensure complete healing of the muscle fibers.

    • E.

      Grade 5

    Correct Answer
    C. Grade 3
    Explanation
    A Grade 3 Calf Strain is the most severe type of calf strain, involving a complete tearing or rupture of muscle fibers in the lower leg. This level of injury results in significant pain, swelling, and a substantial loss of muscle function and strength. Full recovery from a Grade 3 calf strain can take 3-4 months, and in some cases, surgery may be required to repair the torn muscle. Rehabilitation will typically include an extended period of rest, physical therapy to regain strength and flexibility, and gradual reintroduction to physical activity to ensure proper healing and prevent re-injury.
