    The labrum aids in lubrication like meniscus of knee and serves to protect the bone

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The labrum is a ring of cartilage that lines the socket of the shoulder joint. It helps to deepen the socket and provide stability to the joint.

    During flexion, the femoral condyles roll posteriorly, and the ACL becomes taut causing the condyles to glide anteriorly

    • True

    • False

    Correct Answer
    A. True
    Explanation
    During flexion of the knee joint, the femoral condyles roll posteriorly, which means they move towards the back of the knee joint. At the same time, the anterior cruciate ligament (ACL) becomes taut or tight. This tension in the ACL causes the femoral condyles to glide anteriorly, meaning they move towards the front of the knee joint. This movement helps to stabilize the knee joint during flexion and prevents excessive forward movement of the tibia. Therefore, the statement is true.

    • A or c

    Correct Answer
    A. 30
    Explanation
    The orientation of the glenoid fossa places true abduction at 30 degrees anterior to the frontal plane. This means that when the arm is raised to the side, it will be angled 30 degrees forward from the frontal plane of the body. This position allows for optimal movement and stability of the shoulder joint during abduction.

    Which of the following are true?

    • The transverse ligament connects the lateral and medial meniscus anteriorly

    • The meniscopatellar ligament runs from the inferolateral edges of the patella to the lateral borders of each meniscus and pulls the menisci forward with extension

    • The alar fold runs from the lateral borders of the patella to the medial and lateral aspects of the femoral condyles keeping the patella in contact with the femur

    • The infrapatellar fold is formed by attachments of th epatella fat pad and tendons via a fibroadipose band lying in intercondylar notch. It acts a stop gap as it is compressed by patella tendon in full flexion

    • All of the above are true

    Correct Answer
    A. All of the above are true
    Explanation
    The correct answer is "all of the above are true." This means that all of the statements provided in the question are correct. The transverse ligament does connect the lateral and medial meniscus anteriorly, the meniscopatellar ligament does run from the inferolateral edges of the patella to the lateral borders of each meniscus and pulls the menisci forward with extension, the alar fold does run from the lateral borders of the patella to the medial and lateral aspects of the femoral condyles keeping the patella in contact with the femur, and the infrapatellar fold is indeed formed by attachments of the patella fat pad and tendons via a fibroadipose band lying in the intercondylar notch, acting as a stop gap when compressed by the patella tendon in full flexion.

    The labrum attaches to the capsule where

    • Superiorly, inferiorly, and superiorly to the long head of the biceps

    • Superior, lateral, medial

    • Supeirorly, laterally, inferiorly to the anattomical neck

    • None of the above

    • A or c

    Correct Answer
    A. Superiorly, inferiorly, and superiorly to the long head of the biceps
    Explanation
    The labrum attaches to the capsule superiorly, inferiorly, and superiorly to the long head of the biceps. This means that the labrum is connected to the capsule in three locations: above, below, and above the long head of the biceps tendon. This attachment helps to stabilize the shoulder joint and provide support to the biceps tendon during movement.

    Which of the following are true

    • The oblique ligament strengthen the lateral capsule

    • The oblique ligament strengthens the medial capsule

    • The arcuate or y ligament strengthens the lateral capsule

    • The arcuate or y ligament strengthen the medial capsule

    Correct Answer(s)
    A. The oblique ligament strengthens the medial capsule
    A. The arcuate or y ligament strengthens the lateral capsule
    Explanation
    The oblique ligament strengthens the medial capsule because it connects the medial meniscus to the medial condyle of the tibia, providing stability to the inner side of the knee joint. On the other hand, the arcuate or y ligament strengthens the lateral capsule by attaching the lateral meniscus to the head of the fibula, providing stability to the outer side of the knee joint. Therefore, the given answer is correct.
