    Questions 50 through 53 refer to the figure below of an axial, T2-weighted MRI of the elbow.Which arrow points to the annular ligament? - ProProfs

    Questions 50 through 53 refer to the figure below of an axial, T2-weighted MRI of the elbow.Which arrow points to the annular ligament?

    • C

    • D

    • A

    • B

    Correct Answer
    A. C
    Explanation
    The correct answer is C. In the given figure, the arrow labeled C is pointing to the annular ligament. This ligament is located around the head of the radius bone in the elbow joint. It helps to hold the radius bone in place and allows it to rotate during movements of the forearm.

    Questions 50 through 53 refer to the figure below of an axial, T2-weighted MRI of the elbow.Which arrow points to the pronator teres muscle? - ProProfs

    Questions 50 through 53 refer to the figure below of an axial, T2-weighted MRI of the elbow.Which arrow points to the pronator teres muscle?

    • A

    • B

    • D

    • C

    Correct Answer
    A. B
    Explanation
    The arrow pointing to B indicates the pronator teres muscle. This muscle is located in the forearm and plays a role in pronating the forearm (rotating it so that the palm faces downward). It is situated near the elbow joint, which is why it can be seen in the axial MRI image of the elbow.

    Which articulations of the elbow create the pivot joint that aids in supination and pronation of the elbow?

    • Radiohumeral and ulnohumeral

    • Ulnohumeral and trochlear

    • Radioulnar and ulnohumeral

    • Radiohumeral and radioulnar

    Correct Answer
    A. Radiohumeral and radioulnar
    Explanation
    The correct answer is Radiohumeral and radioulnar. The elbow joint consists of two articulations: the radiohumeral joint, which is formed between the radius and humerus, and the radioulnar joint, which is formed between the radius and ulna. These two articulations work together to allow for the movements of supination and pronation of the elbow.

    The supraspinatus muscle:

    • Pulls the head of the humerus downward and laterally into the glenoid fossa up and medial

    • Originates in the supraspinous fossa and inserts at the greater tubercle of the humerus

    • Inserts at the scapular spine and originates at the greater tubercle of the humerus

    • Originates at the clavicle and inserts on the humerus

    Correct Answer
    A. Originates in the supraspinous fossa and inserts at the greater tubercle of the humerus
    Explanation
    The supraspinatus muscle originates in the supraspinous fossa and inserts at the greater tubercle of the humerus. This means that it starts from a specific area in the scapula called the supraspinous fossa and attaches to a specific part of the humerus called the greater tubercle. This information helps us understand the location and function of the supraspinatus muscle in the shoulder joint.

    What covers the articulating surfaces in synovial joints?

    • Joint capsule

    • Hyaline cartilage

    • Bursa

    • Synovial membrane

    Correct Answer
    A. Hyaline cartilage
    Explanation
    Hyaline cartilage covers the articulating surfaces in synovial joints. This type of cartilage is smooth and provides a low-friction surface for the bones to move against each other. It also helps to absorb shock and distribute pressure evenly across the joint. The hyaline cartilage acts as a protective cushion, preventing the bones from rubbing against each other and reducing wear and tear on the joint.

    What ligament in the elbow attaches to the annular ligament?

    • Radial collateral

    • Biceps

    • Supinator

    • Ulnar collateral

    Correct Answer
    A. Radial collateral
    Explanation
    The correct answer is the radial collateral ligament. This ligament in the elbow attaches to the annular ligament. It helps to stabilize the joint and prevent excessive side-to-side movement.
