     The marked area on the tagged bone is held in contact with the radial notch of ulna by  what structure? - ProProfs

     The marked area on the tagged bone is held in contact with the radial notch of ulna by  what structure?

    • Radial collateral ligament

    • Biceps brachii tendon

    • Ulnar collateral ligament

    • Bicipital aponeurosis

    • Anular ligament of radius

    Correct Answer
    A. Anular ligament of radius
    Explanation
    The correct answer is the Anular ligament of radius. The anular ligament of radius is a strong band of fibrous tissue that encircles the head of the radius, holding it in place against the radial notch of the ulna. This ligament allows for smooth rotation of the radius during pronation and supination of the forearm.

     A patient has suffered a stab wound at the tagged area.  As a result of damage of the underlying neurovascular structures,  the patient will most likely have difficulty performing which of the following movements? - ProProfs

     A patient has suffered a stab wound at the tagged area.  As a result of damage of the underlying neurovascular structures,  the patient will most likely have difficulty performing which of the following movements?

    • Abducting the thumb

    • Flexing digit III-IV metacarpophalangeal joint

    • Flexing the thumb

    • Flexing digit III-IV distal interphalangeal joint

    • Opposing the thumb

    Correct Answer
    A. Flexing digit III-IV metacarpophalangeal joint
    Explanation
    The correct answer is flexing digit III-IV metacarpophalangeal joint. This is because the metacarpophalangeal joint is responsible for flexing the fingers, and damage to the neurovascular structures underlying this joint would result in difficulty performing this movement. The other movements listed, such as abducting the thumb, flexing the thumb, flexing digit III-IV distal interphalangeal joint, and opposing the thumb, are not directly affected by damage to the neurovascular structures underlying the metacarpophalangeal joint.

     The hand of the patient in Question 3 is most likely to be diagnosed with the following condition:

    • Hand of Benediction deformity

    • Claw Hand deformity

    • Wrist Drop deformity

    • Ape Hand deformity

    • Dupuytren contracture

    Correct Answer
    A. Claw Hand deformity
    Explanation
    The hand of the patient in Question 3 is most likely to be diagnosed with Claw Hand deformity. This condition is characterized by the inability to fully extend the fingers due to a weakness or paralysis of the muscles that control finger extension. This results in a claw-like appearance of the hand, with the fingers flexed at the joints closest to the fingertips and extended at the joints closest to the palm. This deformity can be caused by nerve damage, such as in conditions like ulnar nerve palsy or radial nerve palsy.

     Identify the type of synovial joint that is represented by the tagged articular area. - ProProfs

     Identify the type of synovial joint that is represented by the tagged articular area.

    • Plane

    • Condylar

    • Saddle

    • Pivot

    • Hinge

    Correct Answer
    A. Saddle
    Explanation
    The correct answer is "Saddle" because a saddle joint is a type of synovial joint in which the articular surfaces are shaped like a saddle. This type of joint allows for movement in two planes, making it highly mobile and flexible. The articular area represented in the question is likely shaped like a saddle, which is characteristic of a saddle joint.

     Identify the tagged structure: - ProProfs

     Identify the tagged structure:

    • Deep branch of radial nerve

    • Superficial branch of radial artery

    • Superficial palmer arch

    • Recurrent branch of median nerve

    • Superficial branch of radial nerve

    Correct Answer
    A. Recurrent branch of median nerve
    Explanation
    The tagged structure in this list is the "Recurrent branch of median nerve".

     Identify the tagged structure: - ProProfs

     Identify the tagged structure:

    • Flexor pollicis longus tendon

    • Median nerve

    • Extensor indicis tendon

    • Ulnar nerve

    • Flexor pollicis brevis tendon

    Correct Answer
    A. Flexor pollicis longus tendon
    Explanation
    The correct answer is the Flexor pollicis longus tendon. The other options listed are different structures or nerves that are not related to the Flexor pollicis longus tendon.

    The proximal attachment of the tagged structure is the ______ of scapula. - ProProfs

    The proximal attachment of the tagged structure is the ______ of scapula.

    • Infraglenoid tubercle

    • Coracoid process

    • Glenoid labrum

    • Supraglenoid tubercle

    • Acromial process

    Correct Answer
    A. Supraglenoid tubercle
    Explanation
    The proximal attachment of the tagged structure refers to the point where the structure is attached to the scapula. In this case, the correct answer is the supraglenoid tubercle, which is a small bony projection located above the glenoid cavity of the scapula. This tubercle serves as the attachment site for the long head of the biceps brachii muscle, which plays a role in shoulder and arm movements.

     Identify the tagged structure: - ProProfs

     Identify the tagged structure:

    • Superior glenohumeral ligament

    • Tendon, long head of biceps brachii muscle

    • Middle glenohumeral ligament

    • Coracoacromial ligament

    • Inferior glenohumeral ligament

    Correct Answer
    A. Middle glenohumeral ligament
